Angular Unit Tests with the inject() function

Показать описание
In this video, I discuss approaches for unit tests in Angular. I focus on those kinds of tests where the class under test is instantiated manually and gets its dependencies not via the constructor but via the inject function, which was introduced in Angular 14.

Hi Rainer, thx for picking up the topic!
It seems the inject() is rarely used at the moment and also the docs are lacking information.
I recently had issues testing pipes which injects services via inject() method. I managed to successfully test them by using a WrapperComponent which injects the pipe, so I could avoid hacking around, but I would like to see easier ways in the future.
All the best and keep up the good work!

HI Rainer,
Thx for that smart solution.
Does it still work with Angular 17 ? I noticed your sample application is using anguler 15.

Why would one use the inject-function when the 'old' way is clearer in specifying the dependencies and much simpler to test?

The documentation for this is truly embarrassing, they state not to use the old class based guard and to use the new inject function, but how to unit test? God knows...
