Hiya all,
I've got a quick question related to RSpec. I was test-driving some code and
ended up in an endless loop. I was surprised by this, but traced it down to the
mock not failing on additional calls but only in the end. Let me explain.
I was writing code like this:
subject.wrapper.should_receive(:window_list).exactly(4).times.and_return {
counter = counter + 1
counter >= 4 ? [ "new window" ] : []
}
The idea was that it would call the code-block 4 times exactly and then return
a new value (and thus stop calling it). As the code to implement wasn't there
yet, it led to a recursive call. I had expected RSpec to stop after 4 calls
though, as I had instructed the mock that I expected exactly 4 calls.
I added a new test in RSpec itself in precision_counts_spec.rb:
it "fails when a method is called more than n times, but fails within the
method call" do
@mock.should_receive(:random_call).exactly(1).times
lambda do
@mock.random_call
@mock.random_call
end.should raise_error(RSpec::Mocks::MockExpectationError)
end
which failed :( (or it failed to fail and therefore failed!)
It would be nice if it would fail. Is there any reason for not failing already
at this point in time?
(I'm using RSpec 2.6-0. I quickly browsed the latest and didn't see this
changed)
Thanks,
Bas
