Dynamic languages like Python do not have this issue as you can mock any method runtime for the duration of test. This can done via "monkey patching". It is unclean, but the development cost of having a framework to do just this is a tad high. The only downside is that if you parallel test you need to run them in separate processes (which you usually want to do.any case).
