How to set up Mockito for Kotlin and Android

Question

I want to use Mockito for unit testing, so I added the Mockito library into my gradle dependencies.

testImplementation 'junit:junit:4.12'
testCompile 'org.mockito:mockito-core:2.12.0' 

But still, I can not use any Mockito annotations.

/androidTest/ExampleTest.kt

@RunWith(MockitoJUnitRunner::class) // Unresolved reference MockitoJUnitRunner
@Mock // Unresolved reference Mock

What I'm missing it?

Answer 1

You need to add the following dependencies in your app's build.gradle:

dependencies {
    // ... more entries
    testCompile 'junit:junit:4.12'

    // required if you want to use Mockito for unit tests
    testImplementation 'org.mockito:mockito-core:2.24.5'
    // required if you want to use Mockito for Android tests
    androidTestImplementation 'org.mockito:mockito-android:2.24.5'
}
