Not all web browsers are created equal. Some are exclusively compatible with certain operating systems, while some boast features they claim others lack, like privacy mode and auto-updating. Some browsers even restrict certain features to a specific operating system. For example, Safari’s text-to-speech feature works exclusively with Mac operating systems. There are web browsers that were once praised as the frontier leaders in web exploration and the pioneers of internet navigation that are now nearly extinct- so old and under-used that the younger generation of web users often have never even heard of them. With so many variables on the surface, there are even more differences underneath, that impact the way websites and web applications display and behave across different browsers. Due to this reason, when a web application or software is in the process of being completed, it is a good practice to conduct cross-browser testing.

Cross-browser testing is a technique of testing web applications across multiple browsers. It tests whether the application is working perfectly across all the browsers as expected and degrades gracefully.

But why do different browsers respond differently in the first place?

Each browser has a different rendering engine, which means that they have different rules on how the browser should work, making them read and display content differently. Pair that with different devices and systems, and there is an infinite number of ways to experience the web. This gets more difficult because, most of the time, developers only work on a single machine, which means they are only seeing the end result in one configuration.

Why is it Important?

A web application or software that runs perfectly as desired on one web browser might encounter some issues, or some of its vital functionalities might stop working altogether when running in another web browser. Additionally, there are a number of client components that can generate different results depending on the browsers they are run with, such as AJAX requests, Flash, JavaScript, Applets, and so on.

Cross-browser testing has become more important than ever before. The process that was once used only by the most complex projects has now become mainstream. As more and more people create websites, the only way to stand out from the crowd is to have a really professional website. But, what if the end-user is using Internet Explorer? You don’t want to leave them out. Even more, with the rise of responsive web design, having a responsive website that works is all browsers has become incredibly hard.

There are many browsers currently operating in the market, each with multiple versions. With every new version of the browser, it becomes difficult to check if your site is supported by that version. Cross-browser testing tools make it easy to test your site on multiple browsers and their multiple versions. Some of the widely used browsers include-

  • Chrome
  • IE
  • Firefox
  • Safari
  • Android Default Browser
  • UC Browser
  • Opera

The percentage of usage and market share may differ based on the region. An organization should make sure that most of these browsers are supported.

Features Analyzed in a Cross-browser Test

You can categorize the features that will undergo testing like this:

  • Base Functionality – It ensures that the basic functionality works on most of the browser-OS combinations
  • Design – This ensures that the websites appearance- fonts, images, and layout matches the specifications shared by the design team
  • Accessibility – accounts for compliance with Web Content Accessibility Guidelines to enable differently-abled users to access the website
  • Responsiveness – Verifies that design is fluid and fits different screen sizes/orientations

With the help of Cross-browser testing a company can provide the best experience possible to all the customers. While it’s often one of the biggest pain points for development and QA teams, it is worth spending the time to make sure you’re covering all major browsers you support.  Even if the majority of your users are accessing your site on one browser, make sure all major features and components are functional on less popular browsers.  If you say you support a browser, make sure you actually do proper testing on that browser to avoid any surprises.

One of the major responsibility of a front-end developer is to make sites that are built, visibly acceptable across the browsers the project has decided to support. Most of the times, more than one! The sites can be visibly acceptable after cross-browser testing. Browser testing is an essential step in the website creation process. As a web developer, you have limited control over how your final product will display across the various browsers. Several web elements may not show as expected, and as a result, can have an unfavourable effect on the website and its messaging.

Cross-browser testing is the process of assessing different websites and applications across the possible browsers in order to make sure the web content reveals and works correctly for all the customers.

Today, we will be discussing the different tools used for completing the task of cross-browser testing.

1. Browserstack

This is one of the most popular tools in the market. Browserstack is a cloud-based tool that doesn’t require any software to be downloaded or installed. It allows for testing of over 2000 browsers and real devices of various sizes and resolutions. Further, the features include local testing, quick screenshots, and many more. A nifty feature for developers, BrowserStack also includes pre-installed developer tools. Not only do these help with cross-browser testing but they also assist with code debugging as well.

