What is API Testing? API testing is a type of testing that is used to evaluate that the API functions as expected. Software testing professionals analyse and test the APIs and evaluate whether APIs meet the expectations or not and are secure, robust and reliable. Why API testing is important? API is an inherent part of any software application. It’s the “middleman” of the layers and systems within an application or software. API testing is essential as it ensures a reliable, safe, and secure connection between platforms. API testing enables us to find bugs at an early stage hence it is cost-ef ..read more

CRUD (Create, Read, Update and Delete) operations are the fundamentals of API’s.In this article, we will delve into the process of testing CRUD operations in Postman. What is Rest Representational state transfer known as Rest is an architecture style, that was created to guide the development of the APIs. It uses XML or JSON to send or receive data and transfer is over HTTP only. CRUD operations: CRUD stands for Create, Read, Update and Delete. These are four primitive database operations that map well to the HTTP verbs most frequently used in Rest Services. Create : (Post) Used to create a n ..read more

In this article, we will learn What is GraphQL API, How it is different from Rest services and how we can test GraphQL Using Postman. What is GraphQL? GraphQL is a data query and manipulation language for API. It was developed by Facebook in 2012. It is becoming a preferred alternative to Rest Services as it simplifies data fetching for applications and gives the ability to query only the required information through a single end-point. Advantages Of GraphQL Here are a few advantages of GraphQL: Apps using graphQL are fast and stable because GraphQL queries return exactly what we need, Not Mo ..read more
