Issue Description

The Issue/Exception occurs when tests are running in parallel mode. Setup Used: Selenium Grid Architecture [HUB & NODE]

Steps to Reproduce

Using Appium/WinAppDriver to automate the Windows Application. The issue occurs when Selenium Grid is used to run the Tests in Parallel Mode.

When the tests are run in Single-mode the exception does not occur.

Note:- When two nodes are setup and are connected to HUB and 2 Scenarios are run, the exception is thrown, however, the issue does not appear when one node is connected to HUB.

Tech Stack: C#, SpecFlow, WinAppDriver, Nunit [Test Runner]

Scenario:

This is an Automation Test project where I need to integrate parallel testing using Selenium grid architecture. I have setup HUB and NODE and when I try to run multiple test cases [Say 2] I get the below exception.

Added Below Attributes in AssemblyInfo.cs file to run the tests in Parallel mode

 public InitializeWinAppDriver(){
   this.webDriver = new WindowsDriver<WindowsElement>("{uri of Hub}","{appium options}");
   objectContainer.RegisterInstanceAs<WindowsDriver<WindowsElement>>(webDriver);
