In Angular, how can you ensure that your service correctly handles HTTP errors during testing?

Mock the HttpClient responses
Use a delay operator like debounceTime for error cases
Use real HTTP requests with a testing server
Wrap the service call in a try-catch block

To ensure that your Angular service correctly handles HTTP errors during testing, you should mock the HttpClient responses. This allows you to control the responses and simulate error scenarios in a controlled environment. Using real HTTP requests or delay operators like debounceTime is not recommended for testing HTTP error handling.
