I deleted the `test_sphero.rb` because in the test calss `TestSphero` you were actually testing `Sphero::Request` and I thought it's better to have `test_request.rb` and `TestRequest` which is directly testing the request-related methods and behaviors in via some fine-grained tests! The better thing would be to also move those two tests that you had there to this new class as well! BTW the first one of those tests `test_ping_checksum` was failing! I'll fix it when I add those to this new set of tests as well!
