API Testing Over UI Testing

Your UI tests are breaking every sprint, but your APIs haven't changed.The problem? You're testing through the most unstable layer of your application.Pro tip: Test business logic through APIs first, then add UI tests only for user journeys that can't be validated any other way.APIs are:✅ 10x faster to execute✅ More reliable and stable✅ Easier to debug when they fail✅ Perfect for testing edge casesSave UI tests for what actually matters: user experience validation.
