  17 # TAP support: the following situations should be flagged as errors:
  18 #  - unmatched test plan (too few tests run)
  19 #  - multiple test plans
  20 #  - missing test plan
  21 #  - misplaced test plan (tests run after a late plan)
  22 # Checks about unplanned tests are performed in 'tap-unplanned.test'
  23 # and 'tap-skip-whole-badcount.test'.  More checks about corner-cases
  24 # in TAP plans are performed in 'tap-plan-corner.test'.
