I gave a presentation called Testable Software Architecture [1] a week ago with very similar recommendations to this article.

Decoupling is essential in order to have fast, maintainable tests that give you confidence to deploy continuously.

My two favourite techniques for this is a ports&adapters architecture where we plug in fake adapters for the majority of the tests. We then use contract tests to be confident that the fakes behave the same as the real services.
