Stress from tests depends more on what you test instead of how much. Of course if you just see it as an assessment tool instead of a teaching tool it can become a problem, but one of the best way to teach people is to test them before teaching. In a classroom this could be done by asking the kids to write down their answers, then you discuss the answers in class, then you give your answer and then you discuss that. The important part is to teach kids that they can think on their own and often come to reasonable conclusions without any help at all. And even when they fail they now understand better the difference between their wrong answer and a correct answer.
