protected function BackdropUnitTestCase::setUp

Sets up unit test environment.

Unlike BackdropWebTestCase::setUp(), BackdropUnitTestCase::setUp() does not install modules because tests are performed without accessing the database. Any required files must be explicitly included by the child class setUp() method.
