Playwright has some interesting CLI options for the regular npx playwright test command. Today I learned about the --grep and --grep-invert options. They both search for a regex in the test names and test tags. the --grep runs all tests matching the regex and --grep-invert runs all tests that don’t match the regex. Pretty cool!
