--- id: test-cli title: "Command Line" --- ```sh # Ask for help! 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](./test-configuration.md). 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 ` or `--config `: Configuration file. If not passed, defaults to `playwright.config.ts` or `playwright.config.js` in the current directory. - `-c ` or `--config `: Directory with the tests to run without configuration file. - `--forbid-only`: Whether to disallow `test.only`. Useful on CI. - `-g ` or `--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 `: 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 ` or `-x`: Stop after the first `N` test failures. Passing `-x` stops after the first failure. - `--output `: Directory for artifacts produced by tests, defaults to `test-results`. - `--project `: Only run tests from one of the specified [projects](./test-advanced.md#projects). Defaults to running all projects defined in the configuration file. - `--quiet`: Whether to suppress stdout and stderr from the tests. - `--repeat-each `: Run each test `N` times, defaults to one. - `--reporter `: Choose a reporter: minimalist `dot`, concise `line` or detailed `list`. See [reporters](./test-reporters.md) for more information. - `--retries `: The maximum number of [retries](./test-retries.md) for flaky tests, defaults to zero (no retries). - `--shard `: [Shard](./test-parallel.md#shards) tests and execute only selected shard, specified in the form `current/all`, 1-based, for example `3/5`. - `--timeout `: Maximum timeout in milliseconds for each test, defaults to 10 seconds. - `--update-snapshots` or `-u`: Whether to update [snapshots](./test-snapshots.md) with actual results instead of comparing them. Use this when snapshot expectations have changed. - `--workers ` or `-j `: The maximum number of concurrent worker processes that run in [parallel](./test-parallel.md).
