As a developer, unit tests are something you have mastered. Testing some behaviour by identifying a few relevant examples has become almost automatic to you… However, is this approach as natural as it seems? Wouldn’t you agree that your tests could describe the business domain more efficiently, without bothering with examples and the bias they introduce?

This is the main idea behind Property-Based Testing: unlike the traditional “Example-Based” testing, you get to define the “properties” that you want your code to exhibit, and then it’s up to the engine to try and find examples that will expose your mistakes!

The purpose of this workshop is to get a feel for Property-Based Testing with Java / JUnit 5 framework Jqwik. You will end up with a clear picture as to why it would make your job easier, when to use it and when not to, along with everything necessary in order to start using it in your projects!
