Overview

Tests for the SuccessResult class.

This suite verifies that the SuccessResult singleton behaves as expected:

  • It is a singleton (all calls to SuccessResult.instance return the same object)

  • The #success? method returns true and #failure? returns false

  • The default message and string representation are correct.
