Version 1.12

🧟‍♂️ Introducing Playwright Trace Viewer

Playwright Trace Viewer is a new GUI tool that helps exploring recorded Playwright traces after the script ran. Playwright traces let you examine:

• page DOM before and after each Playwright action
• page rendering before and after each Playwright action
• browser network during script execution

Traces are recorded using the new [property: BrowserContext.tracing] API:

browser = chromium.launch()
context = browser.new_context()

# Start tracing before creating / navigating a page.
context.tracing.start(screenshots=True, snapshots=True)

page.goto("https://playwright.dev")

# Stop tracing and export it into a zip archive.
context.tracing.stop(path = "trace.zip")

Traces are examined later with the Playwright CLI:

playwright show-trace trace.zip

That will open the following GUI:
