Signature: ```typescript 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](https://chromedevtools.github.io/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 ```js await page.tracing.start({path: 'trace.json'}); await page.goto('https://www.google.com'); await page.tracing.stop(); ``` ## Properties | Property | Modifiers | Type | Description | | --- | --- | --- | --- | | [\_client](./puppeteer.tracing._client.md) | | [CDPSession](./puppeteer.cdpsession.md) | | | [\_path](./puppeteer.tracing._path.md) | | string | | | [\_recording](./puppeteer.tracing._recording.md) | | boolean | | ## Methods | Method | Modifiers | Description | | --- | --- | --- | | [start(options)](./puppeteer.tracing.start.md) | | Starts a trace for the current page. | | [stop()](./puppeteer.tracing.stop.md) | | Stops a trace started with the start method. |
