Hey speclers,
My spec-fu is failing me on a message expectation in which I would like to
verify that the block passed to a certain method yields the proper
value. I would like to be able to say something like:
def bar
# .. some code
foo do
'bar' # want to verify this value
end
end
describe 'bar' do
it 'calls foo with proper block' do
should_receive(:foo).with(block_yielding('bar'))
end
end
The problem I've been banging my head against is the fact that I can't
seem to capture the passed block using this notation:
should_receive(:foo) { |*args, &block|
yield.should == 'bar' # breaks
block.call.should == 'bar' # no dice
}
I believe the lack of ability to use this notation comes down to a ruby
limitation, but I'm not sure. If that's the case, then we would need a
specific argument expectation (along the lines of my suggestion) that
executes in a context in which it can call the block.
Am I missing something obvious here, or does rspec currently not allow
for this easily? If not, let's discuss how it should look and I can
work on adding feature.
Cheers,
Paul
