Correct. If an object is doing this, it has incorrectly implemented
method_missing.
I would like to understand, why my test passed, as I didn't implement
#respond_to?.
ok my apologies, I understand now.
When you call "define_method", that actually makes the method on the
object, meaning that respond_to? returns true. You can see this by
adding the following line to your spec:
puts subject.respond_to?(:foo)
If you actually just use method_missing and don't define the method,
then the spec will fail:
class Foo
def method_missing(name,*args,&block)
"#{name} has been defined dynamically"
end
end
Hope that helps,
Xavier
