41、ope perform as specified in the business and technical documentation.FocusThe 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

42、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 perfo

43、rmed thus avoiding under-testing and over-testing. This leads to the key question: What are the factors, or risks that are most important to The user or the client? The developer from a system perspective? The service provider?The answer lies in developing and selecting Test Focus areas that will ad

44、dress 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 AreaDescriptionPriorityAuditabilityAbility to provide supp
