I am currently in the process of automating the UWP application using WinAppDriver/Appium and Selenium WebDriver.
I am facing an issue while getting the value attribute for the text box. I tried getting Legacy Value as well as Value.Value but getting null

WinAppDriverLog:

TestCode:

    WebElement text =WinDriver.driver.findElementByName(locator);
    Log.info("Verifying " + expected + " text....");
    Assert.assertEquals(text.getAttribute("LegacyValue"), expected); //Legacy|Accessible.Value
    Log.info("EXPECTED VALUE: " + expected + " ACTUAL VALUE: " + text.getAttribute("Value.Value"));


}

WinDriver Code

public class WinDriver {

    public static WindowsDriver<RemoteWebElement> driver = null;

    public static void start(String appPath)
    {
        Log.info("Setup");
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("automationName", "Windows");
        capabilities.setCapability("app",appPath);
        capabilities.setCapability("platformName", "Windows");
        capabilities.setCapability("deviceName", "WindowsMachine");
        try {
            driver = new WindowsDriver<>(new URL("https://127.0.0.1:4723"), capabilities);
        } catch (MalformedURLException e) {
            throw new RuntimeException(e);
        }
    }

I am confused as I tried getting “LegacyName” ( as per suggested here>> https://github.com/microsoft/WinAppDriver/blob/a6f3d7bca447e0c13a33f76454600c1fe737ab10/Tests/WebDriverAPI/ElementAttribute.cs#L46%5C%5C>and it worked but unfortunately “LegacyValue” or “Value.Value” does not work.

Thank you all in advance!!!

I tried to fetch the value using WebElement.getAttribute(“Value.Value”) and WebElement.getAttribute(“LegacyValue”). I was expecting to get value using getAttribute
