Truth is a testing framework designed to make your tests and their error messages more readable and discoverable, while being extensible to new types of objects.

Truth adopts a fluent style for test propositions, is extensible in several ways, supports IDE completion/discovery of available propositions, and supports different responses to un-true propositions. Truth can be used to declare JUnit-style assumptions (which skip the test on failure), assertions (interrupt the test on failure), and expectations (continue the test, but collect errors and report failure at the end).

Fun to use Floating Action Button (FAB) view for Android 4.0 and higher.
