In that repo +exercises may have a [.json file][problem-specifications-leap-json] that +contains common test data. Some of our local exercises have an +[intermediary program][local-leap-gen] that takes the problem specification +JSON and turns in into Go structs that are fed into the `_test.go` +file.
