@retry(Exception, tries=3, timeout_secs=0.1)
def test_retry_via_decorator():
    throw_err('retry-via-deco')


def test_retry_via_instance():
    cbe = {
        Exception: lambda: callback('retry-via-instance')
    }
    retry(tries=3, callback_by_exception=cbe)(throw_err)('retry-via-instance')


def test_retry_via_instance2():
    cbe = {
        Exception: lambda: callback('retry-via-instance2')
    }
    RetryHandler(tries=3, callback_by_exception=cbe)(throw_err, 'retry-via-instance2')
