Informal AMA: Angular Signals RFC
Is the Angular team aware of NG Mocks and NG Spectator?

Services needed in every components unit test
No neither of those. You're unit testing the component, so you don't want any external interference. You can create a mock version of the service, I like using ng-mocks to simplify a lot of this: https://www.npmjs.com/package/ng-mocks

Is Unit Testing in Angular overrated?
No way, you just mock the services. Check out this library: https://www.npmjs.com/package/ng-mocks

Spec file "Cannot read property of 'subscribe' of undefined"
Also, for mocking, I recommend looking into ng-mocks. https://github.com/ike18t/ng-mocks It makes mocking really easy.

Unit testing library for Angular application
Correct. When unit testing, you want to test the unit (parent component) in isolation. To do this, you can use something like ng-mocks (my personal favorite) to create mock components. You could also use the NO_ERRORS_SCHEMA but I don't recommend this because I like to verify that my component loads w/ all of its dependencies (even if the are just mocks). If you test your parent component w/ all of its child components, then you are doing a form of integration testing. I tend to refer to it as a grey area between unit and integration testing because there are valuable tests that can be written fairly easily and cheaply that don't truly isolate parent components from their child components.
