Do stock picker strategies need robustness tests?

Hi, I’m learning stock picker strategies these days, and I’m going to try on AlgoCloud. However, I found there’re no lesson about ROBUSTNESS TESTS in your courses, such as MC or WFM. Doesn’t the stock picker strategies need them? What if they’re no profitable?

We plan to include the tests in StrategyQuantX. It’s always good to run at least the most basic robustness tests before deploying the strategy. Stockpicking strategies are no exception
