main:Object 的未定义方法“之前”

Question

我从下面的代码部分收到上述错误。是什么原因？

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

完整错误：

Answer 1

before 应在 describe:

内实施

require 'spec_helper'

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

祝你好运！

Answer 2

您似乎没有描述您的 class。没有 describe 对象成为接收者并且你有一个 NoMethodError。轻松修复：

describe MyClass do
  before(:all) do
    #
  end
end
