unit-testing - 由于 mockito，Android 仪器测试失败

问题描述

嗨，我收到以下错误


org.koin.error.BeanInstanceCreationException: Can't create definition for 'Single [name='NetworkControllerContract',class='com.network.contract.NetworkControllerContract']' due to error :

Mockito cannot mock this class: class com.network.NetworkController.

我已经手动打开了这些课程..

open class NetworkController constructor(private val networkHelper: NetworkHelperContract) : NetworkControllerContract{.....}

open interface NetworkControllerContract {
}

//my test class

@RunWith(AndroidJUnit4::class)
class MyUnitTest: KoinTest {

   single<NetworkControllerContract> {
            Mockito.mock(NetworkController::class.java) //where it crashes
        }

   val networkController: NetworkControllerContract by inject()

}

我使用的依赖项


   def mockito = "2.21.0"

//android instrumental test
    androidTestImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
    androidTestImplementation 'androidx.test.ext:junit:1.1.0'

    androidTestImplementation('androidx.arch.core:core-testing:2.0.0') {

    }

    }

    }

解决方案

问题出在您的设置中：

testImplementation "org.mockito:mockito-android:$mockito"

此依赖项使用 Android 内部，在运行单元测试时不可用。
