Unit Testing Best Practices

Unit testing is a crucial practice in software development that helps ensure code quality and reliability. Here are the lists of best practices for effective unit testing

1. Write descriptive and meaningful test names that explain what is being tested and the expected outcome. This serves as documentation and helps other developers understand the purpose of each test.
2. Keep tests simple and focused. Each test should verify a single behavior or functionality to make debugging easier and maintain test clarity.
3. In your unit tests, avoid dependencies on external systems or infrastructure. Isolate the code being tested with mocks or stubs.
4. Write minimally passing tests that verify the expected behavior without overcomplicating the test logic.
5. Ensure your tests are deterministic, meaning they produce the same results every time they run under the same conditions.
6. Use relevant and high-quality test data that covers various scenarios, including edge cases and potential error conditions.
7. Automate your unit tests to run them frequently, ideally as part of your continuous integration pipeline.
