/Users/gabeodess/Sites/share_coffee/test/jobs/create_shippo_transaction_job_test.rb:15: warning: toplevel constant STORE referenced by Shippo::Transaction::STORE

When I run my test suite, I would like my Transaction class to have a constant "STORE" that will keep all Transaction records created during that test.

The warnings in text_output.txt suggest I'm going about this the wrong way, but I'm not sure what I'm doing wrong or what to do differently.

Can someone help me?
