Invariant should be enough to run a test

[TheLudd]

I encountered a situation today where I want to group expectations for a range of inputs to a function. Some inputs should give a return value a, other inputs should give return value b. I thought I could group these assertions with an Invariant but since I lack a Then the tests are never executed.

Pseudo suite:

    describe 'I want the same result for different inputs', ->
        When -> @subject @input
        Invariant -> expect(@result).toBe 'the same'

        describe '- input foo', ->
            Given -> @input = foo

        describe '- input bar', ->
            Given -> @input = bar

Would it be possible to make an Invariant enough to run the code inside all affected describe blocks?

I am not sure I agree, but I do understand that a test branch with no Then statements can be confusing.
