Android Test Orchestrator

Using Orchestrator it’s great! Improves Android automation test runs. Orchestrator ensures that the app’s state is completely cleared between tests, helps solve flaky tests. Background.

Configuration: it’s pretty easy, just add below code to your build.gradle

android {..
   defaultConfig {..
// Espresso tests
 testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
// Cleared between tests.
testInstrumentationRunnerArguments clearPackageData: 'true'
testOptions {
              execution 'ANDROID_TEST_ORCHESTRATOR'
}}}
dependencies {
  androidTestImplementation 'com.android.support.test:runner:1.0.2'
  androidTestUtil 'com.android.support.test:orchestrator:1.0.2'
}

Clean project, and now using Android Studio run your Espresso tests using Orchestrator.
