Installation Testing
Most software systems have installation procedures that are needed before they can be used for their main purpose. Testing these procedures to achieve an installed software system that may be used is known as installation testing. These procedures may involve full or partial upgrades, and install/uninstall processes. Installation testing may look for errors that occur in the installation process that affect the user's perception and capability to use the installed software. There are many events that may affect the software installation and installation testing may test for proper installation whilst checking for a number of associated activities and events. Some examples include the following: * A user must select a variety of options. * Dependent files and libraries must be allocated, loaded or located. * Valid hardware configurations must be present. * Software systems may need connectivity to connect to other software systems. Installation testing may also be considered as an ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operational Acceptance Testing
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. OAT elaborates upon and compartmentalises operational aspects of acceptance testing. 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 vulnerabi ...

Software Testing
Software testing is the act of checking whether software satisfies expectations. Software testing can provide objective, independent information about the Quality (business), quality of software and the risk of its failure to a User (computing), user or sponsor. Software testing can determine the Correctness (computer science), correctness of software for specific Scenario (computing), scenarios but cannot determine correctness for all scenarios. It cannot find all software bug, bugs. Based on the criteria for measuring correctness from an test oracle, oracle, software testing employs principles and mechanisms that might recognize a problem. Examples of oracles include specifications, Design by Contract, contracts, comparable products, past versions of the same product, inferences about intended or expected purpose, user or customer expectations, relevant standards, and applicable laws. Software testing is often dynamic in nature; running the software to verify actual output ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Configuration Manager
Configuration management (CM) is a management process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. The CM process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings. Introduction CM applied over the life cycle of a system provides visibility and control of its performance, functional, and physical attributes. CM verifies that a system performs as intended, and is identified and documented in sufficient detail to support its projected life cycle. The CM proce ...

Software Deployment
Software deployment is all of the activities that make a software system available for use. Deployment can involve activities on the producer (software developer) side or on the consumer ( user) side or both. Deployment to consumers is a hard task because the target systems are diverse and unpredictable. Software as a service avoids these difficulties by deploying only to dedicated servers that are typically under the producer's control. Because every software system is unique, the precise processes or procedures within each activity can hardly be defined. Therefore, "deployment" should be interpreted as a ''general process'' that has to be customized according to specific requirements or characteristics. History When computers were extremely large, expensive, and bulky (mainframes and minicomputers), the software was often bundled together with the hardware by manufacturers. If business software needed to be installed on an existing computer, this might require an expens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
