I had, for historic reasons, a setup on a group of specs:
before(:all) do
@contents = [%w(this that), %w(this other)]
FasterCSV.stub!(:open).and_return(@contents)
@filename = ''test_filename''
end
When I ran the single file (spec spec/transformer/csv_spec.rb), all my
specs passed. When I ran the whole project''s specs together (spec
spec/), these failed. Changing before(:all) to before(:each) worked,
but for reasons that are not clear to me. The before(:all) approach
didn''t work because the FasterCSV stub wasn''t being set.
Can someone explain why there would be different behavior between
running one file and many files and before(:each) vs. before(:all)?
As far as I understand it, I thought before(:all) was supposed to
always run before a group of specs. Is it possible that a before
(:all) doesn''t work right when calling multiple/all specs at the same
time?
Thanks

My rough guess would be that something in one of your other spec files called code that that required or reloaded FasterCSV, which blew away your stub when those other spec files were initialized after after this one.
