This is a simple project which shows an architecture used to run different types of tests

The project has three different modules

• /app - The Android application with instrumentation tests using Espresso and Spoon
• /core - A plain Java module which could allocate Java code such as HttpRequests, JSON parsers, etc. and runs JUnit tests
• /robolectric-tests - Robolectric tests for the /app module

Espresso tests can be run using:

./gradlew connectedCheck
./gradlew connectedAndroidTest

Spoon tests can be run using:

./gradlew spoon

JUnit and Robolectric tests can be ran using one of the following:

./gradlew test
./gradlew check
./gradlew build

JaCoCo reports can be generated for both /core and /robolectric-tests running:

./gradlew test jacoco
./gradlew check jacoco
./gradlew build jacoco
