Created Issue: Quiet test failures on Vista

viveksingh — Sun, 05 Jul 2009 10:09:24 GMT

I've run into a quirky issue with application window focus when running tests with the following setup:

Vista SP1
.NET 3.5 SP1
WinForms App
Running tests from nunit-console

When I run tests from a console window and the console window has focus/is topmost everything works fine. When another window besides the console window has focus at the time the tested application starts, attempts to find components on the tested application window fail quietly.

For example, the code below will proceed quietly with no errors until throwing a null-reference exception on the last line:

Application myApp = Application.Launch("MyApp.exe");
Window mainWindow = myApp.GetWindow(SearchCriteria.ByAutomationId("MainForm"), InitializeOption.NoCache);
mainWindow.MenuBar.MenuItem("File").Click();
Window modal = mainWindow.ModalWindow("myModalWindow");
modalWindow.Get<Label>("some label);

The app starts but the window is not top-most.
The Application.GetWindow() call returns a window reference.
MenuBar.MenuItem.Click() hangs unitl the BusyTimeout expires and then proceeds with no timeout exception.
mainWindow.ModalWindow() hangs and then proceeds with no error, but does not actually return the modal window (which doesn't exist because the menu item was never clicked).

The only way I've found to eliminate this is to call Window.Focus() after getting the main window.

Just to be clear:

There is no user mouse or keyboard activity going on during the test.
The exact same code works fine 100% of the time when the console window has initial focus and fails 100% of the time when it does not have focus.

I'm fine with the Focus() workaround, but this did cost me a fair bit of time and is frustrating because of its intermittent nature. I thought it was worth pointing out to help other folks and in case a fix can be implemented in White itself.

Regards,

Ashley

It's not #3 on that discussion. The test works 100% of the time when the console window has initial focus and fails 100% when another window has initial focus. Also, the issue affects calls to get other components besides MenuItems and doesn't report any find-failure--just returns from the get call with no errors.

Turned out I was doing something dumb with user controls and AccessibilityObjects. Don't worry about it...

The Core assembly has now been renamed to White.Core, could you also please consider renaming the namespaces to White.Core.? Not as such causing me any problems, but it may be confusing for new users.

viveksingh — Sat, 04 Jul 2009 09:37:41 GMT

my thought process went like this.

since this tool is going to allow automation of WPF, SWT, Win32, Silverlight and WinForm apps, I started thinking on lines of what you get when you put everything together.

I thought about colors and hence white (i.e. when you put all primary colors).

Not very well thought out, but for what it is worth.

before I investigate this issue. can you let me know what generic type you are supplying with window.Get call?

is there a reason you are not using Spinner class which comes with white?

Hi I am also a new white user, need to know which project should i start with like, console application or windows application.

if we choose windows application then it creates problem for application class, which is present core.Application as well as in System.Windows.Forms

please suggest how should we resolve this...

Thanks...

private Core.Application whiteApplication;
private System.Windows.Forms.Application windowsApplication;

instead of Application so you can use both.

Got this exception on calling Window.Get("nxsProductShortName")

Any idea why White would be throwing an exception?

New Post: Copy or reference?

Natook — Thu, 02 Jul 2009 12:29:20 GMT

A real newbie question

I'm playing around with accessing a datagridview, changing cell values and so on. When I deleted a row I realized that I needed to get the datagrid again in order to notice the change (row count stayed the same otherwise). I'm assuming that get<UIItem> provides me with a copy of the object, is that correct?

New Post: COMException being thrown randomly

nigelthorne — Thu, 02 Jul 2009 06:11:40 GMT

My simplest example of this is

[Test]
public void COMExceptionTest()
{
   var window = AutomationElement.RootElement.FindFirst(TreeScope.Children,
                                                                  new PropertyCondition(AutomationElement.NameProperty, "Window1"));

   for (int i = 0; i < 1000; i++)
   {
      var count = window.FindAll(TreeScope.Descendants, new PropertyCondition(AutomationElement.AutomationIdProperty, "complexControls")).Count;
      Assert.AreEqual(1, count);
   }
}

where there is a WPF app running with a title Window1 and a listview on it called complexControls.

Natook — Wed, 01 Jul 2009 13:49:55 GMT

I'm just starting out today, but unfortunately I have to agree. Although I like the name, it has a sense of simplicity and purity about it, searching for help is hard.

As for suggestions, what were the original thoughts when the name was selected?
