如何构建 com.netflix.client.http.httpresponse 对象

Question

我正在写unit test个案例，使用mocking个概念，我是mocking RestClient class 原码：

final HttpResponse response = restClient.executeWithLoadBalancer(request);

在Spock中测试class模拟代码：

restClient.executeWithLoadBalancer(_ as HttpRequest) >> httpResponse

这里我必须构建并设置 httpResponse。如何构建 HttpResponse

Answer 1

作为HttpResponse is an interface and you can't really build or create instance of it.what you can able to do is probably create instance of class that implements this interface. for eg: HttpClientResponse

您可以构建和设置 httpResponse 任何你喜欢的如下，

ClientResponse clientResponse = Mock(ClientResponse)
MultivaluedMapImpl sampleHeaders = new MultivaluedMapImpl()
sampleHeaders.add("name", "test")
clientResponse.getHeaders() >> sampleHeaders
HttpResponse httpResponse = new HttpClientResponse(clientResponse,null,null)

restClient.executeWithLoadBalancer(_ as HttpRequest) >> httpResponse

旁注，要模拟 ClientResponse，您需要在类路径中添加 objenesis。
