saveScreenshot
Save a screenshot of the current browsing context to a PNG file on your OS. Be aware that some browser drivers take screenshots of the whole document (e.g. Geckodriver with Firefox) and others only of the current viewport (e.g. Chromedriver with Chrome).
Usage
browser.saveScreenshot(filepath)
Parameters
| Name | Type | Details | 
|---|---|---|
| filepath | String | path to the generated image ( .pngsuffix is required) relative to the execution directory |

it('should save a screenshot of the browser view', async () => {
    await browser.saveScreenshot('./some/path/screenshot.png');
