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

    software development life cycle (SDLC)

    Software development life cycle (SDLC) is a concept used in project management to describe the stages and tasks involved in each step of writing and deploying software. An SDLC model maps the software development process from its initial planning through maintenance and eventual retirement of the completed application.

  • staging environment

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