A cheat sheet to remind myself the most important kubectl commands. If I do forget then I recommend the VS Code Kubernetes plugin and remember to use --help if you get stuck, start with kubectl --help . I had to use kubernetes again after not using it for about a month and I had forgotten everything I had learned before. So I rummaged through my previous notes and collated the commands I’ve mostly used. To help them stick in my head I categorised them with natural language terms “Where am I?”, “what is this doing?”, etc. Official Cheet Sheet The official kubectl cheat sheet is much bigger than ..read more

Are you recruiting people, or are you recruiting to fulfil a role? Here are tips and notes about recruiting and interviewing. Recruiting vs filling a role Too many companies seem to want to fulfil a role and bring in a candidate who ticks the right boxes in theory; instead of hiring individuals who can do most of what you want now, learn how to do the rest, and can offer you more than you thought you needed and take you to a level you never imagined. When you recruit to fulfil a role you might: assess against a checklist, objectively weight points against specific attributes, and when you empl ..read more

The Triangle Problem is a ‘classic’ from Software Testing, described in many books and training courses. This post describes the problem, links to some applications you can use to practice on and describes some nuances around the testing. What is The Triangle Problem? The application context surrounding the Triangle Problem is usually: Given an application which takes three inputs, each representing the length of one side of a triangle, the application will respond with a message identifying if the inputs are: invalid, or represent a triangle, if they represent a triangle then the application ..read more

TLDR: Every time we test something we are testing from models. Modelling is a key skill for Software Testers. Errors cannot be identified without a model to compare them. Quality Control cannot be conducted without a model. Modelling “A map is not the territory it represents, but, if correct, it has a similar structure to the territory, which accounts for its usefulness…” A. Korzybski, Science & Sanity, 4th Ed. 1958, pp. 58-60 (quoted from: R Bandler & J Grinder, Patterns of the hypnotic Techniques of Milton H. Erickson, M.D. Vol 1, 1975, pp 181) Human beings model the world. We lear ..read more

Content Summary for June 2023 EvilTester.com and Patreon with some recommended podcasts. Overview I managed to create two podcast episodes in June. I was hoping to create an episode every two weeks but it might well only be once a month. The last two episodes took quite a lot of research and thinking about to condense quite a lot of information into a short space of time and try to keep it coherent. The Test Cases and Test Scripts Episode The Test Automation Pyramid Episode I don’t listen to a lot of podcasts because they often take too much time. I find that I can’t listen to a podcast in t ..read more

This episode covers the Test Automation Pyramid, created by Mike Cohen in 2008-2009 in the book “Succeeding With Agile”. We will go beyond the diagram and look at the model that supports it. Then deep dive into the model to explore it’s meaning in relation to Automated Execution Coverage, not Testing. This was released to Patreon supporters early, with full transcript and no ads. Introduction Subtitle: The Test Automation Pyramid: Demystifying a Simple Model I want to talk about the test automation pyramid, or as some call it, the test pyramid. We are going to dive into its origins, the miscon ..read more

Content Summary for March, April, May 2023 EvilTester.com and Patreon. Overview I didn’t manage to get around to uploading the summaries for March, April and May until now so I’ve combined them all together in one post. A few things happened over the last few months which have taken my attention. Twitter changed their API access and pricing, and that completely broke my Twitter Client Chatterscan.com. The API costs make it completely non-viable, which is a pity as it really helped me read Twitter so now I barely use the platform. The only functionality that I could salvage was the ‘favourites ..read more

The most common Testing Entities that I’ve encountered over the years are: Test Condition, Test Scenario, Test Case, Test Script. In my Testing I pretty much now have: Test Idea, Test Log (Execution Log). Is there any value in the original Testing Entities? There might be if we view them as logical concepts, but not really as physical artifacts. This was released to Patreon supporters early, with full transcript and no ads. Test Entities The closest to “Test Script” is that I would map that on to an @Test annotated method for automating the execution and assertion of specific conditions. Lega ..read more

Top 3 Phrases that should carry trigger warnings for the Test Community: Manual Testing, Test Automation, Quality Assurance. In this episode I’m going to talk about Manual Testing. And I’m going to talk about what we might want to say instead of “Manual Testing”. This was released to Patreon supporters early, with full transcript and no ads. One Thing in Common And they all have something else in common. They are all noun phrases. I try to think in “Verb noun” phrases to keep communication simpler and less vague. I don’t want to police the language that other people use, I want to police the l ..read more
