Expected behavior

Firebase Realtime Database is configured and I'm able to use injection token in Firebase Service to query the database.

I have no issues configuring Firestore in this same way. I'm able to do this same provider/injection token pattern using initializeApp and getFirestore and it works beautifully. What is the difference with getDatabase?

Actual behavior

Error: AngularFireModule has not been provided at getSchedulers is thrown and the web page is blank.

I'm also having this issue. I'm using authState method to capture the user as an observable in my service, and I can't get the tests to get passed this error.

Are there examples somewhere of tests that have been written for components that depend on these methods from the version 7 of the library?

Any news on this? I'm stuck with the same problem but with authState like @jakehockey10
