使用在轨道上使用红宝石搭建的黄瓜测试api

我是黄瓜测试的新手。我试图测试一个简单的api，根据请求获取“/ main/state_list”将返回json中的状态列表。使用在轨道上使用红宝石搭建的黄瓜测试api

我.feature文件

Feature: Check if valid states are returned in json 
In order to select a state 
As a user 
I want to know if valid states are returned in json 

Scenario: Get list of states 
Given A GET request is made 
Then the result should be list of states in JSON: 
""" 
[{"state":"California","_id":"4fbca64718a7ad0a68000003"}, 
{"state":"Georgia","_id":"4fbca69618a7ad0a68000005"}] 
"""

我.RB步骤文件

Given /^A GET request is made$/ do 
get "/main/state_list" 
end 
Then /^the result should be list of states in JSON:$/ do |str| 
json_data=JSON.parse(last_response.body) 
json_data.should == JSON.parse(str) 
end

我的控制器代码

def state_list 
@states= State.all 
render :json => @states.to_json 
end

当我访问的URL直接在浏览器我得到的输出正确

当我在我的cmd中运行黄瓜时，出现此错误。基本上空的响应被发送。
