我第一次在rails 3中使用黄瓜.

I used cucumber for the first time with rails 3.

宝石文件

group :test do
 gem "rspec"
 gem "rspec-rails"
 gem "database_cleaner"
 gem "spork"
 gem "cucumber",         :git => "git://github.com/aslakhellesoy/cucumber.git"
 gem "cucumber-rails",   :git => "git://github.com/aslakhellesoy/cucumber-rails.git"
 gem "capybara"
 gem "capybara-envjs"
 gem "launchy"
 gem "ruby-debug"
end

并使用发电机安装黄瓜骨架

and used the generator to install the cucumber skeleton

rails generate cucumber:install --rspec --capybara

这会生成一个 cucumber.yml

this generates a 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: <%= std_opts %> features
wip: --tags @wip:3 --wip features
rerun: <%= rerun_opts %> --format rerun --out rerun.txt --strict --tags ~@wip

如果我运行它运行的最简单的功能，但在测试后它会引发异常

if I run the simplest feature it runs through but after the test it raises an exception

$ rake cucumber
bundle exec /Users/www/.rvm/rubies/ruby-1.8.7-p330/bin/ruby -I "/Users/www/.rvm/gems/ruby-1.8.7-p330@my_app/bundler/gems/cucumber-e2df150cc4fd/lib:lib" "/Users/www/.rvm/gems/ruby-1.8.7-p330@my_app/bundler/gems/cucumber-e2df150cc4fd/bin/cucumber"  --profile default

Usage: /Users/www/.rvm/gems/ruby-1.8.7-p330@my_app/bundler/gems/cucumber-e2df150cc4fd/bin/cucumber [options] [-- untouched arguments]

我找不到这个小问题的解决方案，有什么帮助吗?

I can't find the solution for this little problem, any help?

推荐答案

尝试使用 cucumber features 或简单地使用 cucumber 而不是 rake cucumber.

Try using cucumber features or simply cucumber instead of rake cucumber.
