= ZenTest home :: https://github.com/seattlerb/zentest rdoc :: http://docs.seattlerb.org/ZenTest == DESCRIPTION ZenTest provides 4 different tools: zentest, unit_diff, autotest, and multiruby. 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 Minitest or Test::Unit. There is enough evidence to show that this is still proving useful to users, so it stays. unit_diff is a command-line filter to diff expected results from actual results and allow you to quickly see exactly what is wrong. Do note that minitest 2.2+ provides an enhanced assert_equal obviating the need for unit_diff 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! Use multiruby_setup to manage your installed versions. *NOTE:* The next major release of zentest will not include autotest (use minitest-autotest instead) and multiruby will use rbenv / ruby-build for version management. == FEATURES * Scans your ruby code and tests and generates missing methods for you. * Includes a very helpful filter for Test/Spec output called unit_diff. * Continually and intelligently test only those files you change with autotest. * Test against multiple versions with multiruby. * Includes a LinuxJournal article on testing with ZenTest written by Pat Eyler. * See also: http://blog.zenspider.com/archives/zentest/ * See also: http://blog.segment7.net/articles/category/zentest == STRATEGERY There are two strategeries intended for ZenTest: test conformance auditing and rapid XP. For auditing, ZenTest provides an excellent means of finding methods that have slipped through the testing process. I've run it against my own software and found I missed a lot in a well tested package. Writing those tests found 4 bugs I had no idea existed. ZenTest can also be used to evaluate generated code and execute your tests, allowing for very rapid development of both tests and implementation. == AUTOTEST TIPS Setting up your project with a custom setup is easily done by creating a ".autotest" file in your project. Here is an example of adding some plugins, using minitest as your test library, and running rcov on full passes: require 'autotest/restart' Autotest.add_hook :initialize do |at| at.testlib = "minitest/autorun" end Autotest.add_hook :all_good do |at| system "rake rcov_info" end if ENV['RCOV'] Do note, since minitest ships with ruby19, if you want to use the latest minitest gem you need to ensure that the gem activation occurs! To do this, add the gem activation and the proper require to a separate file (like ".minitest.rb" or even a test helper if you have one) and use that for your testlib instead: .minitest.rb: gem "minitest" require "minitest/autorun" .autotest: Autotest.add_hook :initialize do |at| at.testlib = ".minitest" end If you prefer to suffix test files with "_test.rb" (instead of the default which prefixes test files with "test_") you can change the mapping by installing the autotest-suffix plugin. To do this first install the autotest-suffix gem: $ gem install autotest-suffix Then add the following to the ".autotest" file: require "autotest/suffix" If you prefer minitest/spec to minitest/unit, you can still use autotest by installing the autotest-spec plugin. To do this first install the autotest-spec gem: $ gem install autotest-spec Then add the following to the ".autotest" file: require "autotest/spec" == SYNOPSIS ZenTest MyProject.rb TestMyProject.rb > missing.rb ./TestMyProject.rb | unit_diff autotest multiruby_setup mri:svn:current multiruby ./TestMyProject.rb == Windows and Color Read this: http://blog.mmediasys.com/2010/11/24/we-all-love-colors/ == REQUIREMENTS * Ruby 1.8+, JRuby 1.1.2+, or rubinius * A test/spec framework of your choice. * Hoe (development) * rubygems, 1.8+ * diff.exe on windows.
