About this course
The journey
Tests are what let you change code without fear. This course starts with your first xUnit test and builds up to a full test suite for a small web API, including integration tests against a real database in a container.
You learn how to structure tests, when to mock and when not to, how to test time and randomness, and how to run everything in a CI pipeline on every push.

Rated 5.0 out of 5Testcontainers chapter is gold
Integration tests against a real database in a container replaced our fragile in-memory fakes. Well structured from start to finish.
