Mockito 2 pour Android Test d'instrumentation: impossible d'initialiser le plugin: interface org.mockito.plugins.MockMaker

J'utilise Mockito 2 et Espresso pour les tests unitaires et j'ai rencontré un problème en essayant d'utiliser Mockito 2 dans le test d'instrumentation. Pendant l'exécution du test, je reçois cette erreur

Et voici le code de test.

 @Test
fun testUserResultReturnsEmpty() {

    val userMock = Mockito.mock(UserModel::class.Java)
    Mockito.`when`(ArmOpApplication.getUserFromPrefs()).thenReturn(userMock)

    mActivityRule.launchActivity(Intent())
    mCountDownLatch.await(3000, TimeUnit.MILLISECONDS)

    assertNotNull(mActivityRule.activity.mInsightCategories)

    assertNull(mActivityRule.activity.mData)
    assertNull(mActivityRule.activity.insightsRecyclerView.adapter)
}

J'ai cherché sur Google pour plus d'informations et j'ai découvert que je devais utiliser mockito-Android au lieu de mockito core, et j'ai ajouté ces lignes dans le fichier build.gradle de l'application

androidTestImplementation "org.mockito:mockito-Android:${libMockitoAndroidVersion}"
androidTestImplementation 'com.linkedin.dexmaker:dexmaker-mockito:2.2.0'

where libMockitoAndroidVersion = 2.16.0

J'ai également ajouté le fichier org.mockito.plugins.MockMaker dans le répertoire de ressources androidTest pour travailler avec les classes de Kotlin.

enter image description here

Existe-t-il un moyen de résoudre ce problème? Toute aide serait appréciée.

À partir de la trace de la pile, il semble que vous utilisez le créateur de maquette en ligne Byte Buddy qui ne fonctionne pas sur Android. Assurez-vous que vous ne l'avez pas inclus de manière transitoire, car les deux plugins disponibles chargeraient d'abord celui qui est ajouté au chemin de classe.

Travailler avec Android replace

androidTestImplementation "org.mockito:mockito-core:$mockito_core_version"
androidTestImplementation "org.mockito:mockito-inline:$mockito_core_version"

for

androidTestImplementation "org.mockito:mockito-Android:$mockito_core_version"

Ma version était: $mockito_core_version = '2.28.2'

Cela m'a aidé

androidTestImplementation("org.koin:koin-test:1.0.2")
{ exclude("org.mockito", "mockito-inline") }
androidTestImplementation("org.mockito:mockito-Android:2.24.5")

Koin représente une bibliothèque contenant org.mockito

J'ai un problème similaire. I mon cas qui était une déclaration invalide en resource/mockito-extensions/org.mockito.plugins.MockMaker fichier. Au cours d'un processus de refactoring IDE a remplacé la valeur correcte:

mock-maker-inline

avec celui-ci:

infrastructure-maker-inline

J'ai remarqué ce changement accidentel lors de l'examen de la différence de validation, car elle ne semblait pas suspecte à première vue.
