I think what dep_b refers to is that, in dynamic languages, you usually have an easier time injecting mocks and doubles. In a staticly typed language, it's usually much harder to inject mocks for IO, network, clock, etc., unless the original code has already been written to afford that (e.g. that whole Dependency Injection mess in Java).

That's exactly what I meant, thanks
