What are the best practices for writing assertions in tests?

When writing assertions, ensure they are clear, concise, and directly related to the expected outcome.

Can you give me an example of a good assertion?

Sure! Instead of asserting that a value is true, assert that it equals the expected value, like assertEqual(actual, expected).

How many assertions should I include in a single test?

It's best to keep it to one or two assertions per test to maintain clarity and focus on specific outcomes.

What should I avoid when writing assertions?

Avoid using vague assertions, like checking if a value is truthy. Be specific about what you're testing.
