1de9afcd 4# most of the constructs we'll be testing for. (This comment is
8bdd21ca 5# probably obsolete on the avoidance side, though still current
1de9afcd 6# on the peculiarity side.)

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.
13
14# In which case, we need to stop t/TEST actually running tests, as all
15# t/harness needs are its subroutines.
