I went to implement these and realized I wasn't paying attention to the 
interaction between them.

OK, so:

How about a separate 'test-run' which is like test-apply but always
creates a new runner (using the current factory) to do so, and then
finalizes it.

  (test-run spec ... form)

with the added feature that the caller may supply zero (0) specs, in which
case all tests are run (which is a special case, because the degenerate
case which would cause no tests to be run)

and then test-apply never creates a group contour, and either (a SRFI
specification time choice)  (1) only makes sense when there is already a

  (test-apply spec ... form)

(useful for doing the inverse of test-skip)

or, (2) always takes a runner argument:

  (test-apply runner spec ... form)

and in either case, at least one spec must be supplied.
