What is Operational Testing?
Operational acceptance testing (OAT), a testing technique performed to verify the operational readiness (pre-release) of a product or application under test as part of Software test life cycle. This testing technique mainly focusses on operational readiness of the system, which is supposed to mimic the production environment.
Types of Operational Acceptance Testing:
Operational Documentation Review
End-to-End Test Environment Operational Testing
Service Level Agreement Monitoring Test
Load & Performance Test Operation
Backup and Restore Testing
Fail over Testing
OAT Testing Approach:
Build the system to mimic Prod Environment
Deploy the build
Supportability of the system
Backup/Recovery procedure Validation
