export default defineConfig({

    video: 'on',
  },
  projects: [
    {
      name: 'chromium',
      use: { ...devices['Desktop Chrome'], },
    },
});

Test file (self-contained)

it('should show the testid in trace', async ({ page }) => {
  await page.setContent(`<input id='checkbox' type='checkbox' data-testid='test-hello'></input>`);
  await expect(page.getByTestId(/test-hello/)).toBeVisible();
});

Steps

Actual

Select the assertion step in the trace file and click "Call". Observe the parameter section. locator: getByTestId('') is displayed.
