This library provides a JUnit TestRule that plants a temporary Timber tree that pipes any logs sent via Timber to the standard System.out. Once a unit test has completed, the Timber tree is removed to avoid logging unintended test cases.

There are many ways to modify the output using the following behaviours:

• The minimum log level to output.
• Whether thread ids are shown.
• Whether timestamps are shown.
• Whether to always log, or only log when a unit test fails.
