It appears that the only discrepancy on this test is that passcod/homebrew-cask/adium is not shortened into passcod/cask/adium. Not sure why.

@alebcay that's an intentional test failure -- the test string showed the desired output.

I've updated the PR. The remaining failures have to do with the test suite itself (I think).

[rolandwalker]

There's a new code release -- brew update && brew upgrade brew-cask should fix the problem.
