Question

我有一些我想测试的Grails生产代码，我在这里看到了一些例子，见下文。问题是我在HttpBuilder的客户端部分遇到了MissimgMethodExceptions。这是我想测试的生产代码：

class RunkeeperActivitiesRetrieverService {
    def http = new RESTClient("http://api.runkeeper.com/")

    def getActivities() {
        http.client.clearRequestInterceptors();
        http.client.addRequestInterceptor(new HttpRequestInterceptor() {
            void process(HttpRequest httpRequest, HttpContext httpContext) {
                httpRequest.addHeader('Authorization', 'Bearer xxxxxxxxxx')
            }
        })
        //Do more with the httpBuilder
    }
}

我在这里找到了一些关于模拟HTTPBuilder主题的帮助：Groovy HTTPBuilder Mocking the Response以及一些关于groovy文档中的模拟接口：http://groovy.codehaus.org/Groovy+way+to+implement+interfaces

使用该代码我来到了这个测试代码：

def mock = new MockFor(HTTPBuilder)
def impl = [
    addRequestInterceptor : {HttpRequestInterceptor interceptor -> println "hi 4"+interceptor},
    clearRequestInterceptors : {println "hi 88"}
            ]
def client = impl as HttpClient

mock.demand.getClient {return client}
mock.use{
    service.http = new HTTPBuilder()
    println service.getActivities()
}

不幸的是，我对Groovy的了解太有限，无法解决抛出的异常：groovy.lang.MissingMethodException: No signature of method: $Proxy15.clearRequestInterceptors() is applicable for argument types: () values: []

我在这里缺少什么？

您将impl投射到HttpClient - 似乎未在that interface上定义相关方法。也许你的意思是使用AbstractHttpClient的一些子类。

如何使用MockFor在HttpBuilder上模拟客户端？
