What are the best practices for using Jest and Mocha in testing?
When using Jest and Mocha, it's important to follow best practices like keeping tests isolated, using descriptive test names, and leveraging before/after hooks for setup and teardown.
Can you explain why keeping tests isolated is important?
Isolated tests ensure that each test runs independently, which helps in identifying failures quickly and reduces flakiness.
What are some common pitfalls to avoid when writing tests?
Common pitfalls include not cleaning up after tests, writing overly complex tests, and not testing edge cases.
How can I improve the performance of my tests?
To improve test performance, consider running tests in parallel, using mocks for external dependencies, and optimizing your test setup.
