C#

public static void TakeScreenshot(IWebDriver driver, String filename)
{
    // Take a screenshot and save it to filename
    Screenshot screenshot = ((ITakesScreenshot)driver).GetScreenshot();
    screenshot.SaveAsFile(filename, ImageFormat.Png);
}

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。

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);
    }

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# （Ranorex API）

public static void ClickButton()
{
    try
    {
        // code
    }
    catch (Exception e)
    {
        TestReport.Setup(ReportLevel.Debug, "myReport.rxlog", true);
        Report.Screenshot();
        throw (e);
    }
}

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"));
