Acceptance Testing Strategies (Part 2): Feature Tests, Pyramid, and Best Practices

In Part 1 we covered what acceptance tests are, plus inside-out and outside-in testing. Here we add the third strategy ( feature tests ) then compare all three, look at the testing pyramid, and share best practices for combining them. ← Part 1: Inside-Out and Outside-In 3. Feature Tests What are Feature Tests? Feature tests are comprehensive tests that validate complete features or user stories from end to end. They combine elements of both inside-out and outside-in testing to ensure features work correctly across all layers of the application. Think of feature tests as the "final exam" for a complete feature—they verify everything works together as expected. Characteristics Feature-focused : Tests complete features, not individual components Cross-layer : Spans multiple layers of the application Business-driven : Based on user stories and business requirements Integration-heavy : Tests how different components work together Example Implementation public class OrderManagementFeatureTes
