Playwright Trace Viewer Tutorial for Educational Students

Introduction to Playwright Trace Viewer


Debugging automation scripts can be difficult, especially when tests fail unexpectedly. Playwright Trace Viewer is a powerful debugging tool that helps testers replay every action performed during test execution. It allows students to view screenshots, logs, network requests, and browser actions step-by-step, making it easier to identify failures and improve automation skills. According to Playwright documentation, Trace Viewer enables developers and testers to inspect DOM snapshots, logs, and timelines for efficient debugging , and we offers practical training   in Playwright with AI for educational students.


What is Playwright Trace Viewer?


Playwright Trace Viewer is a GUI-based debugging feature in Playwright that records test execution into a trace.zip file. Students can replay tests visually and inspect what happened before and after each action. This feature is especially useful for debugging failed automation tests in CI/CD pipelines or local environments.


How to Enable Trace Viewer


To enable tracing in Playwright, students can configure trace settings inside the Playwright configuration file:


on-first-retry – Records trace only after first test retry

retain-on-failure – Saves traces only for failed tests

on – Records all test executions (may affect performance)


After execution, use the command:


npx playwright show-trace trace.zip


This opens the Trace Viewer where students can analyze failures visually.


Benefits for Educational Students


Educational students learning automation testing can improve debugging skills, reduce troubleshooting time, and better understand test failures using Trace Viewer. Community discussions also suggest that debugging artifacts like Trace Viewer significantly help in analyzing flaky tests faster.
