An example of an AI chatbot conversation about best practices for mocking in JavaScript.
What are the best practices for mocking in JavaScript?
Some best practices include using libraries like Jest or Sinon, keeping mocks simple, and ensuring they are isolated.
Why is it important to isolate mocks?
Isolating mocks helps ensure that tests are reliable and only fail due to the code being tested, not external dependencies.
Can you give an example of a good mock?
Sure! For a function that fetches user data, you can mock the fetch call to return a predefined user object.
What should I avoid when mocking?
Avoid over-mocking, as it can lead to tests that don't accurately reflect real-world scenarios.
