[rspec-users] mock expectation in before block

[Andrea Fazzi]

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
