OK, but there are numerous problems with this test ...

1. You're supposed to follow the MVC pattern and not do echos from within the controller.
2. You're also manually calling `set_status_header()` in a CLI application - why?
3. You're testing with 2.1.3, which is WAY behind the state of the develop branch.

Granted, 1 could be ignored for a CLI application, but still - these 2 points are mutually exclusive in terms of proper/sane usage.
