In this article, i’ll detail the process to unit test the stepper directive we’ve created in the last week custom component creation article. Next week, i’ll cover how to distribute your component via GitHub and Bower.

Unit testing is the art of testing individually every smallest part of your code, which are the foundations of your apps sanity. Once correctly tested, these parts assembled together will also play nicely, as their behaviour has already been validated independently.

Unit testing helps you prevent regressions, increase quality, maintenability, and trust in your codebase, thus better team collaboration, easier refactoring… and WIN :)

Another usage is, when you get a new bug report, you add the revelant test that demo the bug, fix it in your code so the test will pass, then keep it there as a proof of reliability.
