怎么在springboot中进行单元测试

 示例代码：

import static org.hamcrest.Matchers.equalTo;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringRunner.class)
@WebAppConfiguration
@SpringBootTest
public class DemoApplicationTests {

	private MockMvc mvc;

	@Before
	public void setUp() throws Exception{
		mvc = MockMvcBuilders.standaloneSetup(new HelloController()).build();
	}

	@Test
	public void contextLoads() throws Exception{
        mvc.perform(MockMvcRequestBuilders.get("/hello").accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk())
                .andExpect(content().string(equalTo("Hello")));
	}

}

 不要忘记上面的import 静态引用
