// These tests check the default out-of-the-box behavior of Ghost is working as expected.

// Test Structure
// As it stands, these tests depend on the database, and as such are integration tests.
// Mocking out the models to not touch the DB would turn these into unit tests, and should probably be done in future,
// But then again testing real code, rather than mock code, might be more useful...
