Key Architectural Takeaways

  • Began by mapping critical user checkout and authentication journeys.
  • Avoided test flakiness by using data-test-id attributes on crucial selectors.
  • Configured Playwright parallel execution on GitHub self-hosted runners.
  • Added Slack reports with screenshots for any test failure in staging.

From 5 Days of Manual Testing to 4 Hours of Automation

An EdTech company was releasing features once every two weeks because staging testing required days of tedious manual validation. Any hotfix took hours of regression checking. We set up an automated testing framework to release developers from manual validation.

Sample Playwright Auth Test Script

Here is the structure we used to automate user login. We mock non-essential network dependencies to speed up execution and prevent test flakiness:

Sample Playwright Auth Test Script
import { test, expect } from '@playwright/test';

test.describe('Authentication Flows', () => {
  test('User should login successfully with valid credentials', async ({ page }) => {
    // Intercept and mock third-party analytics calls
    await page.route('**/analytics-tracker/**', route => route.abort());

    await page.goto('/login');
    
    // Fill credentials using robust test ids
    await page.fill('[data-testid="email-input"]', 'test.user@thinkalternate.com');
    await page.fill('[data-testid="password-input"]', 'SuperSecurePass123!');
    
    await page.click('[data-testid="submit-button"]');
    
    // Verify successful routing and state
    await expect(page).toHaveURL('/dashboard');
    await expect(page.locator('[data-testid="user-greeting"]')).toContainText('Hello, Test User');
  });
});
