My first attempt at determining the most popular testing modules left out Test.pm. Whoops! I've fixed that.
Out of almost 60,000 test programs, it turns out Test.pm is used 8,937 times. Now that I have a file which lists how many times each test module is used, I can start examining my extracted CPAN to determine what percentage of modules actually use the Test::Builder framework. This is done via heuristics, so the numbers are likely to be slightly off, but I've done enough work with test suites (including a lot of work on CPAN test suites I haven't written), that I don't think these numbers are *too* far off. Uses Count Percent ------------------------------ Test::Builder 47934 81.30% Non-builder 1107 1.88% Unknown 642 1.09% Test.pm 8937 15.16% (Unknown represents modules I couldn't find the paths to). So basically, if you put in a special case for Test.pm, you will likely be able to write special test code for almost 97% of CPAN modules.
