Service Validation and Testing has been introduced as a new process in ITIL. Major additions are details on the various testing stages during Service Transition and descriptions of commonly used testing approaches.
Test Model Definition
To specify in detail how the Release will be tested and quality-assured. In particular, this process defines the testing concept and specific test cases to be used during Service Validation.
Release Component Acquisition
To acquire the components of a Release and submit them to an initial assessment. This process ensures that only components which meet stringent quality criteria are allowed to enter the intensive testing phase.
To test all Release Components and all tools and mechanisms required for deployment, migration and back out. This process ensures that only components which meet stringent quality criteria are deployed into the live productive environment.
Service Acceptance Testing
To verify if all conditions are met for the new service to be activated, and to obtain a binding consent from the customer that the new service fulfills the agreed Service Level Requirements.
