Groovy HTTPBuilder模拟客户端 [英] Groovy HTTPBuilder Mocking the Client

问题描述

这个问题与这个问题密切相关。不同的是，我想按照推荐的方式来嘲笑客户。因此，我定义了以下HTTPBuilder：

  protected readUrl（）{
 def http = new HTTPBuilder（http ：//example.com）
 def status = http.request（Method.GET，ContentType.JSON）{req  - > 
 response.success = {resp，json  - > 
 result = json.toString（）
 new Success< String>（result）
} 
 response.'401'= {resp  - > 
 final String errMsg =Not Authorized
 new Failed（Failable.Fail.ACCESS_DENIED，errMsg）
} 
 response.failure = {resp  - > 
 final String errMsg =General failure $ {resp.statusLine}
 new Failed（Failable.Fail.UNKNOWN，errMsg）
} 
} 
} 
  

我想要做的是找到一种方法来单元测试这个代码块。如果可能的话，我想嘲笑响应，所以我可以专门设置响应代码。有人可以告诉我一种方法吗？

解决方案

这是我的首选解决方案：

  class MockHTTPBuilder {
 MockHTTPBuilder（string）{} 
 MockHTTPBuilder（）{} 
 def pleaseFail = false 
 def mockData = [] 
 def request（a，b，c）{
 if（pleaseFail）[status：'500'，data：mockData？：It failed :(] 
 else [status：'200'，data：mockData？：'Yay :)] 
} 
} 
  

以下是一些示例用法： http://groovyconsole.appspot.com/script/ 760001

或者，您可以对实际的httpClient实例进行元编程，并使其按预期工作（在测试期间强行失败或传递），但这有点儿更复杂。

This question is closely related to this question. The difference is that I'd like to follow the recommended approach of mocking the client. So, I have the following HTTPBuilder defined:

protected readUrl() {
    def http = new HTTPBuilder("http://example.com")
    def status = http.request(Method.GET, ContentType.JSON) {req ->
        response.success = {resp, json ->
            result = json.toString()
            new Success<String>(result)
        }
        response.'401' = {resp ->
            final String errMsg = "Not Authorized"
            new Failed(Failable.Fail.ACCESS_DENIED, errMsg)
        }
        response.failure = {resp ->
            final String errMsg = "General failure ${resp.statusLine}"
            new Failed(Failable.Fail.UNKNOWN, errMsg)
        }
    }
}

What I'd like to do is find a way to unit test this code block. I wanted to mock the response so I could specifically set the response codes, if possible. Could someone please show me a way to do this?

解决方案

This is my prefered solution:

class MockHTTPBuilder{
    MockHTTPBuilder(string){}
    MockHTTPBuilder(){}
    def pleaseFail = false
    def mockData = []
    def request(a, b, c){
        if(pleaseFail) [status:'500',data: mockData ?: "It failed :("]
        else [status:'200',data: mockData ?: "Yay :)"]
    }
}

Here's some sample usages: http://groovyconsole.appspot.com/script/760001

Alternatively, you can metaprogram the actual httpClient instance and make it behave as expected(forcebly failing or passing during test-time) but that's a little bit more complicated.
