Test Automation
In software testing, test automation is the use of software separate from the software being tested to control the execution of tests and the comparison of actual outcomes with predicted outcomes. Test automation can automate some repetitive but necessary tasks in a formalized testing process already in place, or perform additional testing that would be difficult to do manually. Test automation is critical for continuous delivery and continuous testing. General approaches There are many approaches to test automation, however below are the general approaches used widely: * Graphical user interface testing. A testing framework that generates Graphical user interface, user interface events such as keystrokes and mouse clicks, and observes the changes that result in the user interface, to validate that the observable behavior of the program is correct. * API testing, API driven testing. A testing framework that uses a programming interface to the application to validate the behavio ...

Integration Testing
Integration testing is a form of software testing in which multiple software components, modules, or services are tested together to verify they work as expected when combined. The focus is on testing the interactions and data exchange between integrated parts, rather than testing components in isolation. Integration testing describes tests that are run at the integration-level to contrast testing at the unit or system level. Often, integration testing is conducted to evaluate the compliance of a component with functional requirements. In a structured development process, integration testing takes as its input modules that have been unit tested, groups them in larger aggregates, applies tests defined in an integration test plan, and delivers as output test results as a step leading to system testing. Approach Some different types of integration testing are big-bang, mixed (sandwich), risky-hardest, top-down, and bottom-up. Other Integration PatternsBinder, Robert V.: '' ...

Line Of Business
Line of business (LOB) is a general term which refers to a product or a set of related products that serve a particular customer transaction or business need. In some industry sectors, like insurance, "line of business" also has a regulatory and accounting definition to meet a statutory set of insurance policies. It may or may not be a strategically relevant business unit. "Line of business" often refers to an internal corporate business unit, whereas the term "industry" refers to an external view that includes all competitors competing in a similar market. A line of business will often examine its position within an industry using a Porter five forces analysis (or other industry-analysis method) and other relevant industry information. Computer applications In the context of computing, a "line-of-business application" is one of the set of critical computer applications perceived as vital to running an enterprise. For example: "Governance has become the hot topic in SOA ov ...

Information Technology Operations
Data center management is the collection of tasks performed by those responsible for managing ongoing operation of a data center. This includes ''Business service management'' and planning for the future. Historically, "data center management" was seen as something performed by employees, with the help of tools collectively called #Data center infrastructure management, data center-infrastructure management (DCIM) tools. Both for in-house operation and outsourcing, service-level agreements must be managed to ensure data-availability. Competition Data center management is a growing major topic for a growing list of large companies who both compete and cooperate, including: Dell, Google, HP Inc., HP, IBM, Intel and Yahoo!, Yahoo. Hardware/software vendors who are willing to live with coopetition are working on projects such as "The Distributed Management Task Force" (DMTF) with a goal of learning to "more effectively manage mixed Linux, Microsoft Windows, Windows and cloud envir ...

Test Environment
In software deployment, an environment or tier is a computer system or set of systems in which a computer program or software component is deployed and executed. In simple cases, such as developing and immediately executing a program on the same machine, there may be a single environment, but in industrial use, the ''development'' environment (where changes are originally made) and ''production'' environment (what end users use) are separated, often with several stages in between. This structured release management process allows phased deployment (rollout), testing, and rollback in case of problems. Environments may vary significantly in size: the development environment is typically an individual developer's workstation, while the production environment may be a network of many geographically distributed machines in data centers, or virtual machines in cloud computing. Code, data, and configuration may be deployed in parallel, and need not connect to the corresponding tier—for ...

Version Control
Version control (also known as revision control, source control, and source code management) is the software engineering practice of controlling, organizing, and tracking different versions in history of computer files; primarily source code text files, but generally any type of file. Version control is a component of software configuration management. A ''version control system'' is a software tool that automates version control. Alternatively, version control is embedded as a feature of some systems such as word processors, spreadsheets, collaborative groupware, web docs, and content management systems, e.g., Help:Page history, Wikipedia's page history. Version control includes viewing old versions and enables Reversion (software development), reverting a file to a previous version. Overview As teams develop software, it is common to Software deployment, deploy multiple versions of the same software, and for different developers to work on one or more different versions ...

Continuous Delivery
Continuous delivery (CD) is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software with greater speed and frequency. The approach helps reduce the cost, time, and risk of delivering changes by allowing for more incremental updates to applications in production. A straightforward and repeatable deployment process is important for continuous delivery. Principles According to Neal Ford, continuous delivery adopts "Bring the pain forward," tackling tough tasks early, fostering automation and swift issue detection. Continuous delivery treats the commonplace notion of a ''deployment pipeline'' as a lean Poka-Yoke: a set of validations through which a piece of software must pass on its way to release. Code is compiled if necessary and then packaged by a build server every time a change is committed to a source control repository, then teste ...

Continuous Integration
Continuous integration (CI) is the practice of integrating source code changes frequently and ensuring that the integrated codebase is in a workable state. Typically, developers Merge (version control), merge changes to an Branching (revision control), integration branch, and an automated system Software build, builds and software testing, tests the software system. Often, the automated process runs on each Commit (version control), commit or runs on a schedule such as once a day. Grady Booch first proposed the term CI in Booch method, 1991, although he did not advocate integrating multiple times a day, but later, CI came to include that aspect. History The earliest known work (1989) on continuous integration was the Infuse environment developed by G. E. Kaiser, D. E. Perry, and W. M. Schell. In 1994, Grady Booch used the phrase continuous integration in ''Object-Oriented Analysis and Design with Applications'' (2nd edition) to explain how, when developing using micro ...

Software Performance Testing
In software quality assurance, performance testing is in general a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload. It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as scalability, reliability and resource usage. Performance testing, a subset of performance engineering, is a computer science practice which strives to build performance standards into the implementation, design and architecture of a system. Testing types Load testing Software load testing, Load testing is the simplest form of performance testing. A load test is usually conducted to understand the behavior of the system under a specific expected load. This load can be the expected concurrent number of users on the application software, application performing a specific number of Transaction processing, transactions within the set duration. This test will give out the respo ...

Security Testing
Security testing is a process intended to detect flaws in the security mechanisms of an information system and as such help enable it to protect data and maintain functionality as intended. Due to the logical limitations of security testing, passing the security testing process is not an indication that no flaws exist or that the system adequately satisfies the security requirements. Typical security requirements may include specific elements of confidentiality, integrity, authentication, availability, authorization and non-repudiation. Actual security requirements tested depend on the security requirements implemented by the system. Security testing as a term has a number of different meanings and can be completed in a number of different ways. As such, a Security Taxonomy helps us to understand these different approaches and meanings by providing a base level to work from. Confidentiality * A security measure which protects against the disclosure of information to parties o ...
