Service Validation and Testing defines the testing of services during the Service Transition phase. This will ensure that new or changed services are fit for purpose (this is known as utility) and fit for use (this is known as warranty).
Service Validation and Testing's goal is to make sure the delivery of activities adds value that is agreed and expected. If testing hasn't been carried out properly, additional Incidents and Problems will arise.
There are a number of activities for Service Validation and Testing, these include:
- Validation and Test management - This consists of planning and managing/controlling and then reporting on the activities that have taken place during all phases to ensure they are fit for purpose/use.
- Planning and Design - Test planning and design activities take place in the early stages of the Service Lifecycle. These correlate to resources, supporting services, scheduling milestones for delivery and acceptance.
- Verification of Test Plan and Design - Test plans and designs are validated to ensure all activities are complete (this also includes test scripts). Test models are also verified to minimise the risks to the service.
- Preparation of the Test environment - Prepare and make a baseline of the test environment.
- Testing - Tests are carried out using manual or automated testing techniques and procedures. All results are registered.
- Evaluate Exit Criteria and Report - Actual results are compared with projected results.
- Clean up and Closure - Ensure the test environment is cleaned. Learn from previous experiences and identify areas for improvement.
