toEqualNullIfNullGivenElse

Expects that the subject of this expectation is either null in case assertionCreatorOrNull is null or is not null and holds all assertions assertionCreatorOrNull creates.

expect<Int?>(null).toEqualNullIfNullGivenElse(null)

expect<Int?>(1).toEqualNullIfNullGivenElse { // subject inside this block is of type Int
    toBeLessThan(2)
}  // subject here is back to type Int?

fails { // because sub-expectation fails
    expect<Int?>(1).toEqualNullIfNullGivenElse {
        toBeLessThan(0)
    }
}

Return
