TestingPlaywright là lựa chọn hiện đại cho E2E testing — cross-browser thực sự (Chromium/Firefox/WebKit), async/await native, parallel execution built-in, Trace Viewer cho debug CI failures.
- Playwright là E2E testing framework từ Microsoft, hỗ trợ Chromium, Firefox, WebKit (Safari) — cross-browser coverage thực sự.
- Parallel test execution built-in: test files chạy song song theo default, có thể config workers; Cypress Cloud tính thêm phí cho parallelization.
- Multiple tabs/contexts/pages: test multi-tab flows như OAuth popup, new window; browser contexts là isolated sessions (khác profiles).
- Page Object Model tự nhiên: Playwright khuyến khích tổ chức code theo POM pattern với class-based pages. await/async API: test code dùng standard async/await — dễ đọc và debug hơn Cypress command queue.
- Network interception: page.route('/api/', route => route.fulfill({ json: mockData })) — mạnh và flexible; page.waitForResponse() để wait cho specific API call.
- Locators: page.getByRole('button', { name: 'Submit' }), getByText(), getByTestId() — semantic locators như Testing Library, auto-retry built-in.
- Visual regression testing: expect(page).toHaveScreenshot() so sánh screenshots.
- Tracing: tạo trace.zip với screenshots, network logs, DOM snapshots — mở trong Playwright Trace Viewer để debug CI failures.
- Playwright Inspector: step-through test execution, pick locators từ browser.
- So với Cypress: Playwright có better multi-browser support và parallel execution; Cypress có better DX và debugging cho single-browser.
Playwright is the modern choice for E2E testing — true cross-browser (Chromium/Firefox/WebKit), native async/await, built-in parallel execution, and Trace Viewer for debugging CI failures.
- Playwright is an E2E testing framework from Microsoft, supporting Chromium, Firefox, and WebKit (Safari) — true cross-browser coverage.
- Built-in parallel test execution: test files run in parallel by default, with configurable workers; Cypress Cloud charges extra for parallelization.
- Multiple tabs/contexts/pages: supports testing multi-tab flows such as OAuth popups and new windows; browser contexts are isolated sessions (like separate profiles).
- Page Object Model (POM) comes naturally: Playwright encourages organizing code by POM pattern with class-based pages. async/await API: test code uses standard async/await — more readable and easier to debug than Cypress's command queue.
- Network interception: page.route('/api/', route => route.fulfill({ json: mockData })) — powerful and flexible; page.waitForResponse() to wait for a specific API call.
- Locators: page.getByRole('button', { name: 'Submit' }), getByText(), getByTestId() — semantic locators like Testing Library, with built-in auto-retry.
- Visual regression testing: expect(page).toHaveScreenshot() compares screenshots.
- Tracing: generates a trace.zip with screenshots, network logs, and DOM snapshots — open in Playwright Trace Viewer to debug CI failures.
- Playwright Inspector: step through test execution, pick locators from the browser.
- Compared to Cypress: Playwright has better multi-browser support and parallel execution; Cypress has better DX and debugging for single-browser setups.
