Re: [Asunit-users] Testing view classes (subclasses of MovieClip and the likes)

Hi Luke, thanks for the reply :)

It is still not clear to me the role of MovieClip classes on asunit unit
tests. From what I've been reading about Unit Testing so far, I can
understand that visual entities should not be unit tested directly. Instead,
the business classes that are used by it should be tested and I don't think
business classes should inherit MovieClip (am I misunderstanding something
here?).

But let's say I really want to instantiate a MovieClip class on my unit
test. The XUL UI feature you described is for creating mock objects for
MovieClip classes, right? I'm asking this becouse it would be too much of a
stress to try to instantiate a regular "non-serializable" MovieClip class as
it depends on assets that are not present on the test swf library (and
should not be present, I'm almost sure!).

Cheers,

Marcelo.
