main:Object的未定义方法`before'

Question

我从下面的代码部分得到了上述错误.原因是什么？

 1  require 'spec_helper'
 2
 3  before(:all) do
 4    puts "ServerSpec tests on #{ENV['TARGET_HOST']}"
 5  end

完整错误:

/home/newatson/src/serverspec/spec/cfengine3/common_spec.rb:3:in `<top (required)>': undefined method `before' for main:Object (NoMethodError)

Answer 1

before应在以下范围内实施describe:

require 'spec_helper'

describe "My Tests" do
  before(:all) do
    puts "ServerSpec tests on #{ENV['TARGET_HOST']}"
  end
end

祝好运!
