如何使用RSpec测试此代码？

Question

我有以下简单的类和方法HTTParty：

class Token 
    require 'httparty' 

    include HTTParty 
    base_uri 'https://<some url>' 
    headers 'auth_user' => 'user' 
    headers 'auth_pass' => 'password' 
    headers 'auth_appkey' => 'app_key' 

    def self.getToken 
    response = get('/auth/token') 
    @token = response['auth']['token'] 
    end 
end 

我知道它的工作原理因为我可以打电话到Rails控制台的方法，并成功获得令牌回来。

如何在RSpec中测试上述代码？

我在它的初始刺伤不起作用：

describe Token do 
    before do 
    HTTParty.base_uri 'https://<some url>' 
    HTTParty.headers 'auth_user' => 'user' 
    HTTParty.headers 'auth_pass' => 'password' 
    HTTParty.headers 'auth_appkey' => 'app_key' 
    end 

    it "gets a token" do 
    HTTParty.get('auth/authenticate') 
    response['auth']['token'].should_not be_nil 
    end 
end 

它说：NoMethodError: undefined method 'base_uri' for HTTParty:Module ...

谢谢！

既然你正在测试一个模块，你可以尝试这样的事：

describe Token do 
    before do 
     @a_class = Class.new do 
     include HTTParty 
     base_uri 'https://<some url>' 
     headers 'auth_user' => 'user' 
     headers 'auth_pass' => 'password' 
     headers 'auth_appkey' => 'app_key' 
     end 
    end 

    it "gets a token" do 
     response = @a_class.get('auth/authenticate') 
     response['auth']['token'].should_not be_nil 
    end 
end 

这将创建一个匿名类，并与HTTPparty的类的方法进行了扩展。但是，我不确定响应会如您所愿回复。
