The first is doing date calculation using algorithms and the second is delegating responsibility by calling processing dates. Instead you should have a method that just delegates e.g.
def foo calculate_datetimes process_datetimes end Now your test for foo is all about it calling calculate... and then calling process... with the results. (I'll leave it up to you to determine how you pass the results. The actual methods you delegate too now can be tested independently. Your current tests are actually telling you this, because they want to do one thing and then another and that is making them harder to implement HTH Andrew > 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 > > -- > Posted via http://www.ruby-forum.com/. > _______________________________________________ > rspec-users mailing list > rspec-users@rubyforge.org > http://rubyforge.org/mailman/listinfo/rspec-users > -- ------------------------ Andrew Premdas blog.andrew.premdas.org
