Start recording a trace before performing actions. At the end, stop tracing and save it to a file.
API for collecting and saving Playwright traces. Playwright traces can be opened in [Trace Viewer](../trace-viewer.md) after Playwright script runs.

```
context.tracing.stop(path = "trace.zip")
page.goto("https://playwright.dev")
page = context.new_page()
context.tracing.start(screenshots=True, snapshots=True)
```python sync

**Usage**

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

def start_chunk(name: nil, title: nil)

```
context.tracing.stop_chunk(path = "trace2.zip")
# Save a second trace file with different actions.
page.goto("http://example.com")
context.tracing.start_chunk()

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

page.goto("https://playwright.dev")
page = context.new_page()
context.tracing.start(screenshots=True, snapshots=True)
```python sync

**Usage**

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`].
def start_chunk(name: nil, title: nil)
  wrap_impl(@impl.start_chunk(name: unwrap_impl(name), title: unwrap_impl(title)))
end

def stop(path: nil)

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

def stop_chunk(path: nil)

Stop the trace chunk. See [`method: Tracing.startChunk`] for more details about multiple trace chunks.
def stop_chunk(path: nil)
  wrap_impl(@impl.stop_chunk(path: unwrap_impl(path)))
end
