如何在Rails 3.1中设置Cucumber，Guard & Spork？

Question

我正在尝试设置黄瓜、rspec、guard和spork。我已经让rspec工作得很好了，但是cucumber崩溃了，跟踪如下。

我已经试着设置了几次，rails g cucumber:install --spork spork cucumber --boostrap等...不走运。

Gems: rails (3.1.3) guard (0.10.0) guard-bundler (0.1.3) guard-cucumber (0.7.4，0.7.3) guard-rails (0.0.3) guard-rspec (0.6.0，0.5.2) guard-spork (0.5.1，0.5.0) cucumber (1.1.4) cucumber-rails (1.2.1) spork (0.9.0)

Done.

Answer 1

我终于解决了这个问题，在处理了通过我的防护文件传递给黄瓜的标志后，我能够解决冲突的标志，而不是覆盖我的cucumber.yml标志。

工作保护文件

guard 'cucumber', :cli => "--drb" do
  watch(%r{^features/.+\.feature$})
  watch(%r{^features/support/.+$})          { 'features' }
  watch(%r{^features/step_definitions/(.+)_steps\.rb$}) { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'features' }
end

cucumber.yml

<%
rerun = File.file?('rerun.txt') ? IO.read('rerun.txt') : ""
rerun_opts = rerun.to_s.strip.empty? ? "--format #{ENV['CUCUMBER_FORMAT'] || 'progress'} features" : "--format #{ENV['CUCUMBER_FORMAT'] || 'pretty'} #{rerun}"
std_opts = "--format #{ENV['CUCUMBER_FORMAT'] || 'pretty'} --strict --tags ~@wip"
%>
default: --drb <%= std_opts %> features
wip: --drb --tags @wip:3 --wip features
rerun: --drb <%= rerun_opts %> --format rerun --out rerun.txt --strict --tags ~@wip

冲突的保护文件

guard 'cucumber', :cli => "--drb --color --format pretty" do
  watch(%r{^features/.+\.feature$})
  watch(%r{^features/support/.+$})          { 'features' }
  watch(%r{^features/step_definitions/(.+)_steps\.rb$}) { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'features' }
end
