在使用springboot框架開(kāi)發(fā)接口時(shí)，都免不了寫(xiě)接口單元測(cè)試。

1.controller單元測(cè)試（業(yè)務(wù)類(lèi)參與）
2.controller單元測(cè)試（業(yè)務(wù)類(lèi)mock）

導(dǎo)入依賴(lài)包：

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

單元測(cè)試代碼：

@RunWith(SpringRunner.class)
@SpringBootTest
@FixMethodOrder(MethodSorters.NAME_ASCENDING)
@AutoConfigureMockMvc
public class UserControllerTest_bak {

    @Autowired
    MockMvc mockMvc;

    final String ID = "test_user";

    /**
     * 如果業(yè)務(wù)類(lèi)沒(méi)有開(kāi)發(fā)好,但是要做接口測(cè)試時(shí)
     * @MockBean
     * UserService userService
