PyTest
summary
Shows how to use pytest from installation to diagnosis: install with pip install pytest (inside virtualenv), write plain assert tests, run selected cases with pytest file.py::test_name, and inspect rich failures where pytest pinpoints differing chars, list items or dict keys. Demonstrates marking flaky bugs with @pytest.mark.xfail(reason="bug id"), skipping with skip/skipif, flags (-s to show stdout, -q, -x, --maxfail), and simple fixtures like tmpdir for isolated file-system tests.
