Java

public String captureScreen() {
    String path;
    try {
        WebDriver augmentedDriver = new Augmenter().augment(driver);
        File source = ((TakesScreenshot)augmentedDriver).getScreenshotAs(OutputType.FILE);
        path = "./target/screenshots/" + source.getName();
        FileUtils.copyFile(source, new File(path)); 
    }
    catch(IOException e) {
        path = "Failed to capture screenshot: " + e.getMessage();
    }
    return path;
}

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);
}

C#

你可以使用下面的代码片段/函数用Selenium截图:

    public void TakeScreenshot(IWebDriver driver, string path = @"output")
    {
        var cantakescreenshot = (driver as ITakesScreenshot) != null;
        if (!cantakescreenshot)
            return;
        var filename = string.Empty + DateTime.Now.Hour + DateTime.Now.Minute + DateTime.Now.Second + DateTime.Now.Millisecond;
        filename = path + @"\" + filename + ".png";
        var ss = ((ITakesScreenshot)driver).GetScreenshot();
        var screenshot = ss.AsBase64EncodedString;
        byte[] screenshotAsByteArray = ss.AsByteArray;
        if (!Directory.Exists(path))
            Directory.CreateDirectory(path);
        ss.SaveAsFile(filename, ImageFormat.Png);
    }

Java

这里似乎没有-在Java中截取一个特定元素的截图:

public void takeScreenshotElement(WebElement element) throws IOException {
    WrapsDriver wrapsDriver = (WrapsDriver) element;
    File screenshot = ((TakesScreenshot) wrapsDriver.getWrappedDriver()).getScreenshotAs(OutputType.FILE);
    Rectangle rectangle = new Rectangle(element.getSize().width, element.getSize().height);
    Point location = element.getLocation();
    BufferedImage bufferedImage = ImageIO.read(screenshot);
    BufferedImage destImage = bufferedImage.getSubimage(location.x, location.y, rectangle.width, rectangle.height);
    ImageIO.write(destImage, "png", screenshot);
    File file = new File("//path//to");
    FileUtils.copyFile(screenshot, file);
}

Java

对于较新版本的Java, FileUtils函数不起作用。在这里，下面的功能可以完美地复制屏幕截图。

import java.io.File;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.io.FileHandler;

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
File destfile = new File(destination folder /filename.extension);
FileHandler.copy(scrfile, destfile);

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。
