Answer 1

Jython

import org.openqa.selenium.OutputType as OutputType
import org.apache.commons.io.FileUtils as FileUtils
import java.io.File as File
import org.openqa.selenium.firefox.FirefoxDriver as FirefoxDriver

self.driver = FirefoxDriver()
tempfile = self.driver.getScreenshotAs(OutputType.FILE)
FileUtils.copyFile(tempfile, File("C:\\screenshot.png"))
