Post-deployment smoke tests automated or documented; key user flows verified after every production deployment

A deployment that succeeds at the infrastructure level can still break login, payment processing, or core data flows — the CI/CD pipeline passes, but users hit errors. Without automated post-deployment smoke tests (NIST SA-11, SSDF PW.8), the first signal of a broken deployment is a user support ticket. ISO 25010 reliability.maturity requires that production changes be verified as correct after deployment, not just before it. A 3-minute automated smoke test covering the critical user journey is the difference between a 5-minute rollback and a 45-minute incident.

Add automated post-deployment smoke tests using Playwright. Run them immediately after the production deployment step in CI/CD.

npm install --save-dev @playwright/test

// tests/smoke.spec.ts
import { test, expect } from '@playwright/test';

test('homepage loads', async ({ page }) => {
  await page.goto(process.env.BASE_URL!);
  await expect(page).toHaveTitle(/my app/i);
});

test('login flow completes', async ({ page }) => {
  await page.goto(`${process.env.BASE_URL}/login`);
  await page.fill('[name=email]', process.env.SMOKE_TEST_EMAIL!);
  await page.fill('[name=password]', process.env.SMOKE_TEST_PASSWORD!);
  await page.click('[type=submit]');
  await expect(page).toHaveURL(/\/dashboard/);
});

# .github/workflows/deploy.yml
- name: Deploy to production
  run: npm run deploy:prod

- name: Run smoke tests
  run: npx playwright test tests/smoke.spec.ts
  env:
    BASE_URL: https://your-app.com
    SMOKE_TEST_EMAIL: ${{ secrets.SMOKE_TEST_EMAIL }}
    SMOKE_TEST_PASSWORD: ${{ secrets.SMOKE_TEST_PASSWORD }}

• ID: deployment-readiness.environment-configuration.smoke-tests

• Severity: info

• What to look for: Enumerate every relevant item. Look for post-deployment test scripts in CI/CD workflow (typically after deployment step). Check for documented smoke test procedures in README or DEPLOYMENT.md. Smoke tests should verify key user flows: login, core features, payment processing (if applicable).

• Pass criteria: Smoke tests are automated in the CI/CD pipeline after production deployment, OR documented and regularly executed. Tests verify critical user flows.

• Fail criteria: No smoke tests found, or tests exist but are not automated or documented.

• Skip (N/A) when: The project is API-only with no user flows.

• Detail on fail: "No smoke tests found after deployment step in CI/CD pipeline." or "Smoke test runbook exists but is not automated."

• Remediation: Add automated smoke tests. For Next.js with Playwright:

  npm install --save-dev @playwright/test
  

  Create tests/smoke.spec.ts:

  import { test, expect } from '@playwright/test';
  
  test.describe('Smoke Tests', () => {
    test('homepage loads and login visible', async ({ page }) => {
      await page.goto('https://your-app.com');
      await expect(page.locator('text=Login')).toBeVisible();
    });
  
    test('user can login', async ({ page }) => {
      await page.goto('https://your-app.com/login');
      await page.fill('input[name=email]', 'test@example.com');
      await page.fill('input[name=password]', 'password');
      await page.click('button[type=submit]');
      await expect(page).toHaveURL(/.*dashboard/);
    });
  });
  

  Then add to CI/CD after deployment:

  # .github/workflows/deploy.yml
  - name: Deploy to production
    run: npm run deploy:prod
  
  - name: Smoke tests
    run: npx playwright test tests/smoke.spec.ts
