As we have seen in Chapter 9, Unit and Functional Tests, unit testing is performed with minimal connection to the system infrastructure and tests the different components in isolation. We will see different tools that allow us to easily perform unit tests on Android applications. They are as follows:
Spoon
Mockito
Android Mock
FEST Android
Robolectric

For a device to be considered by Spoon to run tests on, it has to be visible to the Android Debug Bridge (adb) devices. You can even perform the tests on different types of devices at the same time, such...
