FindElementByAccessibilityId throws WebDriverException

Hi Team,

I am using WinAppDriver to automate my windows application. On using FindElementByAccessibilityId to find the element on the application, I am getting the exception “OpenQA.Selenium.WebDriverException: 'An element could not be located on the page using the given search parameters.'”

I am using Inspect tool to inspect the element on the application and getting the value of the property ‘AutomationId’ and providing as string for FindElementByAccessibilityId method.

Could someone help me to understand why I am getting the exception?

Thanks in advance

My Sample Code:

public void TestMethod1()
        {
            //WinAppDriver and Application started before the test execution
            String _appName = "GUIApplication";
            AppiumOptions dc= new AppiumOptions();
            AppiumOptions mc= new AppiumOptions();
            dc.AddAdditionalCapability("platformName", "Windows");
            dc.AddAdditionalCapability("app", "Root");
            WindowsDriver<WindowsElement> session1= new WindowsDriver<WindowsElement>(new Uri("http://127.0.0.1:4723"), dc);
            session1.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(100);
            AppiumWebElement element = session1.FindElementByName(_appName);
            string AppHandle= element.GetAttribute("NativeWindowHandle");
            int HandleInt= int.Parse(AppHandle);
            string HandleHex = HandleInt.ToString("x");
            mc.AddAdditionalCapability("appTopLevelWindow", HandleHex);
             WindowsDriver<WindowsElement> current = new WindowsDriver<WindowsElement>(new Uri("http://127.0.0.1:4723"), mc);
            current.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(100);
            bool result = current.FindElementByAccessibilityId("ABCDEF").Displayed; //Throws Exception
        }

@iamkrk Real extracted by WinAppDriver page source can be different from Inspector Could you save the page source and check that control really presents in XML with the expected attributes (use driver.PageSource) and then check that XPath working using http://xpather.com/? Xpath will be something like: //*[@AutomationId=‘FirsatNameTextbox_First Name *’]

Nope. Still throws the exception.

If I just use as below it works.

bool result = current.FindElementByName("First Name *").Displayed;

Am curious to understand why on using FindElementByAccessibilityId throws exception.

Thanks
