What are the best practices for using Jest in testing?
Some best practices for using Jest include writing clear and descriptive test names, using beforeEach for setup, and keeping tests isolated.
Can you explain why isolated tests are important?
Isolated tests ensure that each test runs independently, making it easier to identify failures and maintain the test suite.
What about mocking in Jest? Any tips?
When mocking in Jest, use jest.mock() for modules and ensure to restore mocks after tests to avoid side effects.
How can I improve the performance of my Jest tests?
To improve performance, consider running tests in parallel, using --runInBand for sequential execution, and optimizing test setup.
