Reference

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

OptionDescription
Non-option argumentsEach argument is treated as a regular expression matched against the full test file path. Only tests from the files matching the pattern will be executed. Special symbols like $ or * should be escaped with \. In many shells/terminals you may need to quote the arguments.
-c <file> or --config <file>Configuration file. If not passed, defaults to playwright.config.ts or playwright.config.js in the current directory.
--debugRun tests with Playwright Inspector. Shortcut for PWDEBUG=1 environment variable and --timeout=0 --max-failures=1 --headed --workers=1 options.
--forbid-onlyWhether to disallow test.only. Useful on CI.
--global-timeout <number>Total timeout for the whole test run in milliseconds. By default, there is no global timeout. Learn more about various timeouts.
-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". The regular expression will be tested against the string that consists of the test file name, test.describe titles if any, test title and all test tags, separated by spaces, e.g. my-test.spec.ts my-suite my-test @smoke. The filter does not apply to the tests from dependcy projects, i.e. Playwright will still run all tests from project dependencies.
--grep-invert <grep>Only run tests not matching this regular expression. The opposite of --grep. The filter does not apply to the tests from dependcy projects, i.e. Playwright will still run all tests from project dependencies.
--headedRun tests in headed browsers. Useful for debugging.
--ignore-snapshotsWhether to ignore snapshots. Use this when snapshot expectations are known to be different, e.g. running tests on Linux against Windows screenshots.
--last-failedOnly re-run the failures.
--listlist all the tests, but do not run them.
--max-failures <N> or -xStop after the first N test failures. Passing -x stops after the first failure.
--no-depsIgnore the dependencies between projects and behave as if they were not specified.
--output <dir>Directory for artifacts produced by tests, defaults to test-results.
--pass-with-no-testsAllows the test suite to pass when no files are found.
--project <name>Only run tests from the specified projects, supports '*' wildcard. Defaults to running all projects defined in the configuration file.
--quietWhether 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. You can also pass a path to a custom reporter file.
--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.
--tag <tag>Only run tests with a tag matching this tag expression. Learn more about tagging.
--timeout <number>Maximum timeout in milliseconds for each test, defaults to 30 seconds. Learn more about various timeouts.
--trace <mode>Force tracing mode, can be on, off, on-first-retry, on-all-retries, retain-on-failure
--update-snapshots or -uWhether 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.
