What is Truth?

Truth makes your test assertions and failure messages more readable. Similar to AssertJ, it natively supports many JDK and Guava types, and it is extensible to others.

Truth is owned and maintained by the Guava team. It is used in the majority of the tests in Google’s own codebase.
