Question

嗨，我有一个名为UserServiceTest的测试类，其中包含与上述模拟一起注入的userService类，并且该测试类中的测试正常运行。

@RunWith(MockitoJUnitRunner::class)
class UserServiceTest {

lateinit var login: Login

@Mock
lateinit var userRepository: UserRepository

@Mock
lateinit var emailService: EmailService

@InjectMocks
lateinit var userService: UserService

@Before
fun setup() {
    login = Login(email = "mohanraj@gmail.com", password = "qwerty"
}

我还有另一个名为AdminServiceTests的测试类，其中包含AdminServiceClass，该类与上述模拟一起注入，其中也包含userService类

@RunWith(MockitoJUnitRunner::class)
class AdminServiceTests {

lateinit var user: User

@Mock
lateinit var userRepository: UserRepository

@Mock
lateinit var adminRepository: AdminRepository

@Mock
lateinit var userService: UserService

@InjectMocks
lateinit var adminService: AdminService

@Before
fun setup() {

    this.createAdmin = CreateAdmin().apply {
        email = "admin@gmail.com"
        name = "admin"
        password = "qwerty"
        phone = 98345678899
    }
}

@Test
fun testCreateAdmin() {

    val result = adminService.createAdmin(createAdmin)
    Assert.assertEquals(true, result)
}

运行测试时，adminService.createAdmin（createAdmin）在adminService中调用一个函数，在adminService中调用一个函数

fun createAdmin(newUser: CreateAdmin): Boolean {
    val user = userService.getUser(newUser)

    if (userService.createUser(user)) { // calls a function in user service
        this.saveAdmin(user.id)

        return true
    }

    return false
}

我想从testCreateAdmin函数中调用userService中的一个函数，但是我作为@Mock包含的用户服务本身包含一些依赖关系，并且它是adminService的依赖关系，因此当我调试@Mock userService对象时，其包含null因此，不会调用userService中的函数。那么如何将依赖项注入到userService并将其注入到adminService中。请帮助

userService = {UserService$MockitoMock$825690330@2479}
mockitoInterceptor = {MockMethodInterceptor@2532} 
userRepository = null
emailService = null

在您的testCreateAdmin()中，您必须模拟userService方法的行为。默认情况下，非模拟方法将返回null。

它应该是这样的，带有mockito-kotlin。

@Test
fun testCreateAdmin() {
  val admin = mock<User>() {
    on { id } doReturn "id"
  }
  whenever(userService.getUser(createAdmin)).doReturn(admin)
  whenever(userService.createUser(admin)).doReturn(true)

  val result = adminService.createAdmin(createAdmin)

  Assert.assertEquals(true, result)
  verify(userService).saveAdmin("id")
}

从测试类调用函数不起作用Mockito
