How to unit test a ResponseBody or ResponseEntity sent by a spring mvc Controller?
提问by Nico
When I do junit tests, I do something like this to test spring mvc controllers :
当我做 junit 测试时，我会做这样的事情来测试 spring mvc 控制器：
request.setRequestURI("/projects/"+idProject+"/modify");
ModelAndView mv = handlerAdapter.handle(request, response, controller);
where controller tested is like :
控制器测试的地方是这样的：
@RequestMapping(value = "{id}/modify")
public String content(ModelMap model, @PathVariable("id") Project object) {
But I don't find how to get the ResponseBodyanswer of request handlers defined like this :
但我没有找到如何获得这样ResponseBody定义的请求处理程序的答案：
@RequestMapping("/management/search")
public @ResponseBody ArrayList<SearchData> search(@RequestParam("q")) {
....
....
ArrayList<SearchData> datas = ....;
return datas;
}

Your unit test only needs to verify the contents of the return value of the method:
你的单元测试只需要验证方法返回值的内容：
ArrayList<SearchData> results = controller.search("value");
assertThat(results, ...)
The @ResponseBodyannotation is irrelevant. This is one of the big benefits of annotated controllers - your unit tests can focus on the business logic, not the framework mechanics. With pre-annotation controllers, half of your test code is spent constructing mock requests, responses, and associated gubbins like that. It's a distraction.
该@ResponseBody注释是不相关的。这是带注释的控制器的一大好处 - 您的单元测试可以专注于业务逻辑，而不是框架机制。使用预注释控制器，您的测试代码的一半用于构建模拟请求、响应和类似的相关联的 gubbins。这是一种干扰。
Testing that your code's annotations integrate properly with the framework is the job of integration and/or functional tests.
测试您的代码的注释是否与框架正确集成是集成和/或功能测试的工作。
