/// We require coroutine support to be able to run C++ with flutter
/// as we need to suspend the tests and run the flutter event loop
/// to process events. For this reason we can't use doctest, as it doesn't
/// support coroutines and has several internal functions that don't return awaitables.
/// We're now using a custom "testing framework" until finding something better.
/// For now it just has the minimum required to run tests
