ruby + cucumber可以运行在rubymine的demo

1、ruby 开发工具 rubymine，网上cucumber + java比较多，ruby比较少，所以这些是记录和学习

2、安装好ruby，gem也就安装好了（gem 安装ruby需要的其他模块）

3、项目根目录，命令行输入cucumber --init，初始化cucumber目录，会生成一个文件夹features，和features>step_definitions，features>support

step_definitions文件夹创建我们的search_step.feature文件

Feature: web search

  Scenario Outline: search building
    Given /^ visit a website url <url>$/
    When /^ search build named <building_name>$/
    Then /^ the number <num> should be show in current page$/

    Examples:

      | url                          | building_name | num |
      | "http://bj.jiwu.com/loupan/" | "西山金茂府"       | 99  |

创建search_step.rb，实现step内容

Given('\/^ visit a website url {string}$\/') do |string|
  puts "#{string}"
end

When('\/^ search build named {string}$\/') do |string|
  puts "#{string}"
end

Then('\/^ the number {float} should be show in current page$\/') do |float|
  puts "#{float}"
end

然后就可以运行了
根目录命令行

cucumber --init

第2个运行方法、很上面一样

require 'cucumber'
puts File.join(File.dirname(__FILE__ ), "/features/step_definitions/search_step.feature")

features = File.join(File.dirname(__FILE__ ), "/features/step_definitions/search_step.feature")
runtime = Cucumber::Runtime.new

Cucumber::Cli::Main.new([features]).execute!(runtime)

运行成功

D:\ruby_study2>cucumber --init
   exist   features
   exist   features/step_definitions
   exist   features/support
   exist   features/support/env.rb
Feature: web search

  Scenario Outline: search building                           # features/step_definitions/search_step.feature:3
    Given /^ visit a website url <url>$/                      # features/step_definitions/search_step.feature:4
    When /^ search build named <building_name>$/              # features/step_definitions/search_step.feature:5
    Then /^ the number <num> should be show in current page$/ # features/step_definitions/search_step.feature:6

    Examples:
      | url                          | building_name | num |
http://bj.jiwu.com/loupan/
西山金茂府
99.0
      | "http://bj.jiwu.com/loupan/" | "西山金茂府"       | 99  |

1 scenario (1 passed)
3 steps (3 passed)

比较疑惑的是search_step.rb，和search_step.feature没有require引用，但是已经有了关联，第一个课学习结束
