What are the best practices for using assertion libraries in testing?

When using assertion libraries, it's important to choose one that fits your testing framework. Also, ensure your assertions are clear and descriptive.

Can you give me examples of clear assertions?

Sure! Instead of using vague assertions like assertTrue(condition), use assertEquals(expected, actual) to clearly show what you're testing.

How do I handle multiple assertions in a single test?

It's best to keep tests focused on a single behavior. If you need multiple assertions, consider breaking them into separate tests for clarity.

What should I avoid when writing assertions?

Avoid using hard-coded values in assertions, as they can make tests brittle. Instead, use variables or constants that reflect the expected state.
