It took a lot of time to execute this intent test. (mainly dependency problems ??)

@Test
public void onActivityResultTest() {

    //
    // CHECK:
    //  The physical device is NOT locked.
    //

    // Is this always zero ?
    onView(withId(R.id.display_high_score)).check(matches(withText("max combo: 0")));

    // The activity is mocked
    Intent resultData = new Intent();
    resultData.putExtra(MainActivity.INTENT_KEY_MAX_COMBO, 123);
    android.app.Instrumentation.ActivityResult result =
            new android.app.Instrumentation.ActivityResult(Activity.RESULT_OK, resultData);
    intending(toPackage("io.kokoichi.sample.rhythmgame")).respondWith(result);

    // Click the start button
    onView(withId(R.id.play)).perform(click());

    // Check whether other activity is called.
    intended(toPackage("io.kokoichi.sample.rhythmgame"));

    // Check whether the max_combo is updated according to the ACTIVITY RESULT or not.
    onView(withId(R.id.display_high_score)).check(matches(withText("max combo: 123")));
}

This is the dependencies in build.gradle

dependencies {

    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.0'

    testImplementation 'junit:junit:4.+'
