词条 | Operational acceptance testing |
释义 |
Operational acceptance testing (OAT) is used to conduct operational readiness (pre-release) of a product, service, or system as part of a quality management system. OAT is a common type of non-functional software testing, used mainly in software development and software maintenance projects. This type of testing focuses on the operational readiness of the system to be supported, and/or to become part of the production environment. Hence, it is also known as operational readiness testing (ORT) or operations readiness and assurance testing (OR&A). Functional testing within OAT is limited to those tests which are required to verify the non-functional aspects of the system. According to the International Software Testing Qualifications Board (ISTQB), OAT may include checking the backup/restore facilities, IT disaster recovery procedures, maintenance tasks and periodic check of security vulnerabilities.,[1] and whitepapers on ISO 29119 and Operational Acceptance by Anthony Woods,[2] and ISO 25000 and Operational Acceptance Testing by Dirk Dach et al., OAT generally includes:[3]
During OAT changes may be made to environmental parameters which the application uses to run smoothly. For example, with Microsoft Windows applications with a mixed or hybrid architecture, this may include: Windows services, configuration files, web services, XML files, COM+ components, web services, IIS, stored procedures in databases, etc. Typically OAT should occur after each main phase of the development life cycle: design, build, and functional testing. In sequential projects it is often viewed as a final verification before a system is released; where in agile and iterative projects, a more frequent execution of OAT occurs providing stakeholders with assurance of continued stability of the system and its operating environment. An approach used in OAT may follow these steps:
For running the OAT test cases, the tester normally has exclusive access to the system or environment. This means that a single tester would be executing the test cases at a single point of time. For OAT the exact Operational Readiness quality gates are defined: both entry and exit gates. The primary emphasis of OAT should be on the operational stability, portability and reliability of the system.
