Add functions for reporting new test result data to the user.
Add functions for reporting new test result data to the user.

These functions are not as 'clean' as they could be (i.e. printing
directly to stdout), but it was more obscure to write them in a
generalized fashion and the code doesn't benefit from such
generalization currently (nor is expected to).

Also emoji.
