Reference

Complete set of Playwright Test options is available in the configuration file. Following options can be passed to a command line and take a priority over the configuration file:

--headed: Run tests in headed browsers. Useful for debugging.
--browser: Run test in a specific browser. Available options are "chromium", "firefox", "webkit" or "all" to run tests in all three browsers at the same time.
--debug: Run tests with Playwright Inspector. Shortcut for PWDEBUG=1 environment variable and --timeout=0 --max-failures=1 --headed --workers=1 options.
-c <file> or --config <file>: Configuration file. If not passed, defaults to playwright.config.ts or playwright.config.js in the current directory.
-c <dir> or --config <dir>: Directory with the tests to run without configuration file.
--forbid-only: Whether to disallow test.only. Useful on CI.
-g <grep> or --grep <grep>: Only run tests matching this regular expression. For example, this will run 'should add to cart' when passed -g "add to cart".
--grep-invert <grep>: Only run tests not matching this regular expression. The opposite of --grep.
--global-timeout <number>: Total timeout for the whole test run in milliseconds. By default, there is no global timeout. Learn more about various timeouts.
--list: List all the tests, but do not run them.
--max-failures <N> or -x: Stop after the first N test failures. Passing -x stops after the first failure.
--output <dir>: Directory for artifacts produced by tests, defaults to test-results.
--project <name>: Only run tests from one of the specified projects. Defaults to running all projects defined in the configuration file.
--quiet: Whether to suppress stdout and stderr from the tests.
--repeat-each <N>: Run each test N times, defaults to one.
--reporter <reporter>: Choose a reporter: minimalist dot, concise line or detailed list. See reporters for more information.
--retries <number>: The maximum number of retries for flaky tests, defaults to zero (no retries).
--shard <shard>: Shard tests and execute only selected shard, specified in the form current/all, 1-based, for example 3/5.
--timeout <number>: Maximum timeout in milliseconds for each test, defaults to 30 seconds. Learn more about various timeouts.
--ignore-snapshots or -i: Whether to ignore snapshots. Use this when snapshot expectations are known to be different, e.g. running tests on Linux against Windows screenshots.
--update-snapshots or -u: Whether to update snapshots with actual results instead of comparing them. Use this when snapshot expectations have changed.
--workers <number> or -j <number>: The maximum number of concurrent worker processes that run in parallel.
