How to mock a HTTP response
提问by
I'm a newbie to Java Unit test. The issue I'm facing is that I need to develop a JUnit test to send requests to a server'API to test two methods: addUserand deleteUser. If I want to add/delete a user from the server, I need to get an authentication token from the server; However, due to some issue on the server side, I currently can't get a valid token. So what comes to my mind, is to mock the server's behavior that if the server receives requests from the Unit test, it could response with a JSON data which indicates the status of the add/delete-user operations.
我是 Java 单元测试的新手。我面临的问题是我需要开发一个 JUnit 测试来将请求发送到服务器的 API 以测试两种方法：addUser和deleteUser. 如果我想从服务器添加/删除用户，我需要从服务器获取身份验证令牌；但是，由于服务器端的一些问题，我目前无法获得有效的令牌。所以我想到的是模拟服务器的行为，如果服务器收到来自单元测试的请求，它可以响应一个 JSON 数据，指示添加/删除用户操作的状态。
Because I'm totally new to JUnit. I have no clue how to implement the operation. So my question is what is probably the easiest way to apply the mock?
因为我对 JUnit 完全陌生。我不知道如何实施该操作。所以我的问题是应用模拟最简单的方法是什么？

You can do it by using the HTTP Unit Testing from Google.
您可以使用Google的HTTP 单元测试来实现。
In order to generate a simple HTTP response you can use this code :
为了生成简单的 HTTP 响应，您可以使用以下代码：
HttpTransport transport = new MockHttpTransport();
HttpRequest request = transport.createRequestFactory().buildGetRequest(HttpTesting.SIMPLE_GENERIC_URL);
HttpResponse response = request.execute();
You can also customize your testing by overriding the implementation of the MockHttpTransport class.
您还可以通过覆盖 MockHttpTransport 类的实现来自定义您的测试。
You can check herethe repo of this for more details. I think it can be suitable for you.

You can simulate start a test-http-server in your unit-test. There are several frameworks to do it. For example Mockserverand Wiremock.
您可以在单元测试中模拟启动 test-http-server。有几个框架可以做到这一点。例如Mockserver和Wiremock。
