Test Strategy
A test strategy is an outline that describes the testing approach of the software development cycle. The purpose of a test strategy is to provide a rational deduction from organizational, high-level objectives to actual test activities to meet those objectives from a quality assurance perspective. The creation and documentation of a test strategy should be done in a systematic way to ensure that all objectives are fully covered and understood by all stakeholders. It should also frequently be reviewed, challenged and updated as the organization and the product evolve over time. Furthermore, a test strategy should also aim to align different stakeholders of quality assurance in terms of terminology, test and integration levels, roles and responsibilities, traceability, planning of resources, etc. Test strategies describe how the product risks of the stakeholders are mitigated at the test-level, which types of testing are to be performed, and which entry and exit criteria apply.

Software Development Process
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management. The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application. Most modern development processes can be vaguely described as agile. Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming. A life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" is a particular instance as adopted by a specific organization. For example, many specific software development processe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regression Testing
Regression testing (rarely, ''non-regression testing'') is re-running functional and non-functional tests to ensure that previously developed and tested software still performs as expected after a change. If not, that would be called a '' regression''. Changes that may require regression testing include bug fixes, software enhancements, configuration changes, and even substitution of electronic components ( hardware). As regression test suites tend to grow with each found defect, test automation is frequently involved. Sometimes a change impact analysis is performed to determine an appropriate subset of tests (''non-regression analysis''). Background As software is updated or changed, or reused on a modified target, emergence of new faults and/or re-emergence of old faults is quite common. Sometimes re-emergence occurs because a fix gets lost through poor revision control practices (or simple human error in revision control). Often, a fix for a problem will be " fragil ...

Test Plan
A test plan is a document detailing the objectives, resources, and processes for a specific test session for a software or hardware product. The plan typically contains a detailed understanding of the eventual workflow. Test plans A test plan documents the strategy that will be used to verify and ensure that a product or system meets its design specifications and other requirements. A test plan is usually prepared by or with significant input from test engineers. Depending on the product and the responsibility of the organization to which the test plan applies, a test plan may include a strategy for one or more of the following: * Design verification or compliance test – to be performed during the development or approval stages of the product, typically on a small sample of units. * Manufacturing test or production test – to be performed during preparation or assembly of the product in an ongoing manner for purposes of performance verification and quality control. * Acceptanc ...

Test Case
In software engineering, a test case is a specification of the inputs, execution conditions, testing procedure, and expected results that define a single test to be executed to achieve a particular software testing objective, such as to exercise a particular program path or to verify compliance with a specific requirement. Test cases underlie testing that is methodical rather than haphazard. A battery of test cases can be built to produce the desired coverage of the software being tested. Formally defined test cases allow the same tests to be run repeatedly against successive versions of the software, allowing for effective and consistent regression testing. Formal test cases In order to fully test that all the requirements of an application are met, there must be at least two test cases for each requirement: one positive test and one negative test. If a requirement has sub-requirements, each sub-requirement must have at least two test cases. Keeping track of the link between ...

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] |
Senior Management
Senior management, executive management, or upper management is an occupation at the highest level of management of an organization, performed by individuals who have the day-to-day tasks of managing the organization, sometimes a company or a corporation. Overview Executive managers hold powers delegated to them with and by authority of a board of directors and/or the shareholders. Generally, higher levels of responsibility exist, such as a board of directors and those who own the company (shareholders), but they focus on managing the senior or executive management instead of on the day-to-day activities of the business. The executive management typically consists of the heads of a firm's product and/or geographic units and of functional executives such as the chief financial officer, the chief operating officer, and the chief strategy officer. In project management, senior management authorises the funding of projects. Compare: Senior management are sometimes referred to, ...

Traceability Matrix
In software development, a traceability matrix (TM) is a document, usually in the form of a table, used to assist in determining the completeness of a relationship by correlating any two baselined documents using a many-to-many relationship comparison. It is often used with high-level requirements (these often consist of marketing requirements) and detailed requirements of the product to the matching parts of high-level design, detailed design, test plan, and test cases. A requirements traceability matrix may be used to check if the current project requirements are being met, and to help in the creation of a request for proposal, software requirements specification, various deliverable documents, and project plan tasks.Carlos, Tom (October 21, 2008). Requirements Traceability Matrix - RTM. PM Hut, October 21, 2008. Retrieved October 17, 2009 from http://www.pmhut.com/requirements-traceability-matrix-rtm.

Low-level Design
Low-level design (LLD) is a component-level design process that follows a step-by-step refinement process. This process can be used for designing data structures, required software architecture, source code and ultimately, performance algorithms. Overall, the data organization may be defined during requirement analysis and then refined during data design work. Post-build, each component is specified in detail. The LLD phase is the stage where the actual software components are designed. During the detailed phase the logical and functional design is done and the design of application structure is developed during the high-level design phase. Design phase A design is the order of a system that connects individual components. Often, it can interact with other systems. Design is important to achieve high reliability, low cost, and good maintain-ability. We can distinguish two types of program design phases: * Architectural or high-level design High-level design (HLD) explain ...

High-level Design
High-level design (HLD) explains the architecture that would be used to develop a system. The architecture diagram provides an overview of an entire system, identifying the main components that would be developed for the product and their interfaces. The HLD can use non-technical to mildly technical terms which should be understandable to the administrators of the system. In contrast, low-level design further exposes the logical detailed design of each of these elements for use by engineers and programmers. HLD documentation should cover the planned implementation of both software and hardware. Purpose * Preliminary design: In the preliminary stages of system development, the need is to size the project and to identify those parts which might be risky or time-consuming. * Design overview: As the project proceeds, the need is to provide an overview of how the various sub-systems and components of the system fit together. In both cases, the high-level design should be a comple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Server (computing)
A server is a computer that provides information to other computers called " clients" on a computer network. This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients or performing computations for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Client–server systems are usually most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgment. Designating a computer as "server-class hardwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aesthetics
Aesthetics (also spelled esthetics) is the branch of philosophy concerned with the nature of beauty and taste (sociology), taste, which in a broad sense incorporates the philosophy of art.Slater, B. H.Aesthetics ''Internet Encyclopedia of Philosophy,'' , accessed on 15 September 2024. Aesthetics examines values about, and Critical thinking, critical judgments of, artistic taste and preference. It thus studies how Artist, artists imagine, create, and perform works of art, as well as how people use, enjoy, and criticize art. Aesthetics considers why people consider certain things beautiful and not others, as well as how objects of beauty and art can affect our moods and our beliefs. Aesthetics tries to find answers to what exactly is art and what makes good art. It considers what happens in our minds when we view Visual arts, visual art, listen to music, read poetry, enjoy delicious food, and engage in large artistic projects like creating and experiencing plays, fashion shows ...

Train Ticket
A train ticket is a transit pass ticket issued by a railway operator that enables the bearer to travel on the operator's network or a partner's network. Tickets can authorize the bearer to travel a set itinerary at a specific time (common for long-distance railroads), a set itinerary at any time (common for commuter railroads), a set itinerary at multiple times, or an arbitrary itinerary at specific times. The last two categories are often called ''passes'': the former is often sold as a discounted block of trips for commuters; the latter is often sold to vacationers, such as European Eurail passes. In some countries, like Italy, and some local railways in Germany, conductors are not used. Instead passengers are expected to validate tickets in a special stamping machine before entering the train. A system of coupons that are validated with a special machine exists on the Mumbai Suburban Railway where combinations of coupons of denominations are used to get the correspondi ...
