ruby-on-rails - 耙统计和黄瓜

Question

我在 Rails 项目中使用 Cucumber 和 RSpec。当我使用“rake stats”任务时，我得到以下信息：

+----------------------+-------+-------+---------+---------+-----+-------+
| 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 添加了它的统计信息（参见模型、视图、控制器和辅助规范）。
但我没有黄瓜的。我怎样才能将它们添加到我的 rake stats 中？

Answer 1

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之前将您的黄瓜功能目录添加到那里。

#
# 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')

Answer 2

为什么猴子要那样修补宝石？每次更新 rspec-rails 时，您都必须为其添加修复程序。只需在本地扩展任务，如下所示：

echo "# Adding Cucumber features to be reported by the command:
# rake stats
# But e.g. 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

仅供参考，Lichtamberg 和 Damien MATHIEU 这适用于 rspec 2。但是，这些特定于轨道的 rake 任务不是 rspec gem 本身的一部分，而是 rspec-rails gem 的一部分。

PS 这一切都用 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 进行了测试，它可能适用于旧版本，也可能不适用于旧版本其中。

这是一个适用于 Turnip 和 RSpec 2 的版本

I copy paste my custom set up for RSpec 1:

Answer 5

尽管这是一个非常古老的问题，但在谷歌搜索“rails rake stats cucumber”时仍然是第一个问题，并且答案具有误导性或已过时。

对于未来的谷歌人，你需要做的就是运行

$ rails generate cucumber:install

这将创建必要的文件，特别是在输出lib/tasks/cucumber.rake中添加“Cucumber Features”的文件。rake stats
