Sorry, British idiom. It means much the same as "strawman".

It doesn't have to be ert tests, but ert is designed to perform a series 
of tests and produce a report about each test, so it makes sense.

Because I want to be able to unpack a windows distribution and run the 
function. admin isn't included in the distribution (as far as I can 
tell), just the repository. I can do this by hand, but then it's easier 
to make mistakes. I'd like to be able to start Emacs, run M-x 
feature-test, and if everything passes all is good.

If this offends your sense of cleanliness, which I'd understand, it 
could equally go in `data-directory'.
