Is it possible to take screenshots using selenium grid 2? The RemoteWebDriver class does not implement the TakesScreenshot interface.

The RemoteWebDriver
must be augmented before you can use the screenshot capability. As you have no doubt already found, attempting to cast without augmenting results in an exception.
WebDriver driver = new RemoteWebDriver( ... );
driver = new Augmenter().augment( driver );
( (TakesScreenshot)driver ).getScreenshotAs( ... );
其他提示
You would need to write a wrapper class that extends RemoteWebDriver and implement TakeScreenshot interface something like below in java.
public class ScreenShotRemoteWebDriver extends RemoteWebDriver implements TakesScreenshot
{
public ScreenShotRemoteWebDriver(URL url, DesiredCapabilities dc) {
super(url, dc);
}
@Override
public <X> X getScreenshotAs(OutputType<X> target) throws WebDriverException {
if ((Boolean)getCapabilities().getCapability(CapabilityType.TAKES_SCREENSHOT)) {
return target.convertFromBase64Png(execute(DriverCommand.SCREENSHOT).getValue().toString());
}
return null;
}
}
