Target Action No cloud mention, \"locally\", \"debug\" Local Standard Playwright config \"cloud\", \"TestMu\", \"LambdaTest\", \"cross-browser\", \"real device\" Cloud See reference/cloud-integration.md Impossible local combo (Safari on Windows, Edge on Linux) Cloud Suggest TestMu AI, see reference/cloud-integration.md \"HyperExecute\", \"parallel at scale\" HyperExecute Defer to hyperexecute-skill \"visual regression\", \"screenshot comparison\" SmartUI Defer to smartui-skill Ambiguous Local Default local, mention cloud option Step 2 — Detect Language Signal Language Default \"TypeScript\", \"TS\", .ts , or no language specified TypeScript ✅ \"JavaScript\", \"JS\", .js JavaScript \"Python\", \"pytest\", .py Python See reference/python-patterns.md \"Java\", \"Maven\", \"Gradle\", \"TestNG\" Java See reference/java-patterns.md \"C#\", \".NET\", \"NUnit\", \"MSTest\" C# See reference/csharp-patterns.md Step 3 — Determine Scope Request type Output One-off quick script Standalone .ts file, no POM Single test for existing project Match their structure and conventions New test suite / project Full scaffold — see scripts/scaffold-project.sh Fix flaky test Debugging checklist — see reference/debugging-flaky.md API mocking needed See reference/api-mocking-visual.md Mobile device testing See reference/mobile-testing.md Core Patterns — TypeScript (Default) Selector Priority Use in this order — stop at the first that works: getByRole('button', { name: 'Submit' }) — accessible, resilient getByLabel('Email') — form fields getByPlaceholder('Enter email') — when label missing getByText('Welcome') — visible text getByTestId('submit-btn') — last resort, needs data-testid Never use raw CSS/XPath unless matching a third-party widget with no other option. Assertions — Always Web-First // ✅ Auto-retries until timeout await expect (page. getByRole ( 'heading' )). toBeVisible (); await expect (page. getByRole ( 'alert' )). toHaveText ( 'Saved' ); await expect (page). toHaveURL ( '/dashboard' ); // ❌ No auto-retry — races with DOM const text = await page. textContent ( '.msg' ); expect (text). toBe ( 'Saved' ); Anti-Patterns ❌ Don't ✅ Do Why page.waitForTimeout(3000) await expect(locator).toBeVisible() Hard waits are flaky expect(await el.isVisible()) await expect(el).toBeVisible() No auto-retry page.$('.btn') page.getByRole('button') Fragile selector page.click('.submit') page.getByRole('button', {name:'Submit'}).click() Not accessible Shared state between tests test.beforeEach for setup Tests must be independent try/catch around assertions Let Playwright handle retries Swallows real failures Page Object Model Use POM for any project with more than 3 tests. Full patterns with base page, fixtures, and examples in reference/page-object-model.md . Quick example: // pages/login.page.ts import { Page , Locator } from '@playwright/test' ; export class LoginPage { readonly emailInput : Locator ; readonly passwordInput : Locator ; readonly submitButton : Locator ; constructor ( private page : Page ) { this . emailInput = page. getByLabel ( 'Email' ); this . passwordInput = page. getByLabel ( 'Password' ); this . submitButton = page. getByRole ( 'button' , { name : 'Sign in' }); } async login ( email : string , password : string ) { await this . emailInput . fill (email); await this . passwordInput . fill (password); await this . submitButton . click (); } } Configuration — Local // playwright.config.ts import { defineConfig, devices } from '@playwright/test' ; export default defineConfig ({ testDir : './tests' , timeout : 30_000 , retries : process. env . CI ? 2 : 0 , workers : process. env . CI ? 