Very nice.

What is the trade-off between the two? Does it make the tests significantly slower to test the entire stack rather than just a handler?

I usually do both. I like having unit tests that test individual function that describe functionality. But I also like to have tests that ensure everything works as intended ones you throw everything together.

To be clear, you test individual functions handler uses, and to test the handlers themselves, you opt to test the whole stack as described in the article?

Not part of the post but can't help and laugh at the company's marketing snipped below. Buzz-worthy!
