8 # t/TEST and t/harness need to share code. The logical way to do this would be
9 # to have the common code in a file both require or use. However, t/TEST needs
10 # to still work, to generate test results, even if require isn't working, so
11 # we cannot do that. t/harness has no such restriction, so it is quite
12 # acceptable to have it require t/TEST.
14 # In which case, we need to stop t/TEST actually running tests, as all
15 # t/harness needs are its subroutines.
