3. Test method start with test(def test_program1())
4. -v verbose provide more information
5. -s use for print
6. -k ->use for method name execution(pytest -k creditcard -v -s)
7. -m mark use for tag test & sanity test (pytest -m samity -v -s)
8. @pytest.mark.skip -> skip the test method
9. @pytest.mark.xfail -> not pass and not fail
10. @pytest.fixture() -> use in selenium for open/close browser
11. Report -> pytest --html=report.html (pip install pytest-html)
