c# - 在 Selenium 2 中截取测试屏幕截图的最佳方法是什么？

Question

我需要一种方法来截取我的功能测试的屏幕截图。现在我正在使用带有 C# 绑定的 Selenium 2。我非常想在测试结束时截屏以确保显示所需的页面。你们知道我可以将哪些特定工具合并到我的 C# 代码中来触发屏幕截图吗？我找不到内置的 Selenium 2 解决方案（不仔细看）。

要在 Selenium 2 中进行屏幕截图，您需要执行以下操作

driver = new FireFoxDriver(); // Should work in other Browser Drivers
driver.Navigate().GoToUrl("http://www.theautomatedtester.co.uk");
Screenshot ss = ((ITakesScreenshot) driver).GetScreenshot();

//Use it as you want now
string screenshot = ss.AsBase64EncodedString;
byte[] screenshotAsByteArray = ss.AsByteArray;
ss.SaveAsFile("filename", ImageFormat.Png); //use any of the built in image formating
ss.ToString();//same as string screenshot = ss.AsBase64EncodedString;

该代码应该可以工作，因为我在 IronPython Repl 中快速对其进行了测试。请参阅下面的 IronPython 代码

import clr
clr.AddReference("WebDriver.Common.dll")
clr.AddReference("WebDriver.Firefox.dll")
from OpenQA.Selenium import *
from OpenQA.Selenium.Firefox import *
driver = FirefoxDriver()
driver.Navigate().GoToUrl("http://www.theautomatedtester.co.uk")
s = driver.GetScreenshot()
s.AsBaseEncodedString
# HUGE string appears in the REPL

var driver = new InternetExplorerDriver();
driver.Navigate().GoToUrl("http://www.google.com");
var ss = driver.GetScreenshot();   
ss.SaveAsFile("ss.png", System.Drawing.Imaging.ImageFormat.Png);

我不知道这是否重要，但是当我用 c# 编写代码时，我最终不得不强制转换驱动程序。

就像是：

截图 ss = ((ITakesScreenshot)driver).GetScreenshot();

只需在一行代码中使用扩展方法 TakeScreenshot() 即可。

IWebDriver driver = new InternetExplorerDriver();
driver.Navigate().GoToUrl("Your_Homepage_Url");

driver.TakeScreenshot().SaveAsFile("file_name_string", ImageFormat.Jpeg);

System.Drawing在您的解决方案/项目中添加参考。
System.Drawing.Imaging在测试中使用命名空间。

在这里，我正在捕获 Facebook 主页的屏幕截图。

        IWebElement element = null;

        public void SetUp()
        {

            driver.Navigate().GoToUrl("https://www.Facebook.com");
            driver.Manage().Window.Maximize();

        }
        [Test]
        public void TestScreenShot()
        {           

            Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
            ss.SaveAsFile("e:\\pande", System.Drawing.Imaging.ImageFormat.Jpeg);
        }

        [TearDown]
        public void TearDown()

public void TakeScreenshot(string saveLocation) {
        var location = GetPath() + _name + "\\" + saveLocation + ".png";
        var ssdriver = _driver as ITakesScreenshot;
        var screenshot = ssdriver.GetScreenshot();
        screenshot.SaveAsFile(location, ImageFormat.Png);
    }

此代码将帮助您拍摄屏幕截图

JAVA

protected void fullPageScreenshot(String testname) {
            String timeStamp = new SimpleDateFormat("dd_MM_yyyy_HH_mm_ss").format(Calendar.getInstance().getTime());
            String imageName = testname + "-" + timeStamp + ".png";
            Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(2000))
                    .takeScreenshot(DriverManager.getDriver());
            try {
                ImageIO.write(screenshot.getImage(), "PNG", new File("./FullPage_Screenshots/" + imageName));
            } catch (Exception e) {
                System.out.println("Capturing FullPage Screenshot failed");
            }
        }

使用 Ashot 库获取整页截图 - 即使页面需要滚动 https://mvnrepository.com/artifact/ru.yandex.qatools.ashot/ashot/1.5.4

使用 System.Drawing.Imaging 参考。以下代码可用于截屏。

IWebDriver driver = new FirefoxDriver();
ITakesScreenshot screenshotDriver = driver as ITakesScreenshot;
Screenshot screenshot = screenshotDriver.GetScreenshot();
String fp = "D:\\" + "snapshot" + "_"+ DateTime.Now.ToString("dd_MMMM_hh_mm_ss_tt") + ".png";
screenshot.SaveAsFile(fp, ImageFormat.Png);

注意：时间戳有两个好处：1）你会在截图时知道完美的日期时间。2) SaveAsFile 函数覆盖现有文件。因此，DateTime 可以帮助创建不同的文件。

        scj = new ScreenCaptureJob();
        // Specify the path & file name in which you want to save         
        scj.OutputScreenCaptureFileName = @"C:\Users\jpavankumar\Desktop\Screencaptuere\ScreenRecording4.wmv";

在全局代码中定义：

var counter = DateTime.Now.Ticks.ToString();

((ITakesScreenshot)driver).GetScreenshot().SaveAsFile((snap +counter + ".jpg").ToString(), OpenQA.Selenium.ScreenshotImageFormat.Jpeg);
test.Log(LogStatus.Fail, "Snapshot below: " + test.AddScreenCapture(snap + counter + ".jpg"));

在 python 中以通用方式截取屏幕截图并存储在文件位置的最佳方法：

def screenShots(self):
        fileName= NewFile + "." + str(round(time.time() * 1000)) + ".png"
        screenshotDirectory = "../screenshot/"  #Move to that directory where you want ot store the screenshot
        relativeFileName = screenshotDirectory + fileName
        currentDirectory = os.path.dirname(__file__)
        destinationFile = os.path.join(currentDirectory,relativeFileName)
        destinationDirectory = os.path.join(currentDirectory,screenshotDirectory)

        try:
            if not os.path.exists(destinationDirectory):
                os.makedirs(destinationDirectory)
            self.driver.save_screenshot(destinationFile)

            self.log.info("Screenshot saved to directory" + destinationFile)

        except:
            self.log.error("Exception Occured")
            print_stack()

使用 selenium 有两个我熟悉的调用：captureEntirePageScreenshot和captureScreenshot. 您可能想查看这些调用，看看它们是否会完成您所追求的目标。