2. Endtest

Endtest is a platform that allows you to create, manage, and run automated tests for web applications and native mobile applications, without having to write any code. It has some exciting characteristics like-

  • Cross-browser grid, running on Windows and macOS machines
  • Codeless Editor for Automated Tests
  • Support for Web Applications
  • Support for both native and hybrid android and iOS apps
  • Unlimited Video Recordings for your test runs
  • Screenshot Comparison

It is truly a powerful platform.

3. LambdaTest

It is a powerful tool that allows you to test your website across a pretty huge list of browsers and their respective versions. The reason why LambaTest is on this list because the tool is genuinely faster than most of the tools, especially with desktops, and they seem to focus more on customer satisfaction as their response to user problems is really quick. The tool has a really clean UI and provides an easy to use testing experience.

4. Ranorex Studios

This tool is an all-in-one solution for cross-browser testing. It has automated tests for a broad range of web technologies and frameworks including HTML5, Java and JavaScript websites, Salesforce, Flash and Flex applications, and many more. Ranorex even supports cross-domain iframes, elements in a shadow DOM, hybrid desktop applications based on the open-source Chromium Embedded Framework (CEF) and the Jx Browser.

5. Selenium

Selenium is one of the most popular structures out there and allows you to automate browser actions. You have a pair of options: Selenium IDE is a Firefox add-on which will let you record and playback actions, or Selenium WebDriver, which allows you to code tests in almost any major language of your choosing.

6. Browsershots

Browsershots is an open-source web browser testing platform. It allows one to test a website in any browser and operating system. In this tool, you can run cross-compatibility tests with great customization options like operating system, browser type, colour depth, JavaScript status, and flash enable/disable settings. Browser shot allows you to take website screenshots in almost 61 browsers and various operating systems.

7. Functionize

What separates Functionize’s cross-browser testing tool from its competitors is its widespread use of artificial intelligence and the fact that if you set up tests for one browser, then there’s no need to recode tests for others, which can save a decent bit of time. It’s not defined how many browsers Functionize supports, however, they offer the same standard of characteristics as with other cross-browser-testing tools, such as code debugging and visual testing.

Although, the majority of cross-browser testing tools in the market today have maintained a high standard in terms of features offered, allowing development teams to increase their test coverage and deliver a more consistent user experience across all the devices, many of them have a least small trait that sets them apart from their competition. At last, your’s is the ultimate choice.

The last few years have seen an overwhelming evolution of the software testing industry giving way to greener pastures. As we already know, ensuring effective software application performance is one of the highlights of software testing. But, how does testing ensure that the software is running error-free? In this article, we will provide you with detailed knowledge about different stages involved in Software Testing Life Cycle (STLC).

Software Testing Life Cycle

Software Testing Life Cycle is defined as, a series of activities conducted to perform software testing. It identifies what test activities to carry out and when to accomplish those test activities. In the process of STLC, each activity is carried out in a planned and systematic way, and each phase has different goals and deliverables. Let us quickly see what are the different stages involved in a typical STLC.

Stages of Software Testing Life Cycle

There are six main stages in this life cycle. Each stage has its own entry and deliverable criteria. The stages are as follows;

  1. Requirement Analysis
  2. Test Planning
  3. Test Case Development
  4. Environment Setup
  5. Test Execution
  6. Test Cycle Closure

Let’s now discuss what all activities and deliverable are involved in each step in detail.

1. Requirement Analysis

This is the first stage in a Software Testing Life Cycle. Under this phase, one has to analyze and study the requirements. The organization, typically identifies the content, release theme and timeline. Requirement analysis involves a detailed analysis of risk involved and whether the requirements are testable or not. If any requirement is not testable, the test team can communicate with various stakeholders during this phase so that the mitigation strategy can be planned.

2. Test Planning

Under this stage, the test manager/test lead involved, determine the effort and cost estimates for the entire project. The actual engineering as well as writing the application keeping into consideration the requirements established in the first stage. Here, the testers identify the metrics and the method of gathering and tracking those metrics. The feasibility of the software project is tested after using different algorithms. 

