Hey everyone should it be

android {
    defaultConfig {
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
}

or

android {
    defaultConfig {
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner4"
    }
}

or

android {
    defaultConfig {
        testInstrumentationRunner "androidx.test.ext.junit.runners.AndroidJUnit"
    }
}

???

Mine is:

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

OK cause all 4 seem to work 🙂 thanks
