Feature Testing: Complete Guide, Types & Best Practices

Every new feature a team ships is a bet. A bet it works, and solves the problem was built for, and doesn't quietly break something else in the process. Feature testing is how a team checks it bet before it goes live in front of real users. Unlike a full regression pass this re-checks an entire application, feature testing zooms in on one specific piece of functionality, whether a new checkout flow, a redesigned search bar, or a toggle that changes how recommendations get generated.
