JUnit Test Initialization

Hi Everyone,

I'm writing my first JUnit test for a WebObjects Application and I've hit a roadblock.  I need access to some of the data in the database.  When I just try to run the test I get an error: "java.lang.IllegalArgumentException: An object store for the entity "Account" could not be found. Verify that the entity is defined in an EOModel, and that the model is installed properly. To see what models are loaded, you can try printing the return value of EOModelGroup.defaultGroup() in your application."

Seems I need to initialize my application, so I tried this advice on the wiki: http://wiki.objectstyle.org/confluence/display/WO/Testing-JUnit+and+TestNG to initialize the app, but then I get a NPE:

java.lang.NullPointerException

    at com.example.tests.YourOrdersTest.initWO(YourOrdersTest.java:51)
    <snip>

and the console message: "It seems that your application class com.example.Application did not call er.extensions.appserver.ERXApplication.main(argv[], applicationClass) method. Please modify your Application.java as the followings so that er.extensions.foundation.ERXConfigurationManager can provide its rapid turnaround feature completely. "

Any help setting up this test would be greatly appreciated.

Thanks,

Joe
