Spring Boot Mvc 单元测试

1、开发 都是需要保存测试代码的，mvc也不例外，都需要写测试代码，下面写了一个简单的mvc 但愿测试的代码.

import org.junit.Test;
import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mock.web.MockHttpSession;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;

import static org.assertj.core.api.Assertions.assertThat;
