Mock expectation in before block

Hi all,

consider a class Foo that send, in its constructor, some message to an
object of class Bar:

class Foo
def initialize(bar)
@bar = bar
@bar.some_message
end

end

Now, in order to test Foo, I’d like to decouple it from Bar mocking bar
object, so:

describe Foo do

before do
@bar = mock(‘bar’)
@bar.should_receive(:some_message)
@foo = Foo.new(bar)
end

it ‘should …’
it ‘should …’

end

The question is: is it appropriate to put a mock expectation inside a
before block? Or mock expectations are relegated to example blocks?

Thanks in advance.
Andrea

Hi Andrea,

I generally put stub! calls in the before block and then have the mock
expectation in the example block.

Thank you for your answer Matt. I think I’ve cought the point.

Stub methods return canned responses so they are not intended to
underline interactions between the mock object and the object under
testing.

Thank you again.
