Up to now I could run tests as show here: ["using" module within the same file where module was defined - #3 by PetrKryslUCSD](https://discourse.julialang.org/t/using-module-within-the-same-file-where-module-was-defined/6211/3)

This morning this wouldn’t run with 0.7 and I have to do “using .mod” instead of “using mod”. Also, I cannot now do “`using Base.Test`”, since apparently `Test` was moved.

With these 2 changes I cannot get my package to pass tests for both 0.6 and 0.7.
