Acceptance testing of an aircraft catapult Six of the primary mirrors of the James Webb Space Telescope being prepared for acceptance testing In engineering and its various subdisciplines , acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.
In general, acceptance sampling is employed when one or several of the following hold: [2] testing is destructive; the cost of 100% inspection is very high; and; 100% inspection takes too long. A wide variety of acceptance sampling plans is available. For example, multiple sampling plans use more than two samples to reach a conclusion.
A key aspect of specification by example is creating a single source of truth about required changes from all perspectives. When business analysts work on their own documents, software developers maintain their own documentation and testers maintain a separate set of functional tests, software delivery effectiveness is significantly reduced by the need to constantly coordinate and synchronise ...
Acceptance test–driven development (ATDD) is a development methodology based on communication between the business customers, the developers, and the testers. [1] ATDD encompasses many of the same practices as specification by example (SBE), [2] [3] behavior-driven development (BDD), [4] example-driven development (EDD), [5] and support-driven development also called story test–driven ...
Operational testing a jet engine. Operational acceptance testing (OAT) is used to conduct operational readiness (pre-release) of a product, service, or system as part of a quality management system. OAT is a common type of non-functional software testing, used mainly in software development and software maintenance projects. This type of ...
Advanced practices of test-driven development can lead to acceptance test–driven development (ATDD) and specification by example where the criteria specified by the customer are automated into acceptance tests, which then drive the traditional unit test-driven development (UTDD) process. [18]
Acceptance is based on the preceding qualification by reference to the used design / manufacturing documentation. The end of the acceptance process is the approval signature of the customer on the CoA, or QDD, agreeing that all the requirements are met by the product to be delivered under the terms of a contract.
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.
