Question

I'm trying to take a screenshot on test failure.

    [TearDown]
    public void TearDown()
    {
        var status = TestContext.CurrentContext.Result.Outcome.Status;
        var stackTrace = "<pre>" + TestContext.CurrentContext.Result.Message + "</pre>";
        var errorMessage = TestContext.CurrentContext.Result.Message;
        if (status == NUnit.Framework.Interfaces.TestStatus.Failed)
        {
            test.Log(LogStatus.Fail, status + errorMessage);
            var ScreenShotPath = GetScreenShot.Capture(_webdriverChrome);
            test.Log(LogStatus.Fail, "Screen Shot Below: "+test.AddScreenCapture(ScreenShotPath));
        }
        else if (status == NUnit.Framework.Interfaces.TestStatus.Passed)
        {
            test.Log(LogStatus.Pass, status + errorMessage);
        }
        extent.EndTest(test);
        _webdriverChrome.Quit();}

and the capture function is

 public static string Capture(IWebDriver Webdrievr)
    {
        string pth = System.Reflection.Assembly.GetCallingAssembly().CodeBase;
        string actualPath = pth.Substring(0, pth.LastIndexOf("bin"));
        string projectPath = new Uri(actualPath).LocalPath;

        Screenshot ss = ((ITakesScreenshot)Webdrievr).GetScreenshot();
        string screenshot = ss.AsBase64EncodedString;
        byte[] screenshotAsByteArray = ss.AsByteArray;
        ss.SaveAsFile(projectPath + "ErrorReportScreenshot\\ErrorScreenshot.jpeg", ScreenshotImageFormat.Jpeg); //use any of the built in image formating
        string _fullPathToReturn = projectPath + "ErrorReportScreenshot";
        return _fullPathToReturn;
    }

I'm getting an error

Result Message:
OpenQA.Selenium.WebDriverException : The HTTP request to the remote WebDriver server for URL http://localhost:56184/session/1aaf976356898c52e5cd57d17d44df15/element timed out after 60 seconds. ----> System.Net.WebException : The operation has timed out TearDown : OpenQA.Selenium.WebDriverException : The HTTP request to the remote WebDriver server for URL http://localhost:56184/session/1aaf976356898c52e5cd57d17d44df15/screenshot timed out after 60 seconds. ----> System.Net.WebException : The operation has timed out

The thing is that it fails taking the screenshots as long as I'm calling the capture() method from TearDown() . If I'm just calling the capture() by running it within a new test, it works like a charm. In debugging mode, I can see it fails on this row: Screenshot ss = ((ITakesScreenshot)Webdrievr).GetScreenshot(); what am I missing?

EDIT: I have watched the ((ITakesScreenshot)Webdrievr) and getting an error:

error CS0103: The name 'Webdrievr' does not exist in the current context

Answer 1

I found the problem . for some reason the following caused all of this

var options = new ChromeOptions();
options.AddArgument("no-sandbox");
_webdriverChrome = new ChromeDriver(options);

I just used the chromedriver without options and it works now.

_webdriverChrome = new ChromeDriver();

I am having similar issue while trying to take screenshot upon test failure. I get timed out error when I try to take the screenshot on failure condition. It works fine in try block but timed out in catch block. I am not using Chrome options as the solution provided above. Any help would be appreciated.

Below is the method to take screenshot:

public class Logging
    {
      public static void ErrorScreenshot()
        {
        //Take the screenshot
        Screenshot ssh = ((ITakesScreenshot)Driver.BrowserInstance).GetScreenshot();
        //Save the screenshot
        ssh.SaveAsFile("C:/Users/", ScreenshotImageFormat.Png);
        } 
     }

This is my test method

public static bool FindElement
    {
      get
      {
          try
          {
             var element = Driver.BrowserInstance.FindElement(By.XPath("  "));
             if (element != null)
             {
               return true;
             }
          }
          catch (Exception ex)
          {
             Logging.ErrorScreenshot();
             Logging.Error("Not able to find element" + ex.ToString());
          }
          return false;
     }

  }

when it is not able to find the element it goes to catch block and there Logging.ErrorScreenshot method throws a timed out exception.
