What are the best practices for writing JUnit tests?
Some best practices for writing JUnit tests include: 1. Keep tests independent, 2. Use descriptive names, 3. Test one thing at a time, 4. Use assertions effectively, and 5. Maintain a clear structure.
Can you explain why it's important to keep tests independent?
Keeping tests independent ensures that the outcome of one test does not affect another. This makes it easier to identify failures and maintain the tests.
What do you mean by using descriptive names for tests?
Descriptive names help convey the purpose of the test clearly. For example, instead of naming a test 'test1', use 'shouldReturnTrueWhenInputIsValid'.
How can I effectively use assertions in my tests?
Use assertions to verify that the expected outcome matches the actual result. Be specific with your assertions to ensure clarity in what you're testing.
