重载方法的Groovy单元测试

Question

使用MockFor如何为重载方法编写单元测试。

例如

public HttpResponse execute(HttpUriRequest request, HttpContext context) 

和

public HttpResponse execute(HttpHost target, HttpRequest request) 

我已经写：

 def responseMocker = new MockFor(HttpResponse.class) 
     HttpResponse response = responseMocker.proxyInstance() 
     def requestMocker = new MockFor(HttpUriRequest.class) 
     def request = requestMocker.proxyInstance() 
     def contextMocker = new MockFor(HttpContext.class) 
     def context = contextMocker.proxyInstance(); 
     def clientMocker = new MockFor(HttpClient.class) 
     clientMocker.demand.execute(request, context) { response } 

     HttpClientSample client = new HttpClientSample(clientMocker.proxyInstance()) 

     assertEquals response, client.execute(request,context) 

上面这个测试失败：

groovy.lang.MissingMethodException：没有签字：方法E：....

Answer 1

你需要指定所要求的方法是这样的：

mock.demand.execute { HttpUriRequest request, HttpContext context -> ... } 
mock.demand.execute { HttpHost target, HttpRequest request -> ... } 

这将绑定所要求的方法，以适当的重载方法签名。
