User Acceptance Test ensures that the technical solution in bination with Business processes works as intended. This level of test can also be used for formal business acceptance. ? Operations Acceptance Testing bines the existing production system and operational instructions with the new solutions and its operational instructions. It ensures that nothing in the new release will degrade existing production performance and that all SLAs (Service Level Agreements) on the new solution can be met in the production environment. The following provides a more prehensive definition of the levels of test. Level Focus Benefit Unit (modules, enhancements, data migration) ? To test the function of a program or unit of code such as a program or module ? To test internal logic ? To verify internal design ? To test path amp。 UAT ? Test Schedules for each level of testing ? Test Objectives/Conditions Matrices ? Test Cases ? Test Results ? Test Defect and Test Management Reports Test Summary Reports TEST APPROACH The objective of test APS BR 1 will be to ensure the APS modules, operations and works that are in scope perform as specified in the business and technical documentation. FOCUS The overall objective of test is to reduce the risks inherent in systems. The process must address and minimize those risks. Thus, areas are identified to assist in drawing attention to the specific risks or issues where test effort is focused and which must be handled by the test strategy. It is virtually impossible and economically not feasible to perform exhaustive testing. The limited resources must be used optimally while reducing cycle time and costs. This means that only necessary and sufficient tests must be performed thus avoiding undertesting and overtesting. This leads to the key question: What are the factors, or risks that are most important to ? The user or the client? Overall Solution Architecture Huawei APS Project Page 13 of 29 ? The developer from a system perspective? ? The service provider? The answer lies in developing and selecting Test Focus areas that will address or minimize risks. Test Focus can be defined as those attributes of a system that must be tested in order to assure that the business and technical requirements can be met. The focus areas of testing will be on the following: Test Focus Area Description Priority Auditability Ability to provide supporting evidence to trace processing of data M Completeness Everything that is supposed to happen, does H Continuity of Processing Ability to continue processing if problems occur.