3. Test Case Development

Under the third stage, a code is built and integrated. This is the prime focus of the developers and it is one of the longest phases of the entire Software Testing Life Cycle. The test team prepares test cases, test scripts, and test data. Once everything is ready, the test cases will be reviewed by the peer member and the team lead. Here, the Requirement Traceability Matrix (RTM) is also prepared. The Requirement Traceability Matrix is an industry-accepted format for tracking requirements where each test case is mapped with the requirement. Using this RTM we can track backward & forward traceability.

4. Environment Setup

This phase can be parallelly started with the test design phase. The environment setup of the test is done on the basis of the hardware and software requirement list. In some cases, the test team may not be involved in this phase. Development team or customer provides the test environment. Meanwhile, the testing team should prepare the smoke test cases to check the readiness of the test environment setup.

5. Test Execution

In this phase, the testing team will start executing test cases based on the prepared test planning and priorly prepared test cases. Once this test case is passed then the same can be marked as Passed. If any test case is failed then the corresponding defect can be reported to the developer team via the bug tracking system & bug can be linked for a corresponding test case for further analysis. Also, if any of the test cases are blocked due to any defect then such test cases can be marked as Blocked, so we can get the report based on how many test cases passed, failed, blocked or not run etc

6. Test Cycle Closure

This is the final stage where the test closure report, test metrics are prepared. The testing team will be called out for a meeting to evaluate cycle completion criteria based on the test coverage, quality, time, cost, software, business objectives etc. Test team analyses the test artefacts (such as Test cases, Defect reports etc) to identify strategies that have to be implemented in future, which will help to remove process bottlenecks in the upcoming projects.

STLC planned and executed the right way can allow the highest level of management control and documentation. Developers understand what they should build and why. All parties agree on the goal up front and see a clear plan for arriving at that goal.

Let us now summarize the Software Testing Life Cycle with a table.

STLC Stage Entry Criteria Deliverables
Requirement Analysis Business Requirement Specification List of all testable requirements, Automation feasibility report (if applicable)
Test Planning Updated requirement documents and test feasibility reports Test Plan document and Risk mitigation document
Test Case Development Updated requirements document, Test conditions document Detailed test condition document

Requirement traceability metrics

Environment Setup Test Plan, Smoke Test cases, Test Data Test Environment. Smoke Test Results.
Test Execution Test Plan document, Test cases, Test data, Test Environment. Test case execution report, Defect report, RTM
Test Cycle Closure Test Case Execution report (make sure there are no high severity defects opened), Defect report Test Closure report, Test metrics

In the present time, the increasingly complex environment of software testing requires comprehensive and elegant solutions. This means that developers need to juggle with several tools as well as technologies while generating code that would perform the efficient level of digital business. We at 99tests have successfully mastered the art of efficiency. 300+ companies worldwide including P&G, Intuit and security scorecard are our clients. We would be happy to increase our family.

Software Testing Standards are a set of rules or standards that are expected to be met in a particular product or service offered by a company. Compliance to these set of rules is mandatory for a company as it defines the extent to which a company is performing its duty legally and is not engaged in any sort of malpractice. Moreover, doing so will also ensure the delivery of high-quality products.

There are many organizations around the globe who develop and implement different standards to improve the quality needs of their software. This article briefly covers some of the widely used standards related to Software Testing.

Latest Software Testing Standards

Standards for software testing are developed by the International Standards Organization (ISO), the International Electrotechnical Commission(IEC), and the Institute of Electrical and Electronics Engineers (IEEE). 


As of 2018, ISO/IEC/IEEE 29119 which consists of five international standards is prescribed for software testing. It was developed in the year 2007 and released in the year 2013. Let us get information on the same one-by-one.

1. ISO/IEC/IEEE 29119 (Part 1- 2013)

This software testing standard focuses on meaning, definition and different concepts of all the other standards in the 29119 series. It helps an individual in understanding the vocabulary on which other standards in the series are built as well as provides relevant examples to show the way in which each concept works in practice. In short, this standard provides an overview of software testing concepts and helps in understanding the concepts presented in this series.

2. ISO/IEC/IEEE 29119 (Part 2- 2013)

This part of the series defines a generic process model for software testing that can be used within any software development life cycle and in any organization. According to this standard, the testing process will work on three layers process that would include organizational test specifications such as organizational test policy and test strategy, test management, and dynamic testing.

