lateinit property has not been initialized on some ancestor classes

[superdrenner]

Expected Behavior

Mockks should be injected in all superclasses and not just the top most parent

• MockK version: 1.13.9
• OS: Mac OS 13.6.3
• Kotlin version: 1.4.10
• JDK version: Corretto-11.0.21.9.1 (build 11.0.21+9-LTS)
• JUnit version: 5.7.0
• Type of test: Unit Test

kotlin.UninitializedPropertyAccessException: lateinit property convertApplicationService has not been initialized

Minimal reproducible code (the gist of this issue)

abstract class Grandparent {
    @Autowired
    private lateinit var serviceA: ServiceA
	
    open fun doSomething() {
        // serviceA has been injected correctly
        serviceA.doIt()
    }
}

abstract class Parent : Grandparent() {
    @Autowired
    lateinit var serviceB: ServiceB
  
    override fun doSometing() {
        super.doSomething()
  
        // Failure happens here, serviceB has not been initialized
        serviceB.doIt()
    }
}

class Child: Parent() {
    @Autowired
    lateinit var serviceC: ServiceC
 
    override fun doSomething() {
        super.doSomething()
        // serviceC has been injected correctly
        serviceC.doIt()
    }
}

@ExtendWith(MockkExtension::class)
class ChildTest {
    @Mockk
    private lateinit var serviceA: ServiceA

    @Mockk
    private lateinit var serviceB: ServiceB

    @Mockk
    private lateinit var serviceC: ServiceC

    @InjectMockks
    private lateinit var child: Child


    @Test
    fun theTest () {
       child.doSomething()
    }
}

Hi @drennerpfc6 , Did you use MockKAnnotations.init() in your test or not ?

[superdrenner]

@OmarBeshary the test class is using MockkExtension so MockkAnnotations.init() is not required.
