import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@SpringBootTest
@AutoConfigureMockMvc
class SpringBootMqRocketmqApplicationTests {

    @Test
    public void testMQProducer(@Autowired MockMvc mockMvc) throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get("/sendMsg?msg=sendMSG")
                .accept(MediaType.APPLICATION_JSON))
                .andExpect(status().isOk())
                .andDo(print());
    }
