How do I test Angular dependency injection?
To test Angular dependency injection, you can use the TestBed utility to configure and create an Angular testing module.
Can you give me an example of how to set it up?
Sure! You can create a testing module using TestBed.configureTestingModule and provide the necessary services.
What about testing a component that uses dependency injection?
For components, you can create a fixture using TestBed.createComponent and then access the injected services through the component instance.
Are there any best practices for testing with dependency injection?
Yes, it's best to isolate tests, use mocks for services, and ensure that your tests are independent of each other.
