Nimble extensions that make unit testing with RxSwift easier

Why

RxSwift includes a really nifty little library called RxBlocking which provides convenience functions for peeking in on Observable instances. Also, there is a library called RxNimble which provides some operator overloads for equality checking. But sometimes we need more complicated matching than just equality, so this is why I created this library.

Currently you type something like this:

let observable = Observable.of(0, 1, 2, 3)
expect { try observable.toBlocking().last() }.to(equal(3))

Now you can only type:

let observable = Observable.of(0, 1, 2, 3)
expect(observable).toEmitLast(equal(3))
