AI is now embedded in nearly every aspect of software development. At large companies, AI generates a substantial portion of code, and...

Untrained AI can generate test cases from specifications, but this approach suffers from several critical flaws: ✅ They generate tests...

AI will replace lots of jobs. We show that AI is not a good test designer and makes wrong test cases and omits necessary test cases as...

In this article, we show how you can improve test automation by using AI. In an example, I will show how to add coded custom commands to...

Test automation transcends mere execution; it’s a fusion of test design automation and test execution automation. The key to unlocking...

In the realm of automated testing, outdated test cases can become a cumbersome obstacle. This article explores a proactive approach...

Test flakiness poses a significant challenge in automated testing. In this study, we delve into a more precise definition of flaky tests...

Developers often make mistakes by adding identical IDs or special data-* attributes to different UI objects. Instead of waiting for them...

A common misconception is that a failed test or code should be debugged. On the contrary, if the test implementation is fast enough a...

Your test cases should be independent. However, instead of setting postconditions that will not be executed when a test fails, add an...

It’s always a dilemma about what to do with the failed test cases during execution. Unfortunately, some test cases always fail. There are...

We compare the three classes of model-based testing techniques: stateless, stateful, and action-state.  We show that stateless solutions...

The ratio of the test cases of different test levels is an output, as a consequence of your system and the selected test design...

Twenty years ago, the test-first method became popular thanks to Kent Beck’s famous book Test Driven Development: By Example. You can...

In some sense, testing can be more difficult than coding, as validating the efficiency of the test cases (i.e., the ‘goodness’ of your...

Most test automation tools just do test execution automation. Without test design involved in the whole test automation process, the test...

In my last blog, I investigated both the stateless and the stateful class of model-based testing. Both have some advantages and...

Model-based testing employs models to define software/system behavior and testing strategies, aiding in designing and executing testing...

Why good test design is inevitable? Many books, blog posts, etc. state that either you spend lots of money and time for testing to reach...

Test automation is a hot topic, test design isn’t. However, without appropriate test design, test automation is worthless as you will...
