我用这个方法来截图

public static void getScreenshot(WebDriver driver){
File screenshot=((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
String currentLocation=
System.getProperty("user.dir")+"/src/main/java/screenshots/";
//but you can put  your location
    try {
        FileUtils.copyFile(screenshot,
                new File(currentLocation + System.currentTimeMillis() + ".png"));
    }catch (IOException e){
        System.out.println("The screenshot was not taken");
        e.printStackTrace();
    }

}

字符串
