SFML/test/src/UnitTests.hpp
Jan Haller c3e5a35a6e Added string conversions for equality-comparable classes
Provides a Catch::toString() overload for the following SFML classes, that support at least operator== and operator!=, and can thus be used in Catch assertion expressions:
* String
* Time
* Vector2<T>
* Vector3<T>
* VideoMode
* Color
* Rect<T>

The intermediate header UnitTests.hpp is introduced to ensure string conversion visibility.
Do not include <catch.hpp> directly any longer.

// Header for SFML unit tests.
//
// For a new test case, include this header and not <catch.hpp> directly.
// This ensures that string conversions are visible and can be used by Catch for debug output.
