info Android Continous Integration

Continuous Integration

Goal is that every time you commit your code, your code automatically goes thru some Junit testing (iOS/Android) and also builds the apps (ipa/apk). CI helps improves the quality of the app. Ideally is nice to have one system when you can kick a build and also run your unit and integration tests. CI is key to have a great app :)

Circleci:
Proof of Concept - Android Continuous Integration with gradlew and Circleci

Circleci uses the build file: circle.yml, you need to create and add this file to your project root.
Circleci builds apk and runs Espresso UI test(click button change text).
