Implementation

test('deployment smoke test passes', async ({ page, baseURL }) => {
  // Basic health check assertions
  await page.goto('/');
  await expect(page).not.toHaveTitle(/error
500
502
503/i);
  await expect(page.getByRole('main')).toBeVisible();

  // API health check
  const response = await page.request.get('/api/health');
  expect(response.status()).toBe(200);
  const health = await response.json();
  expect(health.status).toBe('healthy');
});

Run Tests

Frequently Asked Questions

What should a Playwright smoke test cover?

Homepage load, API health endpoint, authentication flow, and critical business feature availability.

How to run Playwright smoke tests after k8s deployment?

Add a post-deployment job in your CI pipeline that runs Playwright with the new pod's URL.

How to handle deployment rollouts in smoke tests?

Add retry logic or waitForURL with timeout to handle pods that are still starting up.

Can Playwright test Kubernetes readiness probe endpoints?

Yes, use page.request.get('/readyz') and assert 200 status to verify pod readiness.

How to integrate Playwright smoke tests with Argo CD?

Configure an Argo CD post-sync hook that runs Playwright tests and fails the sync if tests fail.
