# Tracing class
|
|
|
|
The Tracing class exposes the tracing audit interface.
|
|
|
|
#### 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
|
|
|
|
```ts
|
|
await page.tracing.start({path: 'trace.json'});
|
|
await page.goto('https://www.google.com');
|
|
await page.tracing.stop();
|
|
```
|
|
|
|
