При выполнении тестов Kotlin Unit и UI, 1 или 2 новых теста все время терпят неудачу

Question

Я пытаюсь запустить тестирование юнитов и пользовательского интерфейса в Котлине с использованием Junit и Espresso. Что действительно интересно, так это то, что каждый раз, когда я запускаю весь тест, 1 или 2 новых теста терпят неудачу. Кажется, в моих тестовых настройках есть систематический сбой. Что будет причиной этой проблемы? Любые предложения, где я должен начать отладку?

Настройка теста:

// Build.gradle
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.core:core-ktx:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation "androidx.recyclerview:recyclerview:1.0.0"
    implementation 'androidx.cardview:cardview:1.0.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'androidx.lifecycle:lifecycle-extensions:2.1.0'

    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-contrib:3.2.0'

    implementation 'com.google.code.gson:gson:2.8.5'
    implementation 'com.squareup.retrofit2:retrofit:2.6.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.6.0'
}

Несколько типов сообщений об ошибках, с которыми я сталкиваюсь в этой проблеме:
