ZenTest 3.2.0
ZenTest provides 4 different tools and 1 library: zentest, unit_diff, autotest, multiruby, and Test::Rails.
ZenTest scans your target and unit-test code and writes your missing code based on simple naming rules, enabling XP at a much quicker pace. ZenTest only works with Ruby and Test::Unit.
unit_diff is a command-line filter to diff expected results from actual results and allow you to quickly see exactly what is wrong.
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.
multiruby runs anything you want on multiple versions of ruby. Great for compatibility checking!
Test::Rails helps you build industrial-strength Rails code.
STRATEGERY
There are two strategeries intended for ZenTest: test conformance auditing and rapid XP.
