Cannot source unit tests from unit tests

[bloodnok-marine]

I'd like to be able to source a set of unit tests from a higher-level set of unit tests. Something like this:

. detect/unit
. info/unit
. get/unit
. set/unit

As far as I can see, this is not supported.

I am prepared to create the code and unit tests to make this work and then submit a pull request, but before I do, I'd like to know if there is any philosophical reason not to take this approach.

Thanks.

Well, I updated the code anyway. I have not added unit tests. A pull request will follow.
