/**
* FSTSpecTests run a set of portable event specifications from JSON spec files against a
* special isolated version of the Firestore client that allows precise control over when events
* are delivered. This allows us to test client behavior in a very reliable, deterministic way,
* including edge cases that would be difficult to reliably reproduce in a full integration test.
*
* Both events from user code (adding/removing listens, performing mutations) and events from the
* Datastore are simulated, while installing as much of the system in between as possible.
*
* FSTSpecTests is an abstract base class that must be subclassed to test against a specific local
* store implementation. To create a new variant of FSTSpecTests:
*
* + Subclass FSTSpecTests
* + override -persistence to create and return an appropriate id<FSTPersistence> implementation.
