Unable to create new remote session

[yanan58]

I'm trying to start our WPF application.

Here are what I have done:

1. Followed the instruction "Running on a Remote Machine" in
   https://github.com/Microsoft/WinAppDriver/wiki/Frequently-Asked-Questions/289a8b325d3ddab9f08b4398c49163a9a136f607#what-to-do-when-an-application-has-a-splash-screen-or-winappdriver-fails-to-recognize-the-correct-window
   Note: I started WinAppDriver without "/wd/hub" since I want to use WinAppDriver standalone

2. Java code for starting up a WPF app:
   DesiredCapabilities capabilities = new DesiredCapabilities();
   capabilities.setCapability("deviceName", "WindowsPC");
   capabilities.setCapability("app", "C:\Users\xyz\Desktop\sv14web00041.appref-ms");
   appSession = new WindowsDriver(new URL("http://127.0.0.1:4723"), capabilities);
   Assert.assertNotNull(appSession);
   String winHandle = appSession.getWindowHandle();
   Thread.sleep(50000);

   Note: I tried both 127.0.0.1 and local IP

Log:
org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{app=C:\Users\xyz\Desktop\sv14web00041.appref-ms, platformName=Windows, deviceName=WindowsPC}], required capabilities = Capabilities [{}]

Any assistant would be truly appreciated.

Hi @yanan58,

What kind of app are you trying to automate? It seems that the remote connection with WinAppDriver is successful, but it is unable to locate the desired application.

Is there a .exe that you can target instead of the .apppref-ms (as this is just a reference and not the executable)?

[yanan58]

It's a WPF app. I open it by double clicking on an 'Application Reference' icon on desktop.
There is a splash screen before the app login window.
When ran the test scripts, I saw the splash screen opened/closed then two login windows were opened before SessionNotCreatedException

[yanan58]

From 'Task Manager' I found a .exe. But when I changed appId to the .exe, a app login window opened, but it was not the right app I want to open.

[hassanuz]

Is there an appx-recipe for the WPF app? If so, instead of using the URL in the packageID, you should be using the generated RegisteredUserModeID

From ReadMe:

You can find the Application Id of your application in the generated AppX\vs.appxrecipe file under RegisteredUserModeAppID node. E.g. c24c8163-548e-4b84-a466-530178fc0580_scyf5npe3hv32!App

[yanan58]

I got a standalone app, now I can get a new connection.
But I'm blocked by new issues.

My test script in java:
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName", "WindowsPC");
capabilities.setCapability("app", appId);
appSession = new WindowsDriver<WindowsElement>(new URL(winAppDriverUrl), capabilities);
Assert.assertNotNull(appSession);
appSession.manage().timeouts().implicitlyWait(2, TimeUnit.SECONDS);
appSession.findElementByAccessibilityId("EagleLoginUserName").click();
appSession.findElementByAccessibilityId("EagleLoginUserName").setValue("abc");

Got error:
Connected to the target VM, address: '127.0.0.1:62993', transport: 'socket' org.openqa.selenium.NoSuchElementException: An element could not be located on the page using the given search parameters.

I modified test script as below :
DesiredCapabilities appCapabilities = new DesiredCapabilities();
appCapabilities.setCapability("deviceName", "WindowsPC");
appCapabilities.setCapability("app", appId);
eagleAppSession = new WindowsDriver<WindowsElement>(new URL(winAppDriverUrl), appCapabilities);
Thread.sleep(2000);
DesiredCapabilities deskTopCapabilities = new DesiredCapabilities();
deskTopCapabilities.setCapability("platformName", "Windows");
deskTopCapabilities.setCapability("deviceName", "WindowsPC");
deskTopCapabilities.setCapability("app", "Root");
deskTopSession = new WindowsDriver<WindowsElement>(new URL(winAppDriverUrl), deskTopCapabilities);
Assert.assertNotNull(deskTopSession);
List<WindowsElement> eagleWindow = deskTopSession.findElementsByClassName("EagleChildWindow");
String winHandle = eagleWindow.get(0).getAttribute("NativeWindowHandle");

Got error:
java.lang.ClassCastException: org.openqa.selenium.remote.RemoteWebElement cannot be cast to io.appium.java_client.windows.WindowsElement

Start winapp driver like this WinAppDriver.exe ipaddress of your machine 4723/wd/hub

below is the code which is working fine

private static WindowsDriver<RemoteWebElement> driver = null;
public static void driverInstance() throws Exception 
{
	DesiredCapabilities capabilities = new DesiredCapabilities();
	capabilities.setCapability("app", "Root");
	capabilities.setCapability("deviceName", "WindowsPC");
	capabilities.setCapability("platformName", "Windows");
	driver = new WindowsDriver<RemoteWebElement>(new URL("http://"+"**ipAddress of the machine**:4723/wd/hub"), capabilities);
	driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}

[yanan58]

I made the changes as you mentioned:

DesiredCapabilities appCapabilities = new DesiredCapabilities();
            appCapabilities.setCapability("deviceName", "WindowsPC");
            appCapabilities.setCapability("app", appId);
            eagleAppSession = new WindowsDriver<RemoteWebElement>(new URL(winAppDriverUrl), appCapabilities);
            Thread.sleep(2000);
            Assert.assertNotNull(eagleAppSession);
            //Desktop root attach
            DesiredCapabilities deskTopCapabilities = new DesiredCapabilities();
            deskTopCapabilities.setCapability("platformName", "Windows");
            deskTopCapabilities.setCapability("deviceName", "WindowsPC");
            deskTopCapabilities.setCapability("app", "Root");
            deskTopSession = new WindowsDriver<RemoteWebElement>(new URL("http://127.0.0.1:4723/wd/hub"), deskTopCapabilities);

Got error: when executed the last line: new WindowsDriver<RemoteWebElement>(new URL("http://127.0.0.1:4723/wd/hub"), deskTopCapabilities);

org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{app=Root, platformName=Windows, deviceName=WindowsPC}], required capabilities = Capabilities [{}]

[prasanna532]

are you executing in remote machine or in local machine...

[yanan58]

Local.
I changed "new WindowsDriver<WindowsElement>()" to "new WindowsDriver<RemoteWebElement>()" based on your example

[prasanna532]

Start winapp driver like this WinAppDriver.exe ipaddress of your machine 4723/wd/hub Have done this Step

[prasanna532]

Local.
I changed "new WindowsDriver<WindowsElement>()" to "new WindowsDriver<RemoteWebElement>()" based on your example

Yes if you you do that you wont get Casting exception as i also faced same issue after doing that way it got resolved...

[yanan58]

I changed to my machine ipaddress and still got error
org.openqa.selenium.WebDriverException: org.apache.http.conn.HttpHostConnectException: Connect to 10.80.41.91:4723 [/10.80.xx.xx] failed: Connection refused: connect Build info: version: '3.3.1', revision: '5234b325d5', time: '2017-03-10 09:10:29 +0000'

[prasanna532]

If your are running in local you can go with the 127.0.0.1 or You can keep ipaddress also no issues. You need to keep the ipaddress only in case your running in Remote machines. like grid way.

Have you done this step C:\Program Files (x86)\Windows Application Driver\WinAppDriver.exe ipadddress 4723/wd/hub

[yanan58]

WinAppDriver.exe ipadddress 4723/wd/hub fixed the problem

[prasanna532]

Cool....... : )
