Playwright E2E Testing

Visual testing workflow for the Strieber chat UI frontend.

When to Use

After making changes to:

• Svelte components (frontend/src/**/*.svelte)
• CSS/styles (frontend/src/app.css, Tailwind classes)
• Layout structure
• Any visible UI element

Run Tests

Copydocker compose run --rm playwright-test

This builds the production bundle and runs Playwright tests in headless Chromium.

View Screenshots

After tests complete, read the screenshots:

Copyfrontend/test-results/screenshots/layout-desktop.png  # 1280x720 desktop view
frontend/test-results/screenshots/layout-mobile.png   # 375x667 mobile view

Use the Read tool on these PNG files to visually verify the UI.

Verification Checklist

1. Layout renders correctly (sidebar, main area)
2. Colors/theme applied properly
3. Responsive behavior works (mobile hides sidebar)
4. No visual regressions from previous state
5. Text is readable and properly positioned

Adding New Tests

Create tests in frontend/e2e/<feature>.spec.ts:

Copyimport { test, expect } from '@playwright/test';

test('my feature test', async ({ page }) => {
  await page.goto('/');

  // Take screenshot for visual verification
  await page.screenshot({
    path: 'test-results/screenshots/my-feature.png',
    fullPage: true
  });

  // Add assertions
  await expect(page.locator('.my-element')).toBeVisible();
});
