spring boot项目的测试用例怎么写?

官网有例子

@RunWith(SpringRunner.class)
@DelegateTo(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = {TestApplication.class }, properties = {"a = 1", "b = 2"})
public class SBTest {

protected Logger logger = LoggerFactory.getLogger(this.getClass());

private WebApplicationContext wac;

private MockMvc mvc;
private MockHttpSession session;

@Before
public void setupMockMvc(){
    mvc = MockMvcBuilders.webAppContextSetup(wac).build();
    session = new MockHttpSession();
}

@Test
public void test1() throws Exception{
    String responseString = mvc.perform(MockMvcRequestBuilders.post("/a/b")
                                            .accept(MediaType.APPLICATION_JSON_UTF8)
                                            .param("c","d")
                                            .session(session)
    )
        .andExpect(MockMvcResultMatchers.status().isOk())
        .andReturn().getResponse().getContentAsString();
    logger.warn(responseString);
}

}

其中: TestApplication 是包含你 spring boot项目的配置文件
@SpringBootApplication(scanBasePackages = "com.xxxx")
@PropertySource("classpath:test.properties")
@ImportResource({ "classpath*:import.xml" })
public class TestApplication {
}
