How to get window using TestStack.White

Question

I have already get the top level Window by calling:

Window win = Desktop.Instance.Windows().Find(...);

But exception occurs when getting sub window:

IUIItem item = win.Get(SearchCriteria.ByText("The Name"));

An unhandled exception of type 'TestStack.White.AutomationException' occurred in TestStack.White.dll

Additional information: Failed to get Name=The Name

I haven't found too much info from TestStack.White https://github.com/TestStack/White. I suspect it is because the sub window isn't an Automation control.

Answer 1

First of all it is not a good idea to look for all desktop windows. You should launch your application providing application path:

TestStack.White.Application app = TestStack.White.Application.Launch(applicatonFullPath);

Then you should get main window for your application:

mainWinDow = app.GetWindows().FirstOrDefault(w => w.Name == "YOUR MAIN WINDOW NAME");

Your sub window is probably a modal window. You can get it like his:

var modalWindows = mainWinDow.ModalWindows();

modalWindow = modalWindows.Where(x => x.Name == "The Name").FirstOrDefault();
