Welcome back to yet another episode of test purification. In the last part we explored another benefit of adding type parameters to our code, the ability to work with very lean mocks. It's been a…
In the last part we saw how to make our code more declarative, and the tests more functional by introducing type parameters for the inner data flowing through our code. In this part we are going to…
In the last part we learned how to purify our tests using type parameters. In this and following parts we'll see some further benefits of adding type parameters this way.
Here's a fun little trick to purify your tests. When I say "purify" I mean it in the pure functional programming sense of making the tests side-effect-free. But more specifically, I'm going to show…
