You were quoting me trying to say that mocking out system interactions, such as I /O, things with external side-effects, tends to be harder, regardless of Python versus Java. > Mocking is actually pretty easy to do in python Let's disagree. As a Java developer, doing some Python takes me a moderate amount of online searching, unless I'm writing the test code, during which the online searching and associated trial and error skyrockets. Just my modest experience.
