What Is Sandbox Testing? Types, Benefits, And Best Practices (2026)
Sandbox testing catches the failures that staging misses, and production makes expensive. Every team reaches a point where testing against real systems stops being practical. The payment gateway costs money per call. The third-party notification service has rate limits. One wrong database query corrupts shared test data and breaks everyone’s runs. A sandbox environment for testing gives you an isolated, controlled space where none of that matters.
