在 Mac OS X 上用黄瓜测试 ruby（不是 rails）脚本答案

【问题标题】：Testing ruby (not rails) script with cucumber on Mac OS X在 Mac OS X 上用黄瓜测试 ruby（不是 rails）脚本
【发布时间】：2014-03-14 16:00:01
【问题描述】：

我正在尝试让 cucumber 在我的 Mac 上工作以测试 ruby 脚本。我使用带有rails的黄瓜并且在那里设置它从来没有遇到过问题，但似乎只是为我想要测试的ruby脚本创建它时遇到了相当大的问题。

脚本背景：我创建了一个通过 TCPServer 连接提供 mysql 数据的脚本，我希望能够测试此功能。因此，理想情况下，我启动脚本以便它接受传入的连接，并根据我尝试获取的内容显示错误或数据端点。

这是我所拥有的，错误低于设置：

功能/支持/env.rb require_relative File.expand_path('../../../lib/requirements',FILE)

require "capybara/cucumber"
 require 'capybara/dsl'
 require "rspec"

# Capybara.default_driver = :selenium

 Capybara.app_host = 'http://localhost:7125'

 World(Capybara.app = "Api")
 World(Capybara::DSL)
 World(RSpec::Matchers)

功能/rmws.feature

  Feature: Test conversion of mysql output to JSON

   Scenario:
     Given the index page can be reached
     And There is MYSQL data
     When converted to hash
     And and /mysql location is hit
     Then the data is show in JSON

features/step_definitions/rwms_step_definitions.rb

Given(/^the index page can be reached$/) do
  visit 'http://localhost:7125'
  expect(page).to have_content 'This is the index page'
end

Given(/^There is MYSQL data$/) do
  pending # express the regexp above with the code you wish you had
end

When(/^converted to hash$/) do
  pending # express the regexp above with the code you wish you had
end

When(/^and \/mysql location is hit$/) do
  pending # express the regexp above with the code you wish you had
end

Then(/^the data is show in JSON$/) do
  pending # express the regexp above with the code you wish you had
end

输出

   $ cucumber

【解决方案1】：

您可以使用 rake 运行 cucumber 测试，我将它用于我编写的 gem。您可以找到其他文档here

require 'bundler'
require 'rake/clean'

require 'rake/testtask'

require 'cucumber'
require 'cucumber/rake/task' 
require 'rspec/core/rake_task'
Cucumber::Rake::Task.new(:features) do |t|
  t.cucumber_opts = "features --format html -o #{CUKE_RESULTS} --format pretty --no-source -x"
  t.fork = false
end

【讨论】：

我认为 rake 可能会使我目前想做的事情过于复杂（或者这可能是正确的做法）。我的项目中只有我的 features 目录，我想在我尝试做其他任何事情之前让它在最基本的层面上工作。
