Tracing

Tracing class

The Tracing class exposes the tracing audit interface.

Signature:

export declare class Tracing

Remarks

You can use tracing.start and tracing.stop to create a trace file which can be opened in Chrome DevTools or timeline viewer.

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the Tracing class.

Example

await page.tracing.start({path: 'trace.json'});
await page.goto('https://www.google.com');
await page.tracing.stop();

Methods

Method Modifiers Description
start(options) Starts a trace for the current page.
stop() Stops a trace started with the start method.
