In this pytest tutorial, we covered the following areas −

• Installing pytest..
• Identifying test files and test functions.
• Executing all test files using pytest –v.
• Executing specific file usimng pytest <filename> -v.
• Execute tests by substring matching pytest -k <substring> -v.
• Execute tests based on markers pytest -m <marker_name> -v.
• Creating fixtures using @pytest.fixture.
• conftest.py allows accessing fixtures from multiple files.
• Parametrizing tests using @pytest.mark.parametrize.
• Xfailing tests using @pytest.mark.xfail.
• Skipping tests using @pytest.mark.skip.
• Stop test execution on n failures using pytest –maxfail = <num>.
• Running tests in parallel using pytest -n <num>.
• Generating results xml using pytest -v –junitxml = “result.xml”.
