Test files are not in _test package

[bbengfort]

In order to access the names variable in tests (which is generally unexported) we need to either:

1. Clone the variable definition into the tests
2. Create an export_test.go file with the exports

To avoid this, for now our _gen_test.go files are in the top level package so the resolution doesn't have to be performed; however, we want to ensure that we have black box testing so this issue is about refactoring to fix it.