3. ISO/IEC/IEEE 29119 (Part 3- 2013)

This standard provides templates for test documentation that covers the entire software testing life cycle. The templates can be tailored to suit the unique needs of each organization and the life cycle model. All the templates align with the test process defined in ISO/IEC/IEEE 29119-2 and can be produced by applying all the processes that are defined in the standard. Since it is designed in alignment with the process defined in the ISO/IEC/IEEE 29119-2, this software testing standard is likely to surpass the IEEE 829 standard.

4. ISO/IEC/IEEE 29119 (Part 4- 2013)

The techniques present in this standard can be effective in a way to develop test cases that can be used to present evidence that each requirement mentioned under the test have been successfully met or there are certain defects that need to be rectified. In short, this series provides standard definitions of software test design techniques (also known as test case design techniques or test methods) and corresponding coverage measures that can be used during the test design and implementation processes defined in Part 2.

5. ISO/IEC/IEEE 29119 (Part 5- 2013)

This standard covers keyword-driven testing, an approach to specifying software tests used in the software testing industry. The keywords are basically the names which are associated with a set of actions that are required to perform a specific step in a test case. By using keywords to describe test steps instead of natural language, test cases can be easier to understand, to maintain and to automate.

ISO/IEC 9126

The standard deals with certain aspects to check and determine the quality of software application. The aspects are as follows:

  • Quality model
  • External metrics
  • Internal metrics
  • Quality in use metrics

It also presents with some basic set of quality attributes for any software such as:

  • Functionality
  • Reliability
  • Usability
  • Efficiency
  • Maintainability
  • Portability
Other Software Testing Standards

There are some other useful standards a software tester must know which are related to QA and software testing. They are:

  1. IEEE 829

This software testing standard is practised in different stages of the testing and is used for proper document formatting.

  1. IEEE 1059

This standard supports in guiding software verification and validation

  1. IEEE 1061

It has the technique to establish better quality and validating the software with the quality metrics

  1. IEEE 12207

It is a standard for software life cycle processes and life cycle data.

  1. IEEE 730

This software testing standard is for software quality assurance plans

  1. IEEE 1044

A standard for the classification of software anomalies.

Implementing the afore-mentioned standards may enable a company to deliver better products in the market as a lot of these are encouraging to follow authentic and reliable software techniques and approaches as a whole.

Whenever any web application or software is released, it is expected to be executed in all the browsers, but it’s not possible as all the web browsers are not created equally. Some browsers are designed to work with specific operating system while the others claim to have boasting features. Keeping this in mind, it is a good habit to conduct cross-browser testing once the process of web application or software is being completed. Cross-browser testing is a technique of testing web applications across various browsers to ensure that all the sites or web apps run successfully on separate browsers. This is based on a range of metrics. They are-

  • Base Functionality- If the links, dialogs, menus are available as required
  • User interface- Does the appearance match the specifications
  • Graceful Degradation- Does the experience adjust between desktop and mobile browser
  • Responsiveness- Does the site change in mobile browsers based on criteria such as resolution, rotation, and location
  • Performance- Does the site load within a suitable frame, while allowing for network connection speed

With cross-browser testing, the testers can write test, configure the supporting browser, and test to verify whether the software runs perfectly in different browsers.

Testing Types in Cross-Browser Testing

There are basically two types of testing. They are as follows-

  1. Automated Testing- It is the ability to set up tests which can be run with little, or no, deliberate human intervention
  2. Manual Testing- It requires conscious the involvement of human tester to verify the functionality of an application or website

Let us now know how both the methods are used for cross-browser testing.

Automated Method

Since cross-browser testing is all about running the same set of test cases multiple times on different browsers, it is typically a repeated task and best suited for automation. It’s more cost and time efficient to perform this testing using some tool. There are a lot of tools available in the market to make things easier

Manual Method

In this case, a business identifies the browsers that the apps must support. Testers then re-run the same test cases using various browsers and observe the behaviour of the applications and report bugs if any. It can get difficult to cover all the browsers in this type of testing and also, the application might not be tested on significant browser versions. It is also costly and time-consuming.

