Software Test Design Definitions

  • A

    alpha testing

    Alpha testing is the initial phase of validating whether a new product will perform as expected. Alpha tests are carried out early in the development process by internal staff and are followed up with beta tests, in which a sampling of the intended audience actually tries the product out.

  • B

    black box (black box testing)

    Black box testing assesses a system solely from the outside, without the operator or tester knowing what is happening within the system to generate responses to test actions.

  • E

    end-to-end testing

    End-to-end testing is a methodology that assesses the working order of a complex product in a start-to-finish process.

  • G

    gray box testing (gray box)

    Gray box testing, also called gray box analysis, is a strategy for software debugging based on limited knowledge of the internal details of the program. A gray box is a device, program or system whose workings are partially understood.

  • M

    model-based testing

    Model-based testing (MBT) requires a test team to create a second, lightweight implementation of a software build- typically only the business logic - called the model.

  • model-driven development (MDD)

    Model-driven development (MDD) is a format to write and implement software quickly, effectively and at minimum cost.

  • P

    PERT chart (Program Evaluation Review Technique)

    A PERT chart is a project management tool used to schedule, organize, and coordinate tasks within a project.

  • S

    staging environment

    A staging environment, or staging, provides a nearly exact replica of a production environment for software testing.

  • systems development life cycle (SDLC)

    The systems development life cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an information system development project, from an initial feasibility study through maintenance of the completed application.
