Elegant programming - MockMvc

MockMvc realized simulation Http request can be directly used in the form of a network, switch to invoke the Controller so that the test speed can not rely on the network environment, but also provides a means of verification, so that the request may validate the tax and very convenient, the most convenient for customers to test, start the server does not need to test our Rest Api.

SpringMVC example written Rest

Controller Example

@Controller
@RequestMapping(value = "/test")
public class TestWebController {

    @ResponseBody
    @RequestMapping(value = "/list", method = {RequestMethod.GET})
    public List getMock(@RequestParam(name = "id", required = false, defaultValue = "l0") String id) {
        return Arrays.asList("l1", "l2", "l3", id);
    }

    @ResponseBody
    @RequestMapping(value = "/pust", method = {RequestMethod.POST})
    public Object postMock(@RequestBody Object data) {
        return ImmutableMap.<String, String>builder().put("data", JSON.toJSONString(data)).build();
    }
	
	 @RequestMapping(value = "/view", method = {RequestMethod.GET})
    public ModelAndView viewMock(){
        return new ModelAndView("index");
    }

MockMvc can be simulated in one call controller; 1, mockMvc.perform execution request; 2, MockMvcRequestBuilders.get (urlTemplate, urlMultiParams) a request for configuration 3, ResultActions.andExpect assertion added after completion of execution of 4, ResultActions.andDo added a processor result, said to do something with the results, such as used here MockMvcResultHandlers.print () result information in response to the output of the whole. 5, ResultActions.andReturn represents return the results after the execution is completed.

Results of the:

["l1","l2","l3","l0"]
