Michael and Dan, thanks for the responses.
Let's say I had a custom component Login.mxml which is a simple login
box.
How would I set that up for testing in my testing
application with FlexUnit? Would this be the way you would
suggest?
I
guess that if I were to move my Login.mxml into 'net.acme.project.views' then I
could just instantiate them and test them :
net.acme.project.views.Login. Thus:
import
net.acme.project.view.Login;
Function
setup(){
myLoginView
= new Login();
}
Function
testLogin():Void
{
assertTrue('username getter isn't pre-set
correctly', myLoginView.getUsername(), 'Enter
Username...');
}
That
might be the path that I start down unless I'm missing something. I'm not
using View Helpers now just for clarity. Adding a testing suite to the
Cairngorm demo example would be a good investment IMHO.
Thanks,
Allen

I'm tackling a simlar thing at the moment too :)
I'm trying to
test AS business delegate methods to check that they correctly call remote java
methods. The delegates try and use something like "this.service =
ServiceLocator.getInstance().getService( "applicationDelegate" );".
But how do instantiate my ServiceLocator (in my case
Services.mxml)????
Also, how do I test the asynch remote calls?
In java I would do something like create a MockResponder as an inner class
and put a wait() in my test and have the onResult() and onFault() methods call
notify(). AS doesn't support inner classes (though I suspect Delegate is
the answer somehow). Thoughts???
cheers

Its an interesting problem Allen, and one that ive been trying
to tackle for a while.
The easiest way to do this is
to:
Var
view:Object;
Function
setup(){
View.myLabel = new
Label()
viewHelper = new myViewHelper()
viewHelper.view =
view;
}
You can do this with
most of the standard controls. Instantiating a mxml file directly from action
script seems to be a lot more difficult. I've had
some luck with
instantiating the mxml normally as a class, the calling init(). I'm sure
somebody will reply to this with the correct way to do
it!
The next
step is to take the mock view and extract it in to a separate
class:
Class
com.views.mockView{
Var
myLabel:Label;
mockVieW(){
this.myLabel =
new Label
}
}
...
..
Function
setup(){
viewHelper.View = new mockView();
}
The major disadvantage of this approach is that you will have to
be sure to
Keep your actual view and mock view "in-sync", but overall, you
should be
able to reliably unit tests your view
helpers.
Ta,
Mike

[flexcoders] Using FlexUnit with Cairngorm
Hello
Flexcoders,
I've started using FlexUnit to test business logic in
my business delegates.
I would now like to use
FlexUnit to test my View Helpers and getter / setter functions in the
views themselves. Does anyone have any examples of how one may run
tests against their mxml views?
For example, if I want to test
that a function getLabel():String placed in the root of mx:Application in file
'index.mxml' returns the string 'myLabel', how would I go about writing my
test?
public function testGetLabelFromView() :
Void
{
myViewToTest =
mx.core.application.Application;//?? how do I get access to this
??
assertEquals('should be ', 'myLabel'
,myViewToTest.getLabel());
}
I'm going to run this test from a testing
application, tests.mxml so mx.core.application.Application refers to my
testing application and not the target application I wish to
test.
Do I need to instantiate my target application in the tests
themselves? Like this:
public function
testGetLabelFromView() : Void
{
myViewToTest =
index;//do I call this as a class?
assertEquals('should
be ', 'myLabel' ,myViewToTest.getLabel());
}
Any help would be
greatly appreciated.
Many Thanks,
Allen
