Writing tests that help evolve a system is hard, and you get there by avoiding smart tests while preferring dumb ones. The Paradox of Smart Tests Smart is always better than dumb, isn’t it? This time we’ll look at the paradox that dumb programmer tests are superior to smart ones. Let’s dive in.

James Shore, author of the book “The Art of Agile”, wrote an article that covers the alternatives to acceptance testing. The way you write an acceptance test is to take a user story and then write code that tests the end result of a software process. When it comes to testing, my goal is to eliminate defects.
