Are tests not written correctly?

In trying to update the solution for #52, I ran across my updates not passing the tests. First up, the [test](https://github.com/dthree/vorpal/blob/master/test/vorpal.js#L75) says that its missing the required option --required. I'm not sure if I actually broke something, or if the test just wasn't written properly. It appears that while the fixture doesn't pass any options, the [command](https://github.com/dthree/vorpal/blob/master/test/vorpal.js#L36) actually wants the `--required` option, it just wasn't provided.

Thoughts? Is this test written correctly?
