Description

This PR adds test cases for:

EventHub's EventHistory related methods

func getHistoricalEvents(_: [EventHistoryRequest], enforceOrder: Bool, handler: @escaping ([EventHistoryResult]) -> Void)
func recordHistoricalEvent(_: Event, handler: ((Bool) -> Void)? = nil)

One big motivation for adding test coverage here was the update to change EventHub's implementation of getHistoricalEvents in PR:

• Implement event history insert and insertIfNotExists consequence support #1121

Where there were no test cases validating the behavior of the handler being called or not in the eventHistory is nil case.

Before

eventHistory?.getEvents(requests, enforceOrder: enforceOrder, handler: handler)

After

eventHistory?.getEvents(requests, enforceOrder: enforceOrder, handler: handler) ?? handler([])

Event's new support for conversion to EventHistoryRequest via .toEventHistoryRequest

Tests the conversion of Event into an EventHistoryRequest especially when different event masks are set.

Other changes

New MockEventHistory that provides a mock implementation for the EventHistoryService protocol.
