// routine. This allows the test to be fully synchronous and deterministic while still being able
// to validate the logic of most of the watching and state updating.
//
// The general strategy here is to:
//
// 1. Initialize a state with a call to newState + setting some of the extra stuff like the CacheNotifier
// We will not be using the CacheNotifier to send notifications but calling handleUpdate ourselves
// 2. Iterate through a list of verification stages performing validation and updates for each.
// a. Ensure that the required watches are in place and validate they are correct
// b. Process a bunch of UpdateEvents by calling handleUpdate
// c. Validate that the ConfigSnapshot has been updated appropriately
