// Stupidly simple automated testing framework
// by ector
// licence: Public Domain
// If TESTING_ENABLE is true, all tests across the project will run before main().
// If it's false, all tests will be destroyed by the linker, hopefully.
// Unfortunately, MSVC:s library linker seems to kill off unreferenced objects, even if the
// initialization has side effects. This makes this framework not work properly :(
// TODO(ector): Find solution.
// TODO(ector): make sure tests are destroyed and that things compile without TESTING_ENABLE :P
