## Tracing class
The Tracing class exposes the tracing audit interface.
<b>Signature:</b>
```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();
```
