Cool - glad to hear you're up and running.

 Hi! Thanks for the help -- and as of now, everything is running fine
 without asm-attrs.jar, though I'll keep it in mind just in case.. ;-)

Re: EasyMock for GWT + MVP ?

2009-10-25 Thread lowecg2004 

Your error looks like you're using the EasyMock class extensions and
are missing cglib jars from your build path.

As it happens, I recently produced a getting started with MVP and unit
testing with EasyMock article which might be of use:

Cheers,

Hi! Thanks for the heads up -- however, I find a couple of details:

* I added asm-3.1.jar and cglib-2.2.jar, which were in the GWT 2.0
tools/lib directory, but there was no asm-attrs.jar; do you still need
it?

* When running an empty JUnit (*not* GWTTestCase) test, which just
does loginViewMock=createMock(LoginView.class) I get another
exception... The GWT.create( ) problem -- how did you handle it? Or
did I miss a step in your article?

Re: EasyMock for GWT + MVP ?

2009-10-25 Thread Arthur Kalmenson 

It's possible to use EasyMock to mock out GWT widgets in a standard
JUnit or TestNG test, but you need to use GWTMockUtilities to disarm
GWT.

Re: EasyMock for GWT + MVP ?

2009-10-25 Thread lowecg2004 

As Arthur said, calling GWTMockUtilities.disarm() will prevent that
error (that was in part 2 of my article :)

As for needing asm-attrs.jar, I guess try it - any
NoClassDefFoundError that looks asm related then that will answer your
question...

Cheers,

You'd generally mock your LoginPresenter.Display interface (or however
you called it, your probably have one; otherwise, here is when it is
useful to have one ;-) ), not your LoginView, which uses widgets,
which need GWTMockUtilities (but it does not always work: History for
instance cannot be used in pure Java, even with
GWTMockUtilities.disarm()).
