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"))

Python

每个WebDriver都有一个. save_截图(filename)方法。所以对于Firefox，它可以这样使用:

from selenium import webdriver

browser = webdriver.Firefox()
browser.get('http://www.google.com/')
browser.save_screenshot('screenie.png')

令人困惑的是，.get_screenshot_as_file(filename)方法也存在，它做同样的事情。

还有一些方法:.get_screenshot_as_base64()(用于嵌入HTML)和.get_screenshot_as_png()(用于检索二进制数据)。

注意，WebElements有一个.截图()方法，它的工作原理类似，但只捕获所选元素。

我使用下面的c#代码来获取整个页面或仅一个浏览器截图

    public void screenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            ITakesScreenshot screen = driverScript.driver as ITakesScreenshot;
            Screenshot screenshot = screen.GetScreenshot();
            screenshot.SaveAsFile(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Fail see Exception", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside screenShot");
        }
    }

    public void fullPageScreenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            Rectangle bounds = Screen.GetBounds(Point.Empty);
            using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
            {
                using (Graphics g = Graphics.FromImage(bitmap))
                {
                    g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
                }
                bitmap.Save(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            }
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Pass", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside fullPageScreenShot");
        }
    }

C#

public Bitmap TakeScreenshot(By by) {
    // 1. Make screenshot of all screen
    var screenshotDriver = _selenium as ITakesScreenshot;
    Screenshot screenshot = screenshotDriver.GetScreenshot();
    var bmpScreen = new Bitmap(new MemoryStream(screenshot.AsByteArray));

    // 2. Get screenshot of specific element
    IWebElement element = FindElement(by);
    var cropArea = new Rectangle(element.Location, element.Size);
    return bmpScreen.Clone(cropArea, bmpScreen.PixelFormat);
}

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"));
