如何使用MockMvc测试下面的函数？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

@RunWith(SpringRunner.class)
@WebMvcTest(UserController.class)
public class UserControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testGetUser() throws Exception {
        // 发送GET请求并断言返回状态码为200
        mockMvc.perform(MockMvcRequestBuilders.get("/users/{id}", 1))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.jsonPath("$.id").value(1))
                .andExpect(MockMvcResultMatchers.jsonPath("$.name").value("John Doe"));
    }

    @Test
    public void testCreateUser() throws Exception {
        // 发送POST请求并断言返回状态码为201
        mockMvc.perform(MockMvcRequestBuilders.post("/users")
                .contentType(MediaType.APPLICATION_JSON)
                .content("{\"name\":\"Jane Smith\"}"))
                .andExpect(MockMvcResultMatchers.status().isCreated());
    }
}
