Property Based Testing Essentials

Property-based testing isn't about testing one set of inputs and asserting an output; it is about testing many random inputs and asserting against a property or rule of what you are trying to achieve. You can use property-based testing against domain code or computation, but we will explore databases in this session.

First, we will discuss the principles of property-based testing (PBT) using JQwik. Then, we will discuss what 'Arbitrary' is and how to use it to create custom objects for our test. We will then wire it together with Test Containers, which bootstraps actual databases of your choice, thus providing a complete solution and enabling us to deliver quality in our repository code. We will also discuss how this can be used in all levels of testing, like E2E and Acceptance Testing
