How to test nestjs modules?
Create a mock of the Repository that you're testing, it's the simplest one and the more cumbersome one, you can use a library like jest-create-mock-instance or jest-mock-extended or ts-auto-mock to create a mock from typings, but you're responsible to implement how it supposes to work.

Test interceptor
You can use something like jest-mock-extended or @golevelup/ts-jest to mock it, and whether your interceptor has dependencies or not, can be more complex or simpler how you instance it.

No way, you just mock the services. Check out this library: https://www.npmjs.com/package/ng-mocks

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.
