// QUnit.hpp - a simple unit test framework for C++
//
// Original: svn r26
// Updated to coloured printing by Harry van Haaren <harryhaaren@gmail.com>
//
// Typical usage:
//
// #include "QUnit.hpp"
//
// int main() {
// QUnit::UnitTest qunit(std::cerr, QUnit::verbose);
//
// QUNIT_IS_TRUE(true);
// QUNIT_IS_FALSE(4!=4);
// QUNIT_IS_EQUAL(42, 42.0);
// QUNIT_IS_NOT_EQUAL(42,"43");
//
// return qunit.errors();
// }
