RxTest vs. XCTestExpectation

CocoaHeads Florianópolis

In order to compare RxTest to XCTestExpectation, an extremely simple game was built using RxSwift and each commit tells a story of its evolution.

The game has the following requirements:

1. Every tap should increment 1 in the score
2. The first tap also starts the timer, which should countdown until its end
3. The score can only be incremented while the timer is running
