Defined in:

Overview

API for collecting and saving Playwright traces. Playwright traces can be opened in [Trace Viewer](./trace-viewer.md) after Playwright script runs.

Start recording a trace before performing actions. At the end, stop tracing and save it to a file.

“‘python sync browser = chromium.launch() context = browser.new_context() context.tracing.start(screenshots=True, snapshots=True) page = context.new_page() page.goto(“playwright.dev”) context.tracing.stop(path = “trace.zip”) “`

Instance Method Details

#start(name: nil, screenshots: nil, snapshots: nil) ⇒ Object

Start tracing.

“‘python sync context.tracing.start(name=“trace”, screenshots=True, snapshots=True) page = context.new_page() page.goto(“playwright.dev”) context.tracing.stop(path = “trace.zip”) “`

def start(name: nil, screenshots: nil, snapshots: nil)
  wrap_impl(@impl.start(name: unwrap_impl(name), screenshots: unwrap_impl(screenshots), snapshots: unwrap_impl(snapshots)))
end

#start_chunk ⇒ Object

Start a new trace chunk. If you’d like to record multiple traces on the same ‘BrowserContext`, use

‘method: Tracing.start`

once, and then create multiple trace chunks with [‘method: Tracing.startChunk`] and

[‘method: Tracing.stopChunk`].

“‘python sync context.tracing.start(name=“trace”, screenshots=True, snapshots=True) page = context.new_page() page.goto(“playwright.dev”)

context.tracing.start_chunk() page.click(“text=Get Started”) # Everything between start_chunk and stop_chunk will be recorded in the trace. context.tracing.stop_chunk(path = “trace1.zip”)

context.tracing.start_chunk() page.goto(“example.com”) # Save a second trace file with different actions. context.tracing.stop_chunk(path = “trace2.zip”) “‘

def stop(path: nil)
  wrap_impl(@impl.stop(path: unwrap_impl(path)))
end

#stop_chunk(path: nil) ⇒ Object

Stop the trace chunk. See [‘method: Tracing.startChunk`] for more details about multiple trace chunks.
