Unit test classes with lwuit usage

Question

I'm working under quite old app which uses LWUIT for UI.

I'm trying currently to write unit tests for MIDlet class but because there are a lot of LWUIT static methods calls it's quite hard to make it properly working even with PowerMock.

Does anyone have example of what should be completely mocked, suppressed to finally have these tests run?

There is way too much to mock. You can either build your own LWUITImplementation class which will allow you to do some of these things (see the ports for the various platforms). Or you can migrate the code to Codename One which has its own unit testing framework and test recorder.

How could I inject own Implementation to LWUIT? – Eugen Martynov Feb 28 '13 at 10:05
You need to implement the ImplementationFactory class to return the right class instance. – Shai Almog Mar 03 '13 at 08:06
Interesting how is this "wiring" is going. I will check tomorrow. Should I call some setter to inject my implementation? – Eugen Martynov Mar 03 '13 at 16:47
You need to replace the ImplementationFactory class with your own. – Shai Almog Mar 04 '13 at 14:22
I mocked LWUITImplementation with ImplementationFactory and I'm writing tests for classes that are using LWUIT. Thank you! – Eugen Martynov Mar 04 '13 at 14:25

I've actually extracted all LWUIT initialization and theme related code to a special class. I could mock it and at least test all other app functionality.

The code that is relied on LWUIT like forms and controls requires a lot of PowerMock tricks