Process of Cross-Browser Testing

The workflow or the process of cross-browser testing can be broken down into five steps. They are as follows-

  1. To determine what browsers to test you need to check the traffic statistics. It means, in the browser where there’s less user engagement or fewer users overall, that browser needs to be tested.
  2. Detailed analysis must be performed on the AUT (Application Under Test) to determine what parts of the application or if all of it has to undergo this. It is advisable that all of it shall be tested on multiple browsers after taking into consideration the cost and time involved in testing each browser. A good strategy can be performing a complete test on one browser per platform and for the other just test the most critically used functionality
  3. After the what’s and where’s of a browser testing is solved, decisions on infrastructure must be made, like, do we acquire tools or test is manual etc. here too, the cost must be taken into consideration. Few more things to be addressed under this stage are- viability, risks, security concerns, people that are involved, time acceptance criteria, issue/defect fixing schedule etc
  4. Now is the time to perform the testing. The regular functional testing test cases can be used when validating the efficiency of this system. For look-and-feel/rendition test cases are not necessary.
  5. Once you get the results, report it back to the design team, if they are not involved in the testing process. The changes can be made after this step.

This is the usual process followed for cross-browser testing. The important question that arises here is, when is the right time to test? Any testing reaps the best benefits when it is done early on. Therefore, it is recommended to start as soon as the page designs are available. It can also be performed when the website is fully integrated and functional. But, if the cross-browser is not completed during the aforementioned stages, it can still be done while the application is in production. However, this is costliest of all and risky too.

Last few years have seen a massive increase in the web. There is so much content to look for in the web that one lifetime would not be enough to go through it all. You can find A to Z of life on the web. And people are viewing this content on more than 3,000 web browsers. Now, more users mean more devices, more platform, more browsers and ultimately more ways in which your website can be viewed. Here the company’s major concern should be questioning whether the users see the website the same way you want to see them in each browser?

The growth in the web has also resulted in multiple types of technologies to build this web ecosystem, and a significant diverse tool, like a web browser to access and interact with this content. But, not all technologies are mutually compatible with each other. A web developer has to always make sure that their website is compatible with every technology and here arises the need for cross-browser testing.

Cross-browser testing is the process of testing a website or a web-app across numerous browsers, browser versions running on different systems to ensure rendering of the website stays as intended. In short, the main reason behind performing cross-browser testing is to evaluate the efficiency of the software product to perform and across multiple browsers accurately. Apart from the compatibility of the browser, it also ensures the similar and accurate working of the software product on all browsers.

Features of Cross-browser Testing

When the competition among different companies is at the peak, it is vital for them to test their software systems with different web and mobile browsers. This can be accomplished with the help of cross-browser testing, whose characteristics are described below:

  • Its primary feature is to perform testing of web application across different browsers
  • It can be carried out manually or with the help of specific tools like BrowserStack, SauceLabs, etc
  • By testing the web app, it ensures compatibility with each known and popular browsers
  • It involves having a Quality Assurance (QA) team with other teams such as business team, marketing team, designing team, client etc. they help in determining the scope of the testing like, which browser to choose, at what extent, the testing is required to be carried out, and such other things
Why do you Need Cross-Browser Testing?

A normal website is comprised of three major technologies i.e. HTML, CSS3, and JavaScript. Even though there are other 100s of technologies that are present in the backend like Python, Ruby, etc. but in the frontend and in the rendering, only the three mentioned technologies are being used. Each browser uses a different rendering engine to compute these three technologies. Like, take for an example, Chrome uses Blink, Firefox uses Gecko and IE uses HTML and Chakra, due to which the website will rendered completely but all these different browsers. And that is why you need cross-browser testing.

The website needs to function properly on all types of browser and in all the operating systems. So to ensure that it works fine, we require the help of cross-browser testing.

