#safe_assert_block(*args, &block) ⇒ Object

Any subclass of Test::Unit::TestCase seems to automatically hook into the test suite. Therefore, calling a test to see if it returns false makes the suite fail. Including to this class instead prevents that.

I may need to more closely mimic Test::Unit::TestCase in order to test messages properly.
