       1) Develop Greenwood With:
        Default Greenwood Configuration and Workspace
          Develop command with generic video container format (.mp4) behavior
            should return the correct content length:
      AssertionError: expected undefined to equal '2498461'

2. [x] Add test case for etag header
3. [x] Finalize testing / clean up consoles and comments
4. [x] Probably a good idea to make sure this and the disable cache work around are documented somewhere - already covered! - http://localhost:1984/about/how-it-works/#cli
