Title: CLI spits a clean error when path/js input does not exist

Basically, a simple error message is presented to the CLI user instead of fs thrown exception if the file or path to be tested does not exist. For example: mocha dajlksdj spits an error :).

I believe more cleanup work should be made in the CLI area. We should consider adding some tests.
