Reading this article, I want the same now for js code that involves web-workers... How can I write code that involves a webworker in a way that I can simulate every possible CPU scheduling between the main thread in the webworker (given they communicate via post message and no shared array buffer)? Is it possible to write such brute force test in pure JS, without having to simulate the entire computer?
