What is mocking in JavaScript tests?
Mocking in JavaScript tests refers to creating simulated objects or functions that mimic the behavior of real ones. This allows you to isolate the code being tested and control its environment.
Why should I use mocking in my tests?
Using mocking helps to ensure that your tests are reliable and fast. It allows you to test components in isolation without relying on external systems or dependencies.
Can you give me an example of mocking in a test?
Sure! If you're testing a function that makes an API call, you can mock the API response to return a predefined value, allowing you to test how your function handles that response.
What libraries can I use for mocking in JavaScript?
Popular libraries for mocking in JavaScript include Jest, Sinon, and Mocha. Each has its own features and benefits for creating mocks.
