Tests are part of source control ✅

The test code you write needs to reside in a source control repository, just like your real production code.📦

In fact, you should treat your test code as thoughtfully as you treat your production code. ↔️

It should be part of the branch for each version of the product, and it should be part of the code that developers receive automatically when they get the latest version. 🔚

Because unit tests are so connected to the code and API, they should always stay attached to the version of the code they’re testing.
