    en.wikipedia.org/wiki/Software_testing

    Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor. [1] Software testing can determine the correctness of software for specific scenarios but cannot determine correctness for all scenarios. [2] [3] It cannot find all bugs.

  3. Software verification and validation - Wikipedia

    en.wikipedia.org/wiki/Software_verification_and...

    Software validation checks that the software product satisfies or fits the intended use (high-level checking), i.e., the software meets the user requirements, not as specification artifacts or as needs of those who will operate the software only; but, as the needs of all the stakeholders (such as users, operators, administrators, managers ...

  4. System testing - Wikipedia

    en.wikipedia.org/wiki/System_testing

    System testing can detect defects in the system as a whole. [citation needed] [1] System testing can verify the design, the behavior and even the believed expectations of the customer. It is also intended to test up to and beyond the bounds of specified software and hardware requirements. [citation needed]

  5. Software release life cycle - Wikipedia

    en.wikipedia.org/wiki/Software_release_life_cycle

    The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public. An example of a basic software release life cycle

  6. Software development process - Wikipedia

    en.wikipedia.org/wiki/Software_development_process

    Testing and quality assurance: To ensure the software's reliability, performance, and security, rigorous testing and quality assurance (QA) processes are carried out. Different testing techniques, including unit testing, integration testing, system testing, and user acceptance testing, are employed to identify and rectify any issues or bugs.

  7. Verification and validation - Wikipedia

    en.wikipedia.org/wiki/Verification_and_validation

    Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.

  8. Software verification - Wikipedia

    en.wikipedia.org/wiki/Software_verification

    Test in the small: a test that checks a single function or class ; Test in the large: a test that checks a group of classes, such as Module test (a single module) Integration test (more than one module) System test (the entire system) Acceptance test: a formal test defined to check acceptance criteria for a software Functional test

  9. Development, testing, acceptance and production - Wikipedia

    en.wikipedia.org/wiki/Development,_testing...

    Development, testing, acceptance and production (DTAP) [1] [2] is a phased approach to software testing and deployment. The four letters in DTAP denote the following common steps: Development: The program or component is developed on a development system. This development environment might have no testing capabilities.
