你可以使用Webdriverclass对象创建一个webdriver支持的selenium对象，然后你可以截屏。

JavaScript (Selenium-Webdriver)

driver.takeScreenshot().then(function(data){
   var base64Data = data.replace(/^data:image\/png;base64,/,"")
   fs.writeFile("out.png", base64Data, 'base64', function(err) {
        if(err) console.log(err);
   });
});

c#代码

IWebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((ITakesScreenshot)driver).GetScreenshotAs(OutputType.FILE);

// Now you can do whatever you need to do with it, for example copy somewhere
FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));

import java.io.File;
import java.io.IOException;

import org.apache.maven.surefire.shade.org.apache.maven.shared.utils.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
/**

public class ScreenShotMaker {

    // take screen shot on the test failures
    public void takeScreenShot(WebDriver driver, String fileName) {
        File screenShot = ((TakesScreenshot) driver)
                .getScreenshotAs(OutputType.FILE);
        try {
            FileUtils.copyFile(screenShot, new File("src/main/webapp/screen-captures/" + fileName + ".png"));

        } catch (IOException ioe) {
            throw new RuntimeException(ioe.getMessage(), ioe);
        }
    }

}

Java

是的，这是可能的。下面以Java为例:

WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
// Now you can do whatever you need to do with it, for example copy somewhere
FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));

Ruby(黄瓜)

After do |scenario| 
    if(scenario.failed?)
        puts "after step is executed"
    end
    time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M')

    file_path = File.expand_path(File.dirname(__FILE__) + '/../../../../../mlife_screens_shot')+'/'+time +'.png'

    page.driver.browser.save_screenshot file_path
end

Given /^snapshot$/ do
    time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M')

    file_path = File.expand_path(File.dirname(__FILE__) + '/../../../../../mlife_screens_shot')+'/'+time +'.png'
    page.driver.browser.save_screenshot file_path
end
