Using Spek with UI tests on Android

rgal75 commented 3 years ago

I am trying to use Spek 2 for UI testing on Android but I always get an ExceptionInInitializerError when trying to launch an Activity with ActivityScenario.launch(...):

java.lang.ExceptionInInitializerError
    at androidx.test.core.app.ActivityScenario.launch(ActivityScenario.java:194)

My dependencies are:

dependencies {
    def spek_version = "2.0.15"
    def fragment_version = "1.3.0-rc01"

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.3.2'
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.2.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    implementation 'androidx.navigation:navigation-fragment:2.3.2'
    implementation 'androidx.navigation:navigation-ui:2.3.2'
    implementation 'androidx.lifecycle:lifecycle-livedata-ktx:2.2.0'
    implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0'
    implementation 'androidx.navigation:navigation-fragment-ktx:2.3.2'
    implementation 'androidx.navigation:navigation-ui-ktx:2.3.2'

    testImplementation "org.jetbrains.kotlin:kotlin-test:$kotlin_version"
    testImplementation "com.nhaarman.mockitokotlin2:mockito-kotlin:2.2.0"
    testImplementation "org.spekframework.spek2:spek-dsl-jvm:$spek_version"
    testImplementation "org.spekframework.spek2:spek-runner-junit5:$spek_version"
    // spek requires kotlin-reflect, omit when already in classpath
    testImplementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
    testImplementation "com.google.truth:truth:1.1"

    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
    androidTestImplementation 'androidx.test:runner:1.1.0'
    androidTestImplementation 'androidx.test:rules:1.1.0'
    androidTestImplementation "org.spekframework.spek2:spek-dsl-jvm:$spek_version"
    androidTestImplementation "org.spekframework.spek2:spek-runner-junit5:$spek_version"
    androidTestImplementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"

    debugImplementation "androidx.fragment:fragment-testing:$fragment_version"
}

My spec:

object DiaryFragmentSpec: Spek({

    describe("DiaryFragment") {
        beforeEachTest {
            ActivityScenario.launch(MainActivity::class.java)
        }
        it("shows the text `This is Diary Fragment`") {
            onView(withId(R.id.text_diary)).check(matches(withText("This is Diary Fragment")))
        }
    }
})

Is there a sample project that shows how to use Spek 2 with instrumented testing on Android?

Sorry for the delay! I'm not sure if it is totally possible at the moment, do mind I'm no android dev. Have you tried looking at https://github.com/mannodermaus/android-junit5? The instrumentation test part of the doc looks interesting. Spek provides a JUnit Platform engine (spek-runner-junit5) which might work with it.

Thanks, I will look into https://github.com/mannodermaus/android-junit5.
