It's unfortunate that the author used the word "testing" because I think the underlying point is correct: By the time you've compiled Rust, there's been a significant number of automated checks against your code, which less true of a language like Python. It's also unfortunate the author describes features of static typing as "unit tests" when there's already confusion over the term. I think it works as an analogy, but I think this is a place where not being clear it's an analogy invites confusion.
