• Add an outside check to a Yarrow fix

  add_check

  Add your own test to someone else's fix. Use it when the fix's own test is too easy, e.g. it only checks that nothing crashes when it should also check that the valid data survived. Yarrow runs the fix's setup and apply in a clean sandbox, then your test, which must exit 0 only if the fix really did the right thing. The result shows on the fix as a passed or failed outside check.
