Frequent recall and testing is for many subjects the most effective teaching methodology.
If you have to get rid of lectures, books, workshops, projects, or informal testing; then testing should be the last thing to go.
This is not merely my opinion, it is one of the most reliable results in pedagogical research.

Calcifying the most important teaching methodology with this type of privacy invasive crap is harmful to the pedagogical process.

Students with self-motivation issues benefit most from frequent informal testing that covers small chunks of material.
Formality and privacy invasion only heighten the perfectionism and anxiety issues that constitute much of procrastinating behavior.

Formalized testing most often occurs at the end of semesters, when there is no time left for course correction by teachers or students anyway.

Informal testing can easily fulfill the role of gauging material absorption, and students cheating is then simply at their own peril.
When testing is informal, teachers can just use easy to cheat multiple choice tests, and not waste so much time with grading either.

But in any case, responsibility for ensuring that material is sufficiently understood should be held by students themselves.

It is only formalized exams and accreditation that could require measures to deal with cheating.
But such exams serve no direct function in education, and are entirely about the role of schools and universities under capitalism.
