In this episode we welcome Younes Jaaida to the Angular Plus Show to talk about Angular testing. To kick things off, Younes shares with us how to redefine the way we define, think, and communicate the testing boundaries. Younes encourages us to think about narrow tests in comparison to non-narrow (or wide) tests.

Younes also shares with how to get started on your testing journey, and provides some tips on writing tests with Angular.
