Why should we do unit testing with Swift? Unit testing is a crucial part of every SW project. It’s main purpose is to prevent errors from shipping. Unit tests also works as a safety net for you program. If you have written a big piece of code few months ago, and now you need to refactor that, unit tests are your best friend. Unit tests make sure you won’t break anything. If you have written test for all use cases and corner cases, you can be sure even after the refactoring that the application works as intended in the first place.
