Where to put test files that get created. Ruby directory structure

Question

Say I'm writing an integration test that reads in a CSV and outputs a CSV with some changes in the data. Where do I put this test file in a Ruby project? Is there some convention for where temporary files that get created in tests go that eventually get torn down or delete?

Say my project structure is simple:

--root
   --app
     --promotions
   --spec
   Gemfile
   Gemfile.lock

听起来像Dir.mktmpdir的理想人选。
