What are some tips for debugging with pytest?

Here are some tips for debugging with pytest:

1. Use the -v option for verbose output.
2. Utilize --pdb to drop into the debugger on failure.
3. Leverage pytest --tb=short for concise traceback.
4. Use fixtures to isolate tests and manage state.

How can I use the --pdb option effectively?

The --pdb option allows you to enter the Python debugger when a test fails. Just run your tests with pytest --pdb, and when a failure occurs, you'll be dropped into an interactive debugging session where you can inspect variables and step through the code.

What does the -v option do?

The -v option stands for verbose mode. It provides detailed output for each test, showing which tests are being run and their results, making it easier to identify which tests are passing or failing.

Can you explain how to use fixtures in pytest?

Sure! Fixtures in pytest are functions that run before your tests to set up any state or context. You can define a fixture using the @pytest.fixture decorator and then pass it as an argument to your test functions.
