ruby-on-rails - cucumber 找不到步骤定义

Question

我的 Cucumber 找不到步骤定义。文件结构(只有 Rails 根目录中的 specs 文件夹)如下所示:

-> specs
   -> features
      -> main_structure.feature
      -> step_definitions
         -> main_structure_steps.rb

这是 main_structure.feature:

Feature: Main structure
  Scenario: Viewing the Structure page
    When I am on the structure page

这是 main_structure_steps.rb:

When(/^I am on the structure page$/) do
  visit '/'
end

现在我像这样运行 cucumber 命令:

→ cucumber spec/features -r features 

我得到这个输出:

Using the default profile...
Feature: Main structure

  Scenario: Viewing the Structure page # spec/features/main_structure.feature:2
    When I am on the structure page    # spec/features/main_structure.feature:3
      Undefined step: "I am on the structure page" (Cucumber::Undefined)
      spec/features/main_structure.feature:3:in `When I am on the structure page'

1 scenario (1 undefined)
1 step (1 undefined)
0m0.229s

You can implement step definitions for undefined steps with these snippets:

When(/^I am on the structure page$/) do
  pending # express the regexp above with the code you wish you had
end

/Users/rudolf/.rvm/gems/ruby-2.0.0-p247@global/gems/minitest-4.7.5/lib/minitest/unit.rb:1037:in `block in process_args': invalid option: -r (OptionParser::InvalidOption)
    from /Users/rudolf/.rvm/gems/ruby-2.0.0-p247@global/gems/minitest-4.7.5/lib/minitest/unit.rb:1016:in `new'
    from /Users/rudolf/.rvm/gems/ruby-2.0.0-p247@global/gems/minitest-4.7.5/lib/minitest/unit.rb:1016:in `process_args'

    from /Users/rudolf/.rvm/gems/ruby-2.0.0-p247@global/gems/minitest-4.7.5/lib/minitest/unit.rb:1059:in `run'
    from /Users/rudolf/.rvm/gems/ruby-2.0.0-p247@global/gems/minitest-4.7.5/lib/minitest/unit.rb:795:in `block in autorun'

底部还有一条错误信息，当我在RubyMine 中运行测试时没有出现。但是在这两种情况下，都找不到步骤定义。这是 Rubymine 的输出:

Testing started at 21:29 ...

如果您需要任何其他信息，请告诉我。

尝试

cucumber spec/features/main_structure.feature -r spec/features
