def <<(expectation)
  @expectations << expectation
end

#call(*args) ⇒ Object

Invoke the expectations for a given set of arguments.

First, look for an expectation that matches the arguements and is eligible to be called. Failing that, look for a expectation that matches the arguments (at this point it will be ineligible, but at least we will get a good failure message). Finally, check for expectations that don’t have any argument matching criteria.

end

#defaultify_expectation(exp) ⇒ Object
