I'm trying to set up a fake context for use in unit tests, by inflating an in-memory database to run some of our queries. I'm running into a chicken and egg problem with our login process, though.

By default, the first login to the BOS is a LoginCredential. This allows the user to read back a list of users (in our UI, this let's us show a dropdown). All other access is locked down until a user logs in with credentials. My question is, how do I inject fake user data into the system *before* log in, so that I can authenticate against credentials in the DB?

Is this even possible (via a RestoreCacheState, for example)?

Thanks,

Rob
