  ```bash
  npx playwright test tests/todo-page.spec.ts
  ```

- Run a set of test files
  ```bash
  npx playwright test tests/todo-page/ tests/landing-page/
  ```

- Run files that have `my-spec` or `my-spec-2` in the file name
  ```bash
  npx playwright test my-spec my-spec-2
  ```

- Run tests that are in line 42 in my-spec.ts
  ```bash
  npx playwright test my-spec.ts:42
  ```

- Run the test with the title
  ```bash
  npx playwright test -g "add a todo item"
  ```

- Run tests in headed browsers
  ```bash
  npx playwright test --headed
  ```

- Run all the tests against a specific project
  ```bash
  npx playwright test --project=chromium
  ```

- Disable [parallelization](./test-parallel.md)
  ```bash
  npx playwright test --workers=1
  ```

- Choose a [reporter](./test-reporters.md)
  ```bash
  npx playwright test --reporter=dot
  ```

- Run in debug mode with [Playwright Inspector](./debug.md)

## Reference

Complete set of Playwright Test options is available in the [configuration file](./test-use-options.md). Following options can be passed to a command line and take priority over the configuration file:

<!-- // Note: packages/playwright/src/program.ts is the source of truth. -->

| Option | Description |
| :- | :- |
| Non-option arguments | Each argument is treated as a regular expression matched against the full test file path. Only tests from 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, or a test directory with optional "playwright.config.{m,c}?{js,ts}". Defaults to `playwright.config.ts` or `playwright.config.js` in the current directory. |
| `--debug` | Run tests with Playwright Inspector. Shortcut for `PWDEBUG=1` environment variable and `--timeout=0 --max-failures=1 --headed --workers=1` options. |
| `--fail-on-flaky-tests` | Fail if any test is flagged as flaky (default: false). |
| `--forbid-only` | Fail if `test.only` is called (default: false). Useful on CI. |
| `--fully-parallel` | Run all tests in parallel (default: false). |
| `--global-timeout <timeout>` | Maximum time this test suite can run in milliseconds (default: unlimited). |
| `-g <grep>` or `--grep <grep>` | Only run tests matching this regular expression (default: ".*"). |
| `-gv <grep>` or `--grep-invert <grep>` | Only run tests that do not match this regular expression. |
| `--headed` | Run tests in headed browsers (default: headless). |
| `--ignore-snapshots` | Ignore screenshot and snapshot expectations. |
| `--last-failed` | Only re-run the failures. |
| `--list` | Collect all the tests and report them, but do not run. |
| `--max-failures <N>` or `-x` | Stop after the first `N` failures. Passing `-x` stops after the first failure. |
| `--no-deps` | Do not run project dependencies. |
| `--output <dir>` | Folder for output artifacts (default: "test-results"). |
| `--only-changed [ref]` | Only run test files that have been changed between 'HEAD' and 'ref'. Defaults to running all uncommitted changes. Only supports Git. |
| `--pass-with-no-tests` | Makes test run succeed even if no tests were found. |
| `--project <project-name...>` | Only run tests from the specified list of projects, supports '*' wildcard (default: run all projects). |
| `--quiet` | Suppress stdio. |
| `--repeat-each <N>` | Run each test `N` times (default: 1). |
| `--reporter <reporter>` | Reporter to use, comma-separated, can be "dot", "line", "list", or others (default: "list"). You can also pass a path to a custom reporter file. |
| `--retries <retries>` | Maximum retry count for flaky tests, zero for no retries (default: no retries). |
| `--shard <shard>` | Shard tests and execute only the selected shard, specified in the form "current/all", 1-based, e.g., "3/5". |
| `--timeout <timeout>` | Specify test timeout threshold in milliseconds, zero for unlimited (default: 30 seconds). |
| `--trace <mode>` | Force tracing mode, can be "on", "off", "on-first-retry", "on-all-retries", "retain-on-failure", "retain-on-first-failure". |
| `--tsconfig <path>` | Path to a single tsconfig applicable to all imported files (default: look up tsconfig for each imported file separately). |
| `--ui` | Run tests in interactive UI mode. |
| `--ui-host <host>` | Host to serve UI on; specifying this option opens UI in a browser tab. |
| `--ui-port <port>` | Port to serve UI on, 0 for any free port; specifying this option opens UI in a browser tab. |
| `-u` or `--update-snapshots [mode]` | Update snapshots with actual results. Possible values are "all", "changed", "missing", and "none". Not passing defaults to "missing"; passing without a value defaults to "changed". |
| `-j <workers>` or `--workers <workers>` | Number of concurrent workers or percentage of logical CPU cores, use 1 to run in a single worker (default: 50%). |
| `-x` | Stop after the first failure. |
