Accepted Answer

### Running a Single Test in Headed Mode

To run a single test in headed mode with @playwright/test, you can use the command line and the `.only` annotation. Running tests in headed mode is useful for debugging purposes.

First, add the `.only` annotation to the specific test case you want to run:

```typescript
test.only('should display the correct title', async ({ page }) => {
  await page.goto('https://ray.run/');
  const title = await page.title();
  expect(title).toBe('Ray.run');
});
```

Next, run the test file in headed mode using the following command:

```bash
npx playwright test your-test-file.spec.ts --headed
```

Replace `your-test-file.spec.ts` with the name of your test file.

If you want to specify a browser, use the `--browser` option followed by "chromium", "firefox", or "webkit":

```bash
npx playwright test your-test-file.spec.ts --headed --browser=chromium
```

This command will open Chromium with the specified test, allowing you to debug more easily.

By using the `.only` annotation and the `--headed` option, you can run a single test case in headed mode with @playwright/test.
