Ability to hide some of the input/output test cases

Describe your feature request
I want to be able to choose if an input/output test that i created for a question in teams educational class, is a public test or a hidden test (the hidden ones are so students dont see the input/output of it, they just know if its right or wrong when they run it)

What problem(s) would this feature solve?
When students see all the possible inputs and outputs, they sometimes can skip the whole problem by just creating an “if else” structure that fits only those input/output test cases. And thats not the main idea of the exercise…

Explain what you were trying to do when you came across the problem leading to this feature request
When submiting an exercise on a Team. Its really annoying that you can bypass the whole algorithm that the question was inteended to create.
