如何模拟 REST 服务？
我有一个 maven/mule/spring 开发环境，我在其中构建 REST 服务。我还有一系列 TestNG 测试来验证这些服务。我还希望能够更改服务的响应，返回特定信息或引发异常。这是我可以自动测试更广泛的服务行为。我认为模拟服务是最好的方法，但我找不到任何关于如何模拟 REST 服务的好信息。
我可以查看有关如何模拟 REST Web 服务的任何材料吗？

我想我应该添加一个例子来使问题更加具体。如果我有以下设置：
testA calls serviceA, which then calls serviceB
如果 serviceA 应该返回一个 web 异常到 testA 如果 serviceB 响应错误，我想将一个 mockedServiceB 注入到系统中进行测试，其中 mockedServiceB 总是返回一个错误：
testA calls serviceA, which then calls mockedServiceB (which always returns an error to serviceA)
I have a maven/mule/spring development environment that I build REST services within. I also have a series of TestNG tests to validate these services. I also want the ability to alter the responses from the services, either returning specific information or throw an exception. This was I can automatically test broader behaviours of the services. I figured that mocking the services would be the best approach, but I cannot find any good information on how to mock a REST service.
Is there any material I can review on how to mock a REST web service?
--Update---
I thought I would add an example to make the problem more concrete. If I have the following setup:
testA calls serviceA, which then calls serviceB
If serviceA should return a web exception to testA if serviceB responds with an error, I would like to inject a mockedServiceB in to the system for the test where mockedServiceB always returns an error:
testA calls serviceA, which then calls mockedServiceB (which always returns an error to serviceA)

我遇到了同样的问题，并编写了一个用于模拟 REST 服务的小库： https://github.com/mkotsur/restito< /a>.
你可以尝试一下。
I had the same problem and wrote a small lib for mocking REST services: https://github.com/mkotsur/restito.
You can give it a try.
一般来说，我会将 Mule 配置分段为每个片段一个服务，然后在测试时加载真实服务 A 片段和测试服务 B 片段。测试服务 B 将使用 Mule test: 组件来模拟好的或坏的回报。
Generally speaking I would fragment my Mule configuration to have one service per fragment then load real service A fragment and a test service B fragment at test time. Test service B would use the Mule test:component to simulate good or bad returns.
