mocking Functions

[grep]

Hi there I am using parsley in my project. Parsley provide a messaging
mechanism via a function Object. Here is a example:

package
{
public class SomeClass{

[MessageDispatcher]
public var sendMessage:Function;

public function sendSomeMsg():void
{

}

}
}

[grep]

if (a){
sendMessage(new AMessage());
}else{
sendMessage(new BMessage());
}
}

}
}


Is there a way to 'spy' on the Function object so i can test that the
correct message is sent?

Thank a million.

I would do:

1) Create a class with some function that accepts message.
public class MyMockieSender
{
    public function sendMessage(msg:*):*
    {
    }
}

2) Create mock for this class

var mockieSender:MyMockieSender = mock(MyMockieSender);

3) Take the sendMessage function pointer of the mockieSender and assign it to the SomeClass instance:

var someClass:SomeClass = new SomeClass();
someClass.sendMessage = mockieSender.sendMessage;

4) Make the test call

someClass.sendSomeMsg();

5) And verify on the mock what got called

verify().that(mockieSender.sendMessage(any()));

Hope this helps

Cheers,
Kris
