Note

Source: Python-specific — no direct equivalent in the C# edition. Questions cover pytest conventions, assert usage, and testing strategy.

1. What naming convention must a test file follow for pytest to discover it automatically?

2. What naming convention must a test function follow?

3. What happens when an assert statement fails inside a test function?

4. Write a test function that verifies abs(-5) == 5.

5. pytest.raises.

   1. What does pytest.raises(ValueError) do?

   2. When would you use it?

6. What is the difference between a unit test and an integration test?

7. Give three examples of edge cases you should always consider when writing tests for a numeric function.

8. Why is it generally better to have one assertion per test function rather than many?

9. How do you run only the tests in a file called test_strings.py from the command line?

10. C# vs. Python testing.

    1. In the C# edition, what attribute marks a test method?

    2. What is the Python pytest equivalent?

    3. What replaces Assert.AreEqual in pytest?
