Hi,
I’m having a problem with a unit test that uses the flexunit 4
UIImpersonator class and the buttonbar class when running it with
flex-mojos.
I’m posting it here because when I run the same test with the default
runner from eclipse the test passes every time.
Only when executing it with maven and the flexmojos I get this problem.
The unit test is pretty straightforward:
[Before(async,ui)]
public function setUp():void {
mainView = new MainView();
Async.proceedOnEvent(this, mainView,
FlexEvent.CREATION_COMPLETE, 2000);
UIImpersonator.addChild(mainView);
appModel = new AppModel();
mainView.appModel = appModel;
}
[Test(async,timeout="2000")]
public function testCloseProject():void {
Async.handleEvent(this, mainView,
UserEvent.HOME_USER_EVENT, closeProjectHandler);
var lastButtonIndex:int =
(mainView.topMenu.dataProvider as ArrayCollection).length - 1;
var closeButton:Button =
mainView.topMenu.getChildAt(lastButtonIndex) as Button;
closeButton.dispatchEvent(new MouseEvent(MouseEvent.CLICK));
}
public function closeProjectHandler(event:UserEvent,
param2:*):void {
mainView.topMenu.validateNow();
Assert.assertEquals(0, mainView.topMenu.selectedIndex);
}
The mainview has a topmenu property that’s a buttonbar.
<!-- top menu -->
<mx:ToggleButtonBar id="topMenu" styleName="topMenu"
dataProvider="{appModel.topMenuItems}"
itemClick="buttonBarClick(event)"/>
And the model that fills it is declared as follows:
public var topMenuItems:Array = ["General", "Close Project"];
Running the test through the flexunit 4 runner
(org.flexunit.flexui.TestRunnerBase) makes the test pass every time.
But running it with maven and the flexmojos I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null
object reference

I have a feeling that the problem lies within the UIImpersonator class
that sets the object on the stage, but I was wondering if someone had
a clue where to start looking because I’ve been trying for a day now
and I can’t find any leads.
I’ll paste my pom.xml for reference but I don’t suspect that’s the problem.
