我正在尝试让黄瓜在我的Mac上运行以测试ruby脚本。我使用带有rails的黄瓜并且从来没有遇到过设置它的问题，但是对于我想要测试的ruby脚本来说它似乎有一个问题。
脚本背景：我创建了一个通过TCPServer连接提供mysql数据的脚本，我希望能够测试这个功能。理想情况下，我启动脚本以便接受传入连接，并根据我尝试获取的内容提出错误或数据终点。
这是我所拥有的，错误低于设置：
特征性/支撑性/ env.rb require_relative File.expand_path（'../../../ lib / requirements'， FILE ）

require "rspec"

And There is MYSQL data
When converted to hash
And and /mysql location is hit
Then the data is show in JSON

你可以使用rake来运行黄瓜测试，我将它用于我写的宝石。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
