webdriver - Selenium webdriver C# - 获取整页截图

Question

任何人都可以帮助我使用 Selenium webdriver 截取整页屏幕截图。我正在使用 c#/Nunit。我正在使用的当前方法不是完整的浏览器页面。

我正在使用下面的代码截取屏幕截图。

public void TakeScreenShot(IWebDriver webDriver,string testName,string className)
{          

string folderName = String.Format("{0}.{1}", className, testName);

// Create Screenshot folder
string createdFolderLocation = CreateFolder(folderName);

// Take the screenshot            
Screenshot ss = ((ITakesScreenshot)webDriver).GetScreenshot();            
string screenshot = ss.AsBase64EncodedString;
byte[] screenshotAsByteArray = ss.AsByteArray;

// Save the screenshot
ss.SaveAsFile((string.Format("{0}\\{1}",createdFolderLocation,testName + ".Jpeg")), System.Drawing.Imaging.ImageFormat.Jpeg);
ss.ToString();

}

Answer 1

我在我们的解决方案中使用了这个:

 public byte[] TakeScreenshot()
    {
      try
      {
        var getMaxSide = "return Math.max(document.body.scroll{0}, document.body.offset{0}, document.documentElement.client{0}, document.documentElement.scroll{0}, document.documentElement.offset{0})";
        var scrollHeight = (Driver as IJavaScriptExecutor).ExecuteScript(string.Format(getMaxSide, "Height"));
        var scrollWidth = (Driver as IJavaScriptExecutor).ExecuteScript(string.Format(getMaxSide, "Width"));
        Driver.Manage().Window.Size = new Size(int.Parse(scrollWidth.ToString()), int.Parse(scrollHeight.ToString()));
        return (Driver as ITakesScreenshot).GetScreenshot().AsByteArray;
      }
      catch
      {
        return Array.Empty<byte>();
      }
    }

然后您可以使用结果将其附加到例如Allure 或 NUnit 测试结果:

 private void AttachScreenshot()
    {
      var screenshot = _browser?.TakeScreenshot();
      if (screenshot.Length > 0)
      {
        // add screenshot to test results
        var path = DateTime.Now.Ticks.ToString() + ".png";
        File.WriteAllBytes(path, screenshot);
        TestContext.AddTestAttachment(path, "screenshot");

        // attach screenshot to Allure report
        AllureLifecycle.Instance.AddAttachment("screenshot", "image/png", screenshot);
      }
    }
