modified method stubs to make test pass

I'm still pretty new to making pull requests and the like, so apologies if I do something wrong.

I'd like to make some contributions to vrapper, but I noticed that this test wasn't passing. I mocked the configurations to return the right values as I saw done in NormalModeTests, which caused the test to pass.

Hopefully I'm not just looking at the wrong source and this was fixed already.