Other such reasons for needing cross-browser testing are as follows-

  • Most of the times, the end users are not necessarily choosy with a particular browser. They have willful access to various types of browsers and mays switch whenever they feel the need to do so, depending on the accessibility and their personal choice
  • It is also possible that the software may not work on every browser. But this time, the inability is from the browser side to allow the software product consolidated with the best and the advanced technologies. Under such cases, the cross-browser testing helps in determining the effects along with the potential changes that may be executed in the software product in order to make it congenial with each browser
  • Every browser has its own design, architecture, and specifications etc. which make your web page’s style and appearance different from others. Therefore, it might be possible, that the data or coding, which is confidential, and the developer does not want to disclose it, for the security purpose, such as hacking, cracking, etc., may get explore or gets visible, in one or more than one browser.
Advantages of Cross-Browser Testing

Just like any other software testing technique, cross-browser testing also offers various benefits, some of which are mentioned below:


  • User Approachability
  • Offers a positive company image
  • Accurately detects errors and issues in the system
  • Improves browser adaptability

Apart from these advantages, cross-browser testing allows the team of testers to validate the behaviour and functionality of the website, application, and software while ensuring its compatibility with multifarious browsers.

If all browser vendors followed open web standards uniformly, then cross-browser testing wouldn’t have been needed. But we live in a world where browsers compete for market share. The onus is on you to deliver an end-user experience that’s consistently delightful across a multitude of browsers and devices.

Before any software product releases, it goes through various levels of testing to make sure that it is working properly. These levels identify missing areas and prevent overlap and repetition between the development of life cycle phases. In a software development lifecycle models, there are defined phases like requirement gathering and analysis, design, coding or implementation, testing, and deployment. Each phase defines a different level of testing. The four levels of software testing are as follows.

  1. Unit Testing
  2. Integration Testing
  3. System Testing
  4. Acceptance Testing

Let us now understand what happens in each level one-by-one.

1. Unit Testing

Under this type of testing, individual sections or parts of software or product are to be tested. This testing is performed at developers end to make sure that their code is working well and meets the specifications as mentioned by the user. The ultimate aim of a Unit Testing is to divide every part of the program and test that the separate part is working perfectly. In addition to testing units separately, this testing also performs several other functions like;

  • It ensures that all the statements in the unit have been executed at least once
  • It ensures that data structures that represent relationships among individual data elements
  • It checks all arithmetic calculations present in the unit with all possible combinations of input values.
2. Integration Testing

This testing allows individuals the opportunity to combine all of the units within the program and test them as a group. This testing is designed to find interface defects between the modules/functions. It basically checks the data flow from one module to other modules. The ultimate purpose of Integration Testing is to expose faults and interaction between integrated units. Some other points with regards to integration testing are listed below;

  • It ensures that all modules work together properly and transfer accurate data across their interface
  • It is performed with an intention to uncover errors that lie in the interface among the integrated components
3. System Testing

In this type of testing, the system is tested against non-functional requirements such as accuracy, reliability, and speed. The main purpose of this testing is to validate and verify the functional design specifications and to check how integrated modules work together. System Testing is performed in an environment that closely mirrors production. The testing is considered to be complete when the output is produced by the software and the outputs expected by the users are either in line or the difference between the two is within permissible range as specified by the user.

4. Acceptance Testing

Acceptance Testing is conducted to find if the requirements of a specification or contract are met as per its delivery. Under this testing, the team will utilize a variety of methods, such as pre-written scenarios and test cases to test the software and use there results obtained from these tools to find ways in which the system can be improved. The advantages of acceptance testing are;

  • It gives the user an opportunity to ensure that the software meets the user requirements before accepting it from the developer
  • It determines the readiness of the software to perform the operations
  • It decreases the possibility of software failure to a large extent

These testing levels cannot be applied haphazardly during the development. There is a logical sequence that should be adhered to in order to minimize the risk of bugs cropping up just before the launch date.

The software testing cycle is a time-consuming process that involves various methodologies and techniques. Testers and developers use their experience and knowledge to create products that are of exceptional quality and are designed as per the requirement of the clients. However, the most integral part of the software development process is testing, which is executed in the software through several levels. At 99tests, we believe in presenting the perfect product for you. Our qualified team of testers has years of experience in software testing services and can make sure that the product is free from bugs.

