Further fixes -

- All test files have been renamed to their respective <package>_test name,
    this is done in accordance with
      - https://github.com/golang/go/wiki/CodeReviewComments#import-dot
        imports are largely used in testing, but to avoid namespace collision
        and circular dependencies

  - Never use _* in package names other than "_test" change fragment_v1 to expose
    fragment just like 'gopkg.in/check.v1'
