Robustness Validation

Robustness Validation is a testing discipline that evaluates a system's ability to handle exceptional or unexpected conditions without crashing or failing. This includes verifying how the system responds to invalid data, resource limitations, or environmental disturbances to ensure it remains stable and resilient.

Example: A tester performs robustness validation on a new payment gateway by simulating a dropped network connection in the middle of a transaction. The test would then confirm that the system handles this failure gracefully by either successfully completing the transaction or correctly rolling back the changes to maintain data integrity, instead of freezing or crashing.
