Answer 1

For anyone else struggling with the Cannot convert string value 'ANDROIDX_TEST_ORCHESTRATOR' to an enum value of type 'com.android.builder.model.TestOptions$Execution' (valid case insensitive values: HOST, ANDROID_TEST_ORCHESTRATOR) error message, ANDROIDX_TEST_ORCHESTRATOR seems to be incompatible with the latest version of IntelliJ (2018.3.5), it worked fine in Android Studio (3.3.2).

Anyone with Complex projects - here are my gradle changes

repositories {
mavenCentral()
flatDir {
    dirs 'aars'
}
maven {
    url "https://maven.google.com"
}
google()}

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

dependencies {
compile 'androidx.lifecycle:lifecycle-extensions:2.0.0'
compile 'androidx.core:core:1.0.0'
compile 'androidx.recyclerview:recyclerview:1.0.0'
compile 'androidx.appcompat:appcompat:1.0.0'
implementation 'androidx.multidex:multidex:2.0.0'
//kapt 'androidx.databinding:databinding-compiler:1.0.0'
androidTestImplementation('androidx.test:runner:1.1.0', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
androidTestImplementation('androidx.test:rules:1.1.0', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
androidTestUtil 'androidx.test:orchestrator:1.1.0'
implementation 'androidx.test.espresso:espresso-idling-resource:3.1.0'
// Espresso support
androidTestImplementation('androidx.test.espresso:espresso-core:3.1.0', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
androidTestImplementation('androidx.test.espresso:espresso-intents:3.1.0', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
androidTestImplementation('androidx.test.espresso:espresso-web:3.1.0', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile('androidx.room:room-runtime:2.0.0', {
    exclude group: 'com.android.support'
})
kapt 'androidx.room:room-compiler:2.0.0'
compile('androidx.room:room-rxjava2:2.0.0', {
    exclude group: 'com.android.support'
})
testCompile('androidx.room:room-testing:2.0.0', {
    exclude group: 'com.google.code.gson'
})
androidTestImplementation('androidx.test.espresso:espresso-contrib:3.1.0') {
    exclude group: 'com.android.support', module: 'appcompat'
    exclude group: 'com.android.support', module: 'support-v4'
    exclude module: 'recyclerview-v7'
}
compile 'androidx.exifinterface:exifinterface:1.0.0'}

       classpath 'com.android.tools.build:gradle:3.4.1'

rest of the errors I had to fix manually but in the end it worked

Answer 3

Purely by guessing, I changed the following in my gradle config

from:

  testOptions {
    execution 'ANDROID_TEST_ORCHESTRATOR'
  }

to

  testOptions {
    execution 'ANDROIDX_TEST_ORCHESTRATOR'
  }

and all seems to work.
