Dear MockK, Repeat After Me

The project I’m working on is using Mockk in the unit tests. It’s a great library that has made true unit testing so much easier. I ran into a problem, though, where I needed a method I was mocking to return the value it was receiving. To be more specific, we were passing an object to a Spring repository method that had been built inside the method to test, and, to test thoroughly, I needed to get to that object. Turns out, that’s pretty easy to do with Mockk. Let’s take a look…

In this post, I’ll show how remarkably simple it is to test Spring Repositories using Flyway to set up schemas and test data.
