Spring MVC的单元测试

我自己写的例子：

 

public class PlayerControllerTest extends SpringWebTestCase {

	private MockMvc mockMvc;
	
	@Autowired
	private PlayerController controller;

	@Before
	public void setUp() {
		mockMvc = standaloneSetup(controller).build();
	}

	@Test
	public void testRegister() throws Exception {
		MockHttpServletRequestBuilder mock = post("/register");
		mock.contentType(MediaType.APPLICATION_FORM_URLENCODED)
			.param("loginId", "peak")
			.param("name", "gogogo")
			.param("password", "111")
			.param("mobile", "139")
			.param("email", "[email protected]");
		mockMvc.perform(mock)
			.andExpect(status().isOk())
			.andExpect(content().contentType("application/json;charset=UTF-8"))
			.andExpect(content().json("{\"success\":true,\"message\":\"操作成功\"}"))
			.andDo(print())
			.andReturn();
	}
}

为了简化静态引入，把父类里面加入了所有mock的方法进来，用的是Jackson
