I took a look at the web site but did not see any issue/bug tracker,
so I’m reporting this here.
The mock framework fails to differentiate between messages sent to a
parent class versus a subclass, so some of my expectations fail when I
assert some expectation on a parent. Here’s code to show it:
cremes$ cat c.rb
class A
end
class B < A
end
class C
def foo
a = A.new
b = B.new
end
end
cremes$ cat c_spec.rb
require ‘rubygems’
require ‘spec’
require ‘c’
describe C, “mock” do
it “should incorrectly pick up message sent to parent class as a
subclass err” do
A.should_receive(:new).once
c = C.new
c.foo
end
end
cremes$ spec c_spec.rb
F
NoMethodError in ‘C mock should incorrectly pick up message sent to
parent class as a subclass err’
undefined method new' for B:Class ./c.rb:10:infoo’
./c_spec.rb:9:

If I capture the exception thrown here, it is at lib/spec/mocks/
proxy.rb line 75. I’d provide a patch if I knew how to fix it!
