typescript
import { Page, Locator } from '@playwright/test'
export class ItemsPage {
readonly page: Page
readonly searchInput: Locator
readonly itemCards: Locator
readonly createButton: Locator
constructor(page: Page) {
this.page = page
this.searchInput = page.locator('[data-testid="search-input"]')
this.itemCards = page.locator('[data-testid="item-card"]')
this.createButton = page.locator('[data-testid="create-btn"]')
}
async goto() {
await this.page.goto('/items')
await this.page.waitForLoadState('networkidle')
}
async search(query: string) {
await this.searchInput.fill(query)
await this.page.waitForResponse(resp => resp.url().includes('/api/search'))
await this.page.waitForLoadState('networkidle')
}
async getItemCount() {
return await this.itemCards.count()
}
}Test Structure
typescript
import { test, expect } from '@playwright/test'
import { ItemsPage } from '../../pages/ItemsPage'
test.describe('Item Search', () => {
let itemsPage: ItemsPage
test.beforeEach(async ({ page }) => {
itemsPage = new ItemsPage(page)
await itemsPage.goto()
})
test('should search by keyword', async ({ page }) => {
await itemsPage.search('test')
const count = await itemsPage.getItemCount()
expect(count).toBeGreaterThan(0)
await expect(itemsPage.itemCards.first()).toContainText(/test/i)
await page.screenshot({ path: 'artifacts/search-results.png' })
})
test('should handle no results', async ({ page }) => {
await itemsPage.search('xyznonexistent123')
await expect(page.locator('[data-testid="no-results"]')).toBeVisible()
expect(await itemsPage.getItemCount()).toBe(0)
})
})Playwright Configuration
typescript
import { defineConfig, devices } from '@playwright/test'
export default defineConfig({
testDir: './tests/e2e',
fullyParallel: true,
forbidOnly: !!process.env.CI,
retries: process.env.CI ? 2 : 0,
workers: process.env.CI ? 1 : undefined,
reporter: [
['html', { outputFolder: 'playwright-report' }],
['junit', { outputFile: 'playwright-results.xml' }],
['json', { outputFile: 'playwright-results.json' }]
],
use: {
baseURL: process.env.BASE_URL || 'http://localhost:3000',
trace: 'on-first-retry',
screenshot: 'only-on-failure',
video: 'retain-on-failure',
actionTimeout: 10000,
navigationTimeout: 30000,
},
projects: [
{ name: 'chromium', use: { ...devices['Desktop Chrome'] } },
{ name: 'firefox', use: { ...devices['Desktop Firefox'] } },
{ name: 'webkit', use: { ...devices['Desktop Safari'] } },
{ name: 'mobile-chrome', use: { ...devices['Pixel 5'] } },
],
webServer: {
command: 'npm run dev',
url: 'http://localhost:3000',
reuseExistingServer: !process.env.CI,
timeout: 120000,
},
})Flaky Test Patterns
Quarantine
typescript
test('flaky: complex search', async ({ page }) => {
test.fixme(true, 'Flaky - Issue #123')
// test code...
})
test('conditional skip', async ({ page }) => {
test.skip(process.env.CI, 'Flaky in CI - Issue #123')
// test code...
})Identify Flakiness
bash
npx playwright test tests/search.spec.ts --repeat-each=10
npx playwright test tests/search.spec.ts --retries=3Common Causes & Fixes
Race conditions:
typescript
// Bad: assumes element is ready
await page.click('[data-testid="button"]')
// Good: auto-wait locator
await page.locator('[data-testid="button"]').click()Network timing:
typescript
// Bad: arbitrary timeout
await page.waitForTimeout(5000)
// Good: wait for specific condition
await page.waitForResponse(resp => resp.url().includes('/api/data'))Animation timing:
typescript
// Bad: click during animation
await page.click('[data-testid="menu-item"]')
// Good: wait for stability
await page.locator('[data-testid="menu-item"]').waitFor({ state: 'visible' })
await page.waitForLoadState('networkidle')
await page.locator('[data-testid="menu-item"]').click()Artifact Management
Screenshots
typescript
await page.screenshot({ path: 'artifacts/after-login.png' })
await page.screenshot({ path: 'artifacts/full-page.png', fullPage: true })
await page.locator('[data-testid="chart"]').screenshot({ path: 'artifacts/chart.png' })Traces
typescript
await browser.startTracing(page, {
path: 'artifacts/trace.json',
screenshots: true,
snapshots: true,
})
// ... test actions ...
await browser.stopTracing()Video
typescript
// In playwright.config.ts
use: {
video: 'retain-on-failure',
videosPath: 'artifacts/videos/'

await page.waitForResponse(
resp => resp.url().includes('/api/trade') && resp.status() === 200,
