npx playwright test --help

Arguments passed to npx playwright test are treated as a filter for test files. For example, npx playwright test my-spec will only run tests from files with my-spec in the name.

All the options are available in the configuration file. However, selected 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.
  • -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".
  • --global-timeout <number>: Total timeout for the whole test run in milliseconds. By default, there is no global timeout.
  • --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.
  • --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.
