How do I test dependency injection in Angular?
To test dependency injection in Angular, 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 test file and use TestBed to declare your component and its dependencies. Here's a simple example...
What if I have a service that needs to be mocked?
You can provide a mock service in the TestBed configuration. Just use the 'providers' array to include your mock service.
Are there any best practices for testing with dependency injection?
Yes, always isolate your tests, use spies for service methods, and ensure your tests are easy to read and maintain.
