Complete Playwright Tutorial
What Is Playwright?
Playwright is a modern browser-automation framework known for speed, reliability, and built-in auto-waiting that eliminates much of the flakiness common in older tools. It handles UI, API, and network testing in one framework. This guide covers Playwright end to end, including how it compares to Selenium.
Part 1 — Fundamentals
- Playwright Fundamentals — architecture, setup, and your first test.
- Locators & Actions — modern locators and interacting with elements.
- Auto-Wait & Synchronization — built-in waiting and why Playwright is less flaky.
- UI Elements — forms, dropdowns, frames, and dialogs.
Part 2 — Validation & Test Runner
- Assertions & Screenshots — web-first assertions and visual capture.
- Test Runner — the Playwright Test runner, config, fixtures, and parallelism.
Part 3 — Advanced
- API & Network Testing — API requests and network interception/mocking.
- Authentication & Storage State — reusing login via storage state.
- Reporting & Debugging — reports, trace viewer, and debugging tools.
Part 4 — Scenarios & Comparison
- Scenario-Based Questions — real-world Playwright challenges.
- Comparisons & Architecture — Playwright vs Selenium and architectural differences.
How to Use This Guide
- Beginners: Parts 1 → 4 in order.
- Coming from Selenium: start with the comparison/architecture tutorial, then auto-wait and locators.
- Interview prep: scenario-based and comparison tutorials.
Pair with the Complete Selenium Guide to understand the trade-offs between the two.
Frequently Asked Questions
Is Playwright better than Selenium?
Playwright provides built-in auto-waiting, modern browser automation capabilities, integrated API testing, and a built-in test runner.
Selenium offers a mature ecosystem, broad language support, and extensive industry adoption.
Both frameworks have their strengths, and the comparison tutorial discusses their differences in detail.
Does Playwright require explicit waits?
In most situations, no.
Playwright automatically waits for elements to become ready before interacting with them, reducing the need for explicit synchronization.
Can Playwright perform API testing?
Yes.
Playwright includes built-in support for API requests, response validation, network interception, and request mocking.
How can I avoid logging in before every test?
Use Storage State to save an authenticated session and reuse it across multiple test executions.
How do I debug Playwright tests?
Playwright provides several debugging features, including:
- Trace Viewer
- Screenshots
- Reports
- Built-in debugging tools
These features help identify automation failures efficiently.
