耙统计和黄瓜
我在Rails项目中使用Cucumber和RSpec。 当我使用“rake stats”任务时，我得到以下内容：
+----------------------+-------+-------+---------+---------+-----+-------+ | Name | Lines | LOC | Classes | Methods | M/C | LOC/M | +----------------------+-------+-------+---------+---------+-----+-------+ | Controllers | 948 | 761 | 21 | 87 | 4 | 6 | | Helpers | 212 | 175 | 0 | 24 | 0 | 5 | | Models | 912 | 741 | 28 | 72 | 2 | 8 | | Libraries | 305 | 211 | 1 | 25 | 25 | 6 | | Model specs | 978 | 797 | 0 | 1 | 0 | 795 | | View specs | 270 | 227 | 0 | 0 | 0 | 0 | | Controller specs | 1144 | 944 | 0 | 4 | 0 | 234 | | Helper specs | 154 | 116 | 0 | 0 | 0 | 0 | +----------------------+-------+-------+---------+---------+-----+-------+ | Total | 4923 | 3972 | 50 | 213 | 4 | 16 | +----------------------+-------+-------+---------+---------+-----+-------+ Code LOC: 1888 Test LOC: 2084 Code to Test Ratio: 1:1.1 所以rspec添加了它的统计数据（参见模型，视图，控制器和帮助器规范）。
但我没有黄瓜。 我怎么能将它们添加到我的rake统计数据中？
RSpec创建一个lib/tasks/rspec.rake文件。 并重新定义其中的stats目录。
在该文件的第108行，您将看到：
# Setup specs for stats task :statsetup do require 'code_statistics' ::STATS_DIRECTORIES << %w(Model\ specs spec/models) if File.exist?('spec/models') ::STATS_DIRECTORIES << %w(View\ specs spec/views) if File.exist?('spec/views') .... end
您只需要在任务结束前添加黄瓜function目录。
# # Adding Cucumber features to the stats # ::STATS_DIRECTORIES << %w(Cucumber\ features features) if File.exist?('features') ::CodeStatistics::TEST_TYPES << "Cucumber features" if File.exist?('features')
为什么猴子像那样修补gem？ 每次更新rspec-rails时都必须为其添加修复程序。 只需使用以下内容在本地扩展任务：
echo "# Adding Cucumber features to be reported by the command: # rake stats # But eg in production environment we probably don't have rspec-rails, nor it's # statsetup task, we could extend. So lets check if stasetup is available and only # then extend it. If it isn't then just do nothing. if Rake::Task.task_defined? 'spec:statsetup' Rake::Task['spec:statsetup'].enhance do require 'rails/code_statistics' ::STATS_DIRECTORIES << %w(Cucumber\ features features) if File.exist?('features') ::CodeStatistics::TEST_TYPES << 'Cucumber features' if File.exist?('features') end end" > lib/tasks/cucumber_stats.rake
而FYI Lichtamberg和Damien MATHIEU这对rspec 2来说效果很好。但是这些rails特定的rake任务不属于rspec gem本身，而是rspec-rails gem的一部分。
PS这一切都是用ruby 1.9.2p180（2011-02-18修订版30909）[i686-linux]，rails 3.0.8，rspec 2.6.0和rspec-rails 2.6.1测试的，它可能会也可能不适用于旧版本他们
这是一个适用于Turnip和RSpec 2的版本

虽然这是一个非常古老的问题，但它仍然是谷歌搜索“rails rake stats cucumber”时的第一个，答案是误导或过时的。
对于未来的googlers，您需要做的就是运行
$ rails generate cucumber:install
这将创建必要的文件，特别是lib/tasks/cucumber.rake文件，它将“Cucumber Features”添加到rake stats输出中。
