Assertions are the glue that connects `TestObserver`/`TestSubscriber` and Matcher.

Example

testObserver should complete()

testSubscriber shouldHave value("Hello!")

RxTest Assertions

should <Matcher>
shouldHave <Matcher>
shouldBe <Matcher>
shouldEmit <Matcher>

`shouldEmit` and `shouldNeverEmit` are special assertions that already contain matcher.

ShouldEmit is the assertion `shouldHave` with the matcher `value`.

shouldEmit <T>
shouldEmit <(T) -> Boolean>

shouldNeverEmit is the assertion `should` with the matcher `never`.

shouldNeverEmit <T>
shouldNeverEmit <(T) -> Boolean>
