ďƒ˜

ďƒ˜

Gaining assurance in and offering information about the standard.

Examining with a Purpose

ďƒ˜

Software tests performed to ensure that the completed program features according to the objectives defined by the requirements/specifications.

Definition of Testing Types ďƒ˜

ďƒ˜

Functional Testing Module testing confirms that each program device works as predicted according to the needs using a small part of possible feedback factors.

ďƒ˜

ďƒ˜

Parametric Testing At the component stage, testing confirms that each program device works as predicted according to the needs for the wide variety of legitimate feedback factors.

ďƒ˜

ďƒ˜

Fault Tolerant Testing Module testing confirms that each program device does not perform in a bad or surprising way for unlawful or out-of-range feedback factors.

ďƒ˜

ďƒ˜

Integration Testing Integration tests an additional step that is used when different sub-systems are being developed at the same time by independent designers.

ďƒ˜

ďƒ˜

Regression Testing Regression tests retesting subsystems/modules/units to guarantee that variations to one sub-system/module/unit does not cause surprising results in another subsystem/module/unit
