name: E2E Test Builder description: Create Playwright E2E tests using Page Object Model pattern with database isolation

E2E Test Builder

Use this skill when creating Playwright end-to-end tests for this project.

When to Use

• Adding tests for a new feature
• Testing user flows (authentication, content submission, admin actions)
• Validating UI interactions and navigation

Key Concepts

Database Isolation

Each test file gets its own isolated database copy:

• Call setupDatabaseIsolation(page) in beforeEach
• Auto-detects test file name from stack trace
• Ensures complete test independence

Page Object Model (POM)

All tests use POMs to encapsulate page interactions:

• POMs live in tests/pages/
• Extend BasePage for common functionality
• Use data-testid attributes for element selection

Test Users

Three users with different permission levels:

• admin - Full access (use for admin tests)
• contributor - Moderator role (can moderate content)
• viewer - Member role (read-only access)

Quick Start

import { test, expect } from '@playwright/test'
import { HomePage, ContentListPage } from '../../pages'
import { setupDatabaseIsolation } from '../../helpers/database-isolation'
import { loginAs } from '../../helpers/auth'

test.describe('My Feature', () => {
    test.beforeEach(async ({ page }) => {
        await setupDatabaseIsolation(page)
        await loginAs(page, 'admin') // if auth needed
    })

    test('can do something', async ({ page }) => {
        const homePage = new HomePage(page)
        await homePage.goto()
        // ... test logic
    })
})
