Hello There,

I have been enjoying playing with white for quite few days now. Its cool.. Thank you so much Vivek and Team. 

I have been able to create Screen Classes and test them from a Console program (initializing them and calling their methods etc), however I am running into a crazy problem. The window.MenuBar function fails when the call is made through NUnit (I tried both GUI and console of NUnit). But the same program runs fine when used as a stand alone program. Here is my class, followed by the exception i get.

public Class MyScreen


private readonly Window window;

        private readonly Application application;

        public MyScreen(Application application, params string[] menuPath )


            this.window = application.GetWindow(SearchCriteria.All, InitializeOption.NoCache);

            this.application = application;

            SearchCriteria cr = SearchCriteria.All;

            IUIItem[] items = window.GetMultiple(cr);

            MenuBar menuBar = window.MenuBar;

            Menu level2Menu = menuBar.MenuItem(menuPath);            





 Bricks.BricksException : Error invoking MenuBar.MenuItem

----> Core.Factory.UIItemSearchException : Could not find Menu Name=Persons

 at Bricks.RuntimeFramework.ReflectedObject.Invoke(MethodInfo methodInfo, Object[] arguments)

I ran into this same issue on Windows XP. For various reasons it was inconvenient to use the /nothread option with Nunit (as described here:

Another workaround is to include the following in your test assembly configuration file:

<?xml version="1.0" encoding="utf-8" ?>
        <sectionGroup name="NUnit">
            <section name="TestRunner"
            <!-- Necessary for UI automation performed by White (Windows XP only) -->
            <add key="ApartmentState"
                 value="STA" />
