DESCRIPTION:

This is a quick and dirty tool to compare test time deltas between two runs by comparing verbose run output.

FEATURES/PROBLEMS:

SYNOPSIS:

% rake TESTOPTS=-v > original_test_run.log
# make some changes to speed things up (or not)
% rake TESTOPTS=-v > new_test_run.log
% minitest_compare original_test_run.log new_test_run.log | head -50
Skipped lines   = 48
Total records   = 4301
Skipped records = 0
