How can I effectively handle errors in mocking during testing?

Handling errors in mocking is crucial for reliable tests. You can use try-catch blocks to manage exceptions.

What are some common errors I should be aware of when mocking?

Common errors include incorrect mock setups, not resetting mocks between tests, and failing to simulate edge cases.

Can you give an example of a mocking error and how to fix it?

Sure! If a mock returns undefined when it should return a value, ensure the mock is set up correctly with the expected return value.

How do I reset mocks between tests?

You can use the jest.clearAllMocks() function in Jest to reset all mocks before each test.
