You can run a single test, a set of tests or all tests. Tests can be run on one browser or multiple browsers. By default tests are run in a headless manner meaning no browser window will be opened while running the tests and results will be seen in the terminal.

For a better debugging experience check out the [VS Code Extension](./getting-started-vscode.md) for Playwright where you can run tests, add breakpoints and debug your tests right from the VS Code editor.
npx playwright test landing-page.ts --project=chromium
```
## Debugging Tests
Since Playwright runs in Node.js, you can debug it with your debugger of choice e.g. using `console.log` or inside your IDE or directly in VS Code with the [VS Code Extension](./getting-started-vscode.md). Playwright comes with the [Playwright Inspector](./debug.md#playwright-inspector) which allows you to step through Playwright API calls, see their debug logs and explore [selectors](./selectors.md).
- Debugging all tests:
```bash
npx playwright test --debug
```
- Debugging one test file:
```bash
npx playwright test example.spec.ts --debug
```
- Debugging a test from the line number where the `test(..` is defined:
Check out our [debugging guide](./debug.md) to learn more about the [Playwright Inspector](./debug.md#playwright-inspector) as well as debugging with [Browser Developer tools](./debug.md#browser-developer-tools).
The [HTML Reporter](./html-reporter.md) shows you a full report of your tests allowing you to filter the report by browsers, passed tests, failed tests, skipped tests and flaky tests. You can click on each test and explore the tests errors as well as each step of the test. By default, the HTML report is opened automatically if some of the tests failed.
