There are those that advocate writing a test case that fails, then
fixing the code until the test case succeeds, then committing the test
case to the test-bed at the same time the code is committed to the
tree.  With the test-case gating the code.

This works well for some thing, but we can't do it universally since
some test-cases would be only for 'rogue' hardware, which can't be
automatically tested.
