💡 Quick Start: Follow these 1 steps in order to get up and running with Playwright quickly.
Explore the key features that make Playwright powerful for web & browser automation workflows.
Before executing any interaction, Playwright checks that the target element is attached to DOM, visible, not obscured, stable (not animating), and enabled. This layered check replaces manual sleep() calls and arbitrary retry logic, dramatically reducing flaky tests on modern SPAs.
A checkout flow test that previously required 15 sleep() calls across button clicks, form submissions, and page transitions runs reliably without any timing hacks — each action waits precisely until the element is ready.
Records a complete test execution trace including timestamped action log, before/after screenshots, DOM snapshots, network requests with full headers and bodies, console output, and source code mapping. Traces are viewed locally or in CI artifacts without reproductions.
A login test fails in CI on Tuesdays but not locally. The trace reveals a 200ms slower network response causing a race condition between two state updates — identified without any local reproduction attempt.
Interactive browser session records user actions (clicks, typing, navigation, assertions) and generates corresponding test code in TypeScript, JavaScript, Python, Java, or C#. Generated selectors use accessible attributes preferentially over XPath or CSS class selectors.
A QA engineer with limited coding experience records a 10-step checkout flow in 5 minutes. The generated Python code, with minor edits for parameterization, becomes the basis of a reusable test covering the critical payment path.
Each browser context is a fresh, isolated session equivalent to a private window — separate cookies, localStorage, indexedDB, and authentication state. Multiple contexts run concurrently within a single browser instance for efficiency.
A real-time collaboration test spins up two contexts (user A and user B), logs each into different accounts, and verifies that edits made by user A appear instantly for user B — all in one test without separate browser processes.
Intercepts, inspects, modifies, blocks, or mocks any network request. Supports response stubbing with custom status codes and bodies, request modification, rate limiting simulation, and waiting for specific requests before proceeding.
Test verifies error handling when a payment API returns 503: intercept the POST to /api/payments, return a mocked 503 response, and assert that the UI shows the correct retry prompt without requiring backend configuration changes.
Tests run in parallel across multiple workers by default (one per CPU core). Test suite sharding distributes files across multiple CI machines for further speedup. Reporters aggregate results from all shards into a single report.
A 600-test suite taking 18 minutes with serial execution completes in under 3 minutes using 8 shards on a CI platform — fitting within a 5-minute PR check budget without reducing test coverage.
Playwright offers better reliability through auto-wait functionality, faster execution, built-in cross-browser support, and modern architecture. Selenium has larger ecosystem and longer track record but requires more setup and maintenance. Playwright is generally recommended for new projects requiring reliable browser automation.
Yes, Playwright excels with SPAs through its auto-wait functionality that waits for DOM stability and network requests to complete. It handles React, Vue, Angular, and other frameworks well by waiting for JavaScript execution and DOM updates before proceeding with interactions.
Playwright can run tests in parallel across browsers, but this requires more system resources. Execution time typically scales with available CPU cores and memory. Running tests across 3 browsers in parallel might use 3x memory but complete in similar time as single-browser execution.
Excellent. Playwright provides official Docker images, integrates with all major CI platforms, and includes built-in reporters for test results. The headless execution and parallel testing capabilities make it ideal for automated testing pipelines with fast feedback loops.
Yes, the Codegen tool records user interactions and generates test code automatically. While technical knowledge helps for test maintenance and debugging, the recorded tests provide a starting point that can be refined by developers or technical team members.
Now that you know how to use Playwright, it's time to put this knowledge into practice.
