Flay analyzes code for structural similarities. Differences in literal values, variable, class, method names, whitespace, programming style, braces vs do/end, etc are all ignored. Making this totally rad.

Flog reports the most tortured code in an easy to read pain report. The higher the score, the more pain the code is in.

Analyze code for potentially uncalled / dead methods, now with auto-removal.

Hunting down random test failures can be very very difficult, sometimes impossible, but minitest-bisect makes it easy. minitest-bisect helps you isolate and debug random test failures. If your tests only fail randomly, you can reproduce the error consistently by using `--seed <num>`, but what then? How do you figure out which combination of tests out of hundreds are responsible for the failure? You know which test is failing, but what others are causing it to fail or were helping it succeed in a different order? That's what minitest-bisect does best.

autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests. minitest-autotest is the latest incarnation of the venerable and wise autotest. This time, it talks to minitest via minitest-server. As a result, there is no output parsing. There are no regexps to tweak. There's no cruft or overhead.

Runs (Get it? It's fast!) your tests and makes it easier to rerun individual failures.
