ELI5: Do doctors from developing countries (trained in developing countries) who come to American/European countries to practice medicine have to undertake additional tests?

American/European medical schools are some of the best in the world and some of the most rigorous, on the other hand standards of education in Africa/some Asian countries I imagine are lower. So would African/Asian doctors have to undertake additional tests to prove their skills?

Yes. Some are never allowed to practice medicine in their new country at all. Depending on where they're from, their options range from simply demonstrating training in an equivalent system to taking the basic licensing tests that all physicians have to pass to redoing a (multi-year) residency. If their degree isn't recognized at all, they're SOL.
