Instrumented tests failure with AndroidJUnitRunner 1.0.0 and AssertJ

I’m trying to update my project to recently released Android Test Support library version 1.0.0. But if I add assertj-core dependency Gradle instrumented test tasks start to fail with “No tests found” message. I can successfully run individual tests from IDE though.

It is easy to reproduce the problem:

  • Android Gallery on Android 4.4 (KitKat) returns different URI for Intent.ACTION_GET_CONTENT
  • Android: Disable soft keyboard at all EditTexts
  • “Cannot override the final method from SherlockActivity”
  • how to set image from url for imageView
  • The GestureDetector does not work (example from android developer)
  • Register a device on GCM every time the app start is the right approach?
    1. Create new project from Android Studio 3 with empty activity.
    2. Add assertj-core dependency.
    3. Run instrumentation tests from command line ./gradlew connectedDebugAndroidTest.

    Gradle script.

    android {
        defaultConfig {
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
    }
    
    dependencies {
        implementation 'com.android.support:appcompat-v7:26.0.0'
        implementation 'com.android.support.constraint:constraint-layout:1.0.2'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'com.android.support.test:runner:1.0.0'
        androidTestImplementation group: "org.assertj", name: "assertj-core", version: "2.8.0"
    }
    

    Console output.

    com.android.builder.testing.ConnectedDevice > No tests found.
    [Nexus_4_API_25(AVD) - 7.1.1] FAILED 
    No tests found. This usually means that your test classes are not in the form that your test runner expects (e.g. don't inherit from TestCase or lack @Test annotations).
    

    Tests successfully run if downgrade com.android.support.test:runner to previous version 0.5.
