Testing is a key component for learning, regardless of the learning method.

“testing as a form of studying whether or not self-directed or given to you by a teacher is not for sake of evaluation at the level of okay you know you get an exam at the end of a lecture and then you do your best to answer those questions and then you turn it in and it impacts your grade no this is about being told or revealing to yourself how much you know and don't know and then of course being told the correct answers so that you can compare your answers to the correct answers”
