What RSpec approach could I use for this

Background: So I have roughly:

class A
def calculate_input_datetimes
# do stuff to calculate datetimes - then for each one identified
process_datetimes(my_datetime_start, my_datetime_end)
end

def process_datetimes(input_datetime_start, input_datetime_end)
# do stuff
end
end

So:

  • I want to test that calculate_input_datetimes algorithms are working
    and calculating the correct datetimes to pass to process_datetimes
  • I know I can STUB out process_datetimes so that it’s code won’t be
    involved in the test

QUESTION: How can I setup the rspec test however so I can specifically
test that the correct datestimes were attempted to be passed over to
process_datetimes, So for a given spec test that process_datetimes was
called three (3) times say with the following parameters passed:

  • 2012-03-03T00:00:00+00:00, 2012-03-09T23:59:59+00:00
  • 2012-03-10T00:00:00+00:00, 2012-03-16T23:59:59+00:00
  • 2012-03-17T00:00:00+00:00, 2012-03-23T23:59:59+00:00

thanks