A use case is a method of identifying, articulating, and arranging systems requirements in software development. Based on the use case, software functionality is developed by engineers. A use case is a tool for defining the required user interaction. If you are trying to create a new application or make changes to an existing application, several discussions are to be made. One of the critical discussions you have to make is how you will represent the requirement for the software solution. Business masters and developers must have a mutual understanding of the requirement, as it’s very difficult to accomplish. Any standard method for structuring the communication between them will really be a boon. It will, in turn, reduce the miscommunications and here is the place where Use case comes into the picture.

What is a Use Case?

A use case is a description of a particular use of the system by a user. It is used widely in developing tests at the system or acceptance level. A use case is made up of a set of possible sequences of interactions between systems and users in a particular environment and related to a particular goal. It consists of a group of elements that can be used together in a way that will have an effect larger than the sum of separate elements combined. A well-written case must have the following characteristics;

  • Model the user goals when using the software
  • Record the scenarios that bring the user to the goal
  • Denote the main course of actions, as well as alternatives
  • Organize functional requirements
  • Be multi-level  and utilize the functionalities of other use cases

Use cases describe the process flows through a system based on its most likely use. This makes the test cases derived from use cases particularly good for finding defects in the real-world use of the system (i.e. the defects that the users are most likely to come across when first using the system)

What is Use Case Testing?

The Use Case testing technique helps in identifying test cases that cover the entire system, on a transaction by transaction basis from start to finish. Use Case testing ensures the important user journeys or important user path are working fine on the system. It is a type of complimentary testing and it does not provide the entire coverage of the applications. Let us now move on to understand the characteristics of use case testing.

Here are the attributes of use case documents in a software testing

  • Organizing functional necessities
  • Use case models the objectives of system/performer connections
  • Use case scenario paths from trigger occasions to objectives
  • Use case software testing procedures portray one principle stream of occasions
  • It is effective in defining the scope of acceptance testing
  • The use case will find out the defects in integration testing

Hence, with the help of use case testing we do and test the end to end flow of all the transactions (positive test case) and also cover the alternate flows (negative test case) based on the user action and system action.

Applicable Testing Levels for Use Case Testing

There are three main testing levels, namely,

  1. System Testing
  2. Acceptance Testing
  3. Performance Testing
Benefits of Use Case Testing

Use case testing provides some functionality which is used to help develop software projects. They are as follows;

  • Use cases start from a very simple view that a system is built first and foremost for its users.
  • Use cases are a sequence of steps that describe the interactions between the actor and the system.
  • Use case help to capture the functional requirements of a system

The main advantage of use case testing is that it helps testers addressing the customers need. Because of the basis for this testing is the use cases, which is nothing but the real transaction users performing. This can sometimes turn into a major weakness of this technique too. In such cases, the use case may not reflect the actual usage scenarios.

In today’s competitive world, internet consumers want to get products to be implemented and updated faster. Customers want more software releases with new features to be implemented in a short time frame, but they don’t like to work with defected software. In a short frame or continuous release, more bugs get piled up into the products. Releasing such software with so many bugs into it may affect the user experience which makes a bad impact on the quality impression of your company brand. They will remember about the delivered bad quality product, and that is where the importance of software testing plays a vital role.

Why is Testing a Software Important?

Any product’s success is gauged by it’s quality and customer reliability on that product. To deliver a product or a software application with high quality, proper testing is required. This enhances the level of support or facilities given to the customers. Moreover, a well-tested product incurs less maintenance cost and so the results delivered are more accurate, consistent, and reliable.

There are several reasons which clearly tells us why Software Testing is important and what are the major things that we should consider while testing any product or application. Software testing is very important because of the following reasons:

1. To Avoid Additional Expenses

People always trust products that are affordable, have low maintenance costs and provide accurate and consistent results. A software or application that is full of glitches can generate additional costs and you can lose your customers.

2. To Gain Customers Confidence

Whenever a customer purchases a product, the decision is made based on the quality of that particular product. A poor quality product can cause customers to lose confidence in you, which can directly affect your business. There to avoid any future errors, it is important to get your software tested.

