In AngularJS, why does introducing view logic (like jQuery) into controllers adversely affect testability?

Question

I am new to Angular and coding from "testing". I understand that introducing view logic into controllers is not an "Angular Path", but it does not understand why this negatively affects testability.

Answer 1

Because it relies on having a DOM for testing. You should be able to test the controller logic without creating a DOM, because you just have to mock the dependencies and then test the data in the constructed view model.
