[Jonas Sicking (:sicking) No longer reading bugmail consistently]

The tests here look a bit lacking. Is it really testing that opening an existing database opens it with the database's existing version and objectStores, and that if there exists no database, a new one is created with version 1?

It's not testing anything with objectStores, but it is testing the version bits.

Adding more tests isn't hard.

Nit: This isn't argc, it's the number of optional args passed. Call it 'aOptionalArgCount'
