@parameter backtrace [Array] The backtrace to display.
@parameter message [String] The message to display.
@parameter orientation [Boolean] The orientation of the assertions.
@parameter condition [Boolean] The result of the test.

Otherwise, it is a failed outcome.
If the orientation is false, and the test failed, then it is a successful outcome.
If the orientation is true, and the test passed, then it is a successful outcome.
