Groovy HTTPBuilder嘲笑响应 [英] Groovy HTTPBuilder Mocking the Response

问题描述

该服务将使用HTTPBuilder来请求一些来自某个服务的响应URL。 HTTPBuilder请求只需要检查响应是否成功或失败。服务实现将如下简单：

  boolean isOk（）{
 httpBuilder.request（GET） {
 response.success = {return true} 
 response.failure = {return false} 
} 
} 
  

所以，我希望能够模拟HTTPBuilder，以便在测试中将响应设置为成功/失败，这样我就可以断言我的服务的 isOk 方法在响应成功时返回True，当响应失败时返回False。

任何一个帮助我可以如何嘲笑HTTPBuilder请求并在GroovyTestCase中设置响应？

解决方案

这是一个模拟 HttpBuilder 将处理您的测试用例：

  class MockHttpBuilder {
 def result 
 def requestDelegate = [response：[：]] 
 
 def request（方法方法，Closure体）{ 
 body.delegate = requestDelegate 
 body.call（）
 if（result）
 requestDelegate.response.success（）
 else 
 requestDelegate.response。失败（）
} 
} 
  

如果结果字段为true，它会调用成功闭包，否则失败。

编辑：下面是一个使用MockFor代替模拟类的例子：

  import groovy.mock.interceptor.MockFor 
 $ b $ def requestDelegate = [response：[：]] 
 def mock = new MockFor（HttpBuilder）
 mock.demand.request {方法方法，闭包体 - > 
 body.delegate = requestDelegate 
ody.call（）
 requestDelegate.response.success（）//或失败，取决于被测试的内容
} 
 mock.use {
 assert isOk（）== true 
} 
  

I am trying to figure out how to write my Test cases for a service I am going to write.

The service will use HTTPBuilder to request a response from some URL. The HTTPBuilder request only needs to check the response for a success or failure. The service implementation will be be something as simple as:

boolean isOk() {
    httpBuilder.request(GET) {
        response.success = { return true }
        response.failure = { return false }
    }
}

So, I want to be able to mock the HTTPBuilder so that I can set the response to be either success/failure in my test so I can assert that my service's isOk method returns True when the response is a success and False, when the response is a failure.

Can any one help with how I can mock the HTTPBuilder request and set the response in a GroovyTestCase?

解决方案

Here's a minimal example of a mock HttpBuilder that will handle your test case:

class MockHttpBuilder {
    def result
    def requestDelegate = [response: [:]]

    def request(Method method, Closure body) {
        body.delegate = requestDelegate
        body.call()
        if (result)
            requestDelegate.response.success()
        else
            requestDelegate.response.failure()
    }
}

If the result field is true, it'll invoke the success closure, otherwise failure.

EDIT: Here's an example using MockFor instead of a mock class:

import groovy.mock.interceptor.MockFor

def requestDelegate = [response: [:]]
def mock = new MockFor(HttpBuilder)
mock.demand.request { Method method, Closure body ->
    body.delegate = requestDelegate
    body.call()
    requestDelegate.response.success() // or failure depending on what's being tested
}
mock.use {
    assert isOk() == true
}