3. For Security

Another important point to be added is of security. This is probably the most sensitive and most vulnerable part. There have been many situations where customers information has been stolen or hacked and used it for their benefit. That is why people tend to lean towards a reliable product. Testing can help you product security as;

  • The user gets a trustworthy product
  • Keeps user’s personal information and data safe
  • Vulnerability-free products
  • Problems and risks are eliminated beforehand
  • Saves a lot of troubles later on
4. To Increase Product Quality

Products always serve users in some ways, so it’s very important that it brings the value it promises, hence it should work properly to ensure the great customer experience. Development of an application has many processes included and testing  gets glimpse of every bit- it checks if the graphics of the app are aligned properly, tests the main functionality, checks if menus are intuitive etc. after developers fix issues, sometimes another issue may appear unexpectedly, that’s just how testing goes sometimes, so it’s great to find those issues to be resolved and be a part of quality product being delivered to the marketplace.

5. To Determine Software Performance

An application or software with low performance can cloud your image in the market. While you put your software on the market without a test and the performance is not the customer’s expectation, it will be difficult to convince people that it is good.

Among the most important aspects of testing, in today’s competitive market only the quality product stays longtime firmly, so to make sure the produce the good quality product the testing of application is the key factor. After all, for the growth of any business, user satisfaction and testing play an important role to make this happen. But to make this happen you have to plan it properly before executing it. At 99tests, we believe in presenting the perfect product for you. Our qualified team of testers has years of experience in software testing services and can make sure that the product is free from bugs.

Testing is a process consisting of all lifecycle activities, both static and dynamic, concerned with planning, preparation and evaluation of software products and related work products to determine that they satisfy specified requirements. Today’s world of technology is completely dominated by machines and their behaviour is controlled by the software powering it. But what exactly is Software Testing? It’s something that is pretty difficult to compress into a couple of short sentences. In this article, we’ll seek to look at some of the things that software testing is, and isn’t.

Software Testing- All You Need To Know

Software Testing can be stated as the process of verifying and validating that software or an application is completely bug-free, meets the technical requirements as guided by the design and development team and also meets the user requirements effectively and efficiently with handling all the exceptional and boundary cases. The process of software testing aims at not only finding faults in the existing software but also at finding measures to improve the software in terms of efficiency, accuracy, and usability. It mainly aims at measuring specification, functionality, and performance of a software application. Software testing involves examining and checking software through various testing processes. The basic objectives of these processes involve;

  • Verifying the completeness of software in regards to functional or business requirements
  • Identifying technical bugs and ensuring the software is glitch-free
  • Assessing usability, performance, security, localization, compatibility, and installation

The tested software must pass each of these tests in order to be considered complete or fit for use.

Software testing can also be divided into two main steps:

  1. Verification (Are we building the product right?)- It refers to the set of tasks that ensure software correctly implements a specific function
  2. Validation (Are we building the right product?)- It refers to a different set of tasks that ensure the software that has been built is traceable to customer requirements
Principles of Software Testing

Testing software is exceptionally imaginative and an intellectual task for the testers to perform. It consists of some principles that play a significant role in a software tester while testing the project. The software testing principles are as under;

  • It can help in detecting bugs- Testing software can help in revealing a few or some defects that may or may not be detected by the developers. Hence, it’s essential to devise test cases and find out as many defects as possible.
  • Drives for early testing- The earlier you will begin to test your project or software the better you will find to utilize your existing time.
  • Defect in clustering- At the time of testing, one can observe that the majority of defects or bugs have been reported are because of a small number of modules inside a software system.
  • It is context-dependent- Various methods, procedures, and kinds of testing are there which defines the type and characteristics of the application.
  • It follows the Pareto (80/20) rule- The rule states that 80% of errors come from 20% of program components.
Software Testing Approaches

There are three main testing approaches in software testing. They are;

1. White Box Testing

It is based on an application internal code structure. In white-box testing, an internal perspective of the system, as well as the programming skills are used to design the test case.

2. Black Box Testing

Black Box Testing is a software testing method in which testers evaluate the functionality of the software under test without looking at the internal code structure.

3. Grey Box Testing

The tester who works on this type of testing needs to have access to design documents. This helps to create better test cases in this process.

Thus, we can say that software testing is essential because software bugs could be expensive or even dangerous. They can potentially cause monetary and human loss, and history is full of such examples. At 99tests, we believe in presenting the perfect product for you. Our qualified team of testers has years of experience in software testing services and can make sure that the product is free from bugs.
