saveScreenshot

Save a screenshot as a base64 encoded PNG with the current state of the browser. Be aware that some Selenium driver are taking screenshots of the whole document (e.g. phantomjs) and others only of the current viewport. If you want to always be sure that the screenshot has the size of the whole document, use wdio-screenshot to enhance this command with that functionality.

Usage

1
browser.saveScreenshot([filename]);
