Coded UI - Cross browser issue. Not able to identify controls on Chrome - google-chrome

Question

I have a web application hosted on http://localhost/MyWebApplication. And I am using Coded UI as a tool to perform UI Automation on the application
I have to carry out concurrency kind of scenaios where in two different admin users (say user1 & user2) login to http://localhost/MyWebApplication. When user1 performs any operation like edit or delete the same should be reflected on data for user2
To achieve this, I am logging into MyWebAppliction on IE browser as user1 & Chrome browser as user2. And I am able to launch and login to IE & Chrome as user1 & user2 respectively.
Now after I perform some edit, delete operation on user1 in IE, I need to go back & check if it is reflected in user2 in chrome. And I need to do Vise-versa as well (i.e Chrome to IE)
To switch between the browsers, I have writtent below method to bring the required browser (IE or chrome) to foreground
using System.Runtime.InteropServices;
using System.Diagnostics;
[DllImport("user32.dll")]
public static extern bool SetForegroundWindow(IntPtr hWnd);
public void SwitchBrowserForMyWebApp(string browserName)
{
System.Diagnostics.Process[] p = System.Diagnostics.Process.GetProcessesByName(browserName).Where(x => x.MainWindowTitle.Contains("My Web Application")).ToArray();
if (p.Length > 0)
{
SetForegroundWindow(p[0].MainWindowHandle); // bring the desired browser to the front
}
// ========== Till here it works fine & brings the required browser to the front.
BrowserWindow curWindow;
if (browserName == "iexplore")
{
BrowserWindow.CurrentBrowser = "IE";
}
else
{
BrowserWindow.CurrentBrowser = browserName;
Process browserProcess = p[0];
BrowserWindow bwp = BrowserWindow.FromProcess(p[0]); // Here it gives null exception - Object not set to instance of an object
//BrowserWindow.Locate("My Web Application - Google Chrome");
}
}
Problem I am facing here is, If i bring IE to foreground, then I am able to access controls and perform edit or update
But if I bring chrome to foreground, then I am unable to access any of the controls on chrome.
I tried setting CurrentBrowser as "Chrome", used BrowserWindow.Locate("My Web Application - Google Chrome"), Also used BrowserWindow.FromProcess(p[0]);
Not able to find what is the issue. I am using IE 11 & Chrome version: 47.0.2526.111 m
Can any one let me know if I am missing anything. Or any work around to resolve this issue
Thanks in Advance

Answer 1

I haven't tried this, but Setting the "CurrentBrowser" Property does not switch browsers. This property has to be set before you call the Browser.Launch() Method to initialize the browser driver u use. It's defaulted to IE. U will have to use two different Browser Instance and use the one need. May be something like this,
public static BrowserWindow CurrentBrowser= null, Chrome = null, IE = null;
IE = BrowserWindow.Launch(new Uri("http:\\urAppURLHere.COM"));
BrowserWindow.CurrentBrowser = "Chrome"
Chrome = BrowserWindow.Launch(new Uri("http:\\urAppURLHere.COM"));
CurrentBrowser = GetMeTheBrowserIWant("Chrome");
public static BrowserWindow GetMeTheBrowserIWant(string BrowserType)
{
if(BrowserType.ToUpper().Equals("CHROME")
{
return Chrome;
}
if(BrowserType.ToUpper().Equals("IE")
{
return IE;
}
}

Answer 2

You are Switching the Browser, but the Test Object u identified is still instantiated with Chrome.
You will have to re identify the Test Object using IE Again.
Something like,
GmailLogOnButton = new HtmlControl(GetMeTheBrowserIWant("IE"));
GmailLogOnButton.SearchProperties.Add(HtmlControl.PropertyNames.Id, "signIn");
Coded Ui framework is not developed considering Concurrent execution of Same Steps. So when you try concurrency tests, u will end up doing additional steps.
You, may also consider using Threading, but it may create difficulties in how u sync your tests!!
