How do I mock services in Angular and React?

In Angular, you can use Jasmine's spyOn to mock services. In React, you can use libraries like Jest or Sinon.

Can you give me an example of mocking a service in Angular?

Sure! You can create a mock service like this: const mockService = jasmine.createSpyObj('ServiceName', ['methodName']);.

What about mocking in React? How does it differ?

In React, you can use Jest's jest.mock() to mock modules. It allows you to specify the behavior of the mocked module.

Are there any best practices for mocking?

Yes, keep your mocks simple, avoid over-mocking, and ensure they reflect the actual service behavior as closely as possible.
