Why is end-to-end testing important for modern applications?
Modern applications rely on multiple services, APIs, databases, and third-party integrations working together smoothly. Even if individual components work correctly, users can still face issues when complete workflows fail. This is why end-to-end testing is critical for validating real user journeys from start to finish. It helps teams detect workflow failures, improve release confidence, reduce production bugs, and ensure better user experience across the application.
