How can I handle errors in Angular testing?

In Angular testing, you can handle errors by using the try-catch block or by utilizing Jasmine's done callback for asynchronous tests.

Can you give me an example of using try-catch in a test?

Sure! You can wrap your test logic in a try-catch block like this:

it('should handle error', () => {
  try {
    // your test logic here
  } catch (error) {
    expect(error).toBeDefined();
  }
});

What about handling asynchronous errors?

For asynchronous tests, you can use the done callback. Here's an example:

it('should handle async error', (done) => {
  service.getData().subscribe({
    next: () => done(),
    error: (err) => {
      expect(err).toBeDefined();
      done();
    }
  });
});

Are there any best practices for error handling in Angular tests?

Yes, always ensure to clean up after tests, use meaningful error messages, and consider edge cases to improve reliability.