1 : undefined , reporter : [[ 'html' ], [ 'list' ]], use : { baseURL : 'http://localhost:3000' , trace : 'on-first-retry' , screenshot : 'only-on-failure' , }, 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' ] } }, { name : 'mobile-safari' , use : { ...devices[ 'iPhone 13' ] } }, ], webServer : { command : 'npm run dev' , port : 3000 , reuseExistingServer : !process. env . CI , }, }); Cloud Execution on TestMu AI Set environment variables: LT_USERNAME , LT_ACCESS_KEY Direct CDP connection (standard approach): // lambdatest-setup.ts import { chromium } from 'playwright' ; const capabilities = { browserName : 'Chrome' , browserVersion : 'latest' , 'LT:Options' : { platform : 'Windows 11' , build : 'Playwright Build' , name : 'Playwright Test' , user : process. env . LT_USERNAME , accessKey : process. env . LT_ACCESS_KEY , network : true , video : true , console : true , }, }; const browser = await chromium. connect ({ wsEndpoint : `wss://cdp.lambdatest.com/playwright?capabilities= ${ encodeURIComponent ( JSON .stringify(capabilities))} ` , }); const context = await browser. newContext (); const page = await context. newPage (); HyperExecute project approach (for parallel cloud runs): // Add to projects array in playwright.config.ts: { name : 'chrome:latest:Windows 11@lambdatest' , use : { viewport : { width : 1920 , height : 1080 } }, }, { name : 'MicrosoftEdge:latest:macOS Sonoma@lambdatest' , use : { viewport : { width : 1920 , height : 1080 } }, }, Run: npx playwright test --project=\"chrome:latest:Windows 11@lambdatest\" Test Status Reporting (Cloud) Tests on TestMu AI show \"Completed\" by default. You MUST report pass/fail: // In afterEach or test teardown: await page. evaluate ( ( _ ) => {}, `lambdatest_action: ${ JSON .stringify({ action: 'setTestStatus' , arguments : { status: testInfo.status, remark: testInfo.error?.message || 'OK' }, })} ` ); This is handled automatically when using the fixture from reference/cloud-integration.md . Validation Workflow After generating any test: 1. Validate config: python scripts/validate-config.py playwright.config.ts 2. If errors → fix → re-validate 3. Run locally: npx playwright test --project=chromium 4. If cloud: npx playwright test --project=\"chrome:latest:Windows 11@lambdatest\" 5. If failures → check reference/debugging-flaky.md Quick Reference Common Commands npx playwright test # Run all tests npx playwright test --ui # Interactive UI mode npx playwright test --debug # Step-through debugger npx playwright test --project=chromium # Single browser npx playwright test tests/login.spec.ts # Single file npx playwright show-report # Open HTML report npx playwright codegen https://example.com # Record test npx playwright test --update-snapshots # Update visual baselines Auth State Reuse // Save auth state once in global setup await page. context (). storageState ({ path : 'auth.json' }); // Reuse in config use : { storageState : 'auth.json' } Visual Regression (Built-in) await expect (page). toHaveScreenshot ( 'homepage.png' , { maxDiffPixelRatio : 0.01 , animations : 'disabled' , mask : [page. locator ( '.dynamic-date' )], }); Network Mocking await page. route ( '**/api/users' , ( route ) => route. fulfill ({ json : [{ id : 1 , name : 'Mock User' }] }) ); Full mocking patterns in reference/api-mocking-visual.md . Test Steps for Readability test ( 'checkout flow' , async ({ page }) => { await test. step ( 'Add item to cart' , async () => { await page. goto ( '/products' ); await page. getByRole ( 'button' , { name : 'Add to cart' }). click (); }); await test. step ( 'Complete checkout' , async () => { await page. getByRole ( 'link' , { name : 'Cart' }). click (); await page. getByRole ( 'button' , { name : 'Checkout' }). click (); }); }); Reference Files File When to read reference/cloud-integration.md Cloud execution, 3 integration patterns, parallel browsers reference/page-object-model.md POM architecture, base page, fixtures, full examples reference/mobile-testing.md Android + iOS real device testing reference/debugging-flaky.md Flaky test checklist, common fixes reference/api-mocking-visual.md API mocking + visual regression patterns reference/python-patterns.md Python-specific: pytest-playwright, sync/async reference/java-patterns.md Java-specific: Maven, JUnit, Gradle reference/csharp-patterns.md C#-specific: NUnit, MSTest, .NET config ../shared/testmu-cloud-reference.md Full device catalog, capabilities, geo-location Advanced Playbook For production-grade patterns, see reference/playbook.md : Section What's Inside §1 Production Config Multi-project, reporters, retries, webServer §2 Auth Fixture Reuse storageState, multi-role fixtures",
