How to perform tests using Robolectric
I've trying to test my webservice layer which needs to instantiate some RushObjects without saving, and I'm getting this thrown:

There is no rush method being called in the test, just an instantiation of an rushobjects and insertion of some values
I haven't done any testing against Robolectric so will have to look into this before I can comment. Even though your not saving any objects you will be still calling initialize which will attempt to create the database schema.
Definitely a valid feature request for it to work with Robolectric, but for now you will just have to make sure initialize is not called when testing.
For work around, I created a class called RushAndroid on the package co.uk.rushorm.android in the test folder, that have the initialize method with stubbed implementation.
