用于测试的 Square 改造服务器模拟 [英] Square retrofit server mock for testing

问题描述

在使用 square 改造框架时模拟服务器进行测试的最佳方法是什么.>

可能的方法:

1. 创建一个新的改造 client 并在 RestAdapter.Builder().setClient() 中设置它.这涉及解析 Request 对象并将 json 作为 Response 对象返回.

2. 将此带注释的接口实现为模拟类，并使用它代替 RestAdapter.create() 提供的版本(不会测试 gson 序列化)

3. ?

理想情况下，我希望模拟服务器提供 json 响应，以便我可以同时测试 gson 序列化.

任何示例将不胜感激.

解决方案

我决定尝试方法一如下

public class MockClient 实现 Client {@覆盖公共响应执行(请求请求)抛出 IOException {Uri uri = Uri.parse(request.getUrl());Log.d("模拟服务器", "获取 uri:" + uri.toString());字符串 responseString = "";if(uri.getPath().equals("/path/of/interest")) {responseString = "此处为 JSON 字符串";} 别的 {responseString = "其他 JSON 响应字符串";}return new Response(request.getUrl(), 200, "nothing", Collections.EMPTY_LIST, new TypedByteArray("application/json", responseString.getBytes()));}}

并通过以下方式使用它:

RestAdapter.Builder builder = new RestAdapter.Builder();builder.setClient(new MockClient());

它运行良好，让您无需联系真实服务器即可测试您的 json 字符串！

What's the best way to mock a server for testing when using the square retrofit framework.

Potential ways:

1. Create a new retrofit client and set it in the RestAdapter.Builder().setClient(). This involves parsing the Request object and returning the json as a Response object.

2. Implement this annotated interface as a mock class and use that in place of the version provided by RestAdapter.create() (wont test gson serialisation)

3. ?

Ideally I want to have the mocked server provide json responses so I can test the gson serialisation at the same time.

Any examples would be greatly appreciated.

解决方案

I decided to try method 1 as follows

public class MockClient implements Client {

    @Override
    public Response execute(Request request) throws IOException {
        Uri uri = Uri.parse(request.getUrl());

        Log.d("MOCK SERVER", "fetching uri: " + uri.toString());

        String responseString = "";

        if(uri.getPath().equals("/path/of/interest")) {
            responseString = "JSON STRING HERE";
        } else {
            responseString = "OTHER JSON RESPONSE STRING";
        }

        return new Response(request.getUrl(), 200, "nothing", Collections.EMPTY_LIST, new TypedByteArray("application/json", responseString.getBytes()));
    }
}

And using it by:

RestAdapter.Builder builder = new RestAdapter.Builder();
builder.setClient(new MockClient());

It works well and allows you to test your json strings without having to contact the real server!
