This simple framework allows you to assert things that should happen tomorrow*. For example:

assert_tomorrow { Time.now.wday == 2 } # => :passed
                                       # assuming today is Monday (i.e. wday == 1)

Another example shows that the time will never be the same again:

today = Time.now
assert_tomorrow { Time.now == today } # => :failed
