Purpose And Objectives Of Software Testing

Discovering problems which may get created by the programmer while developing the application.

Gaining assurance in and offering information about the standard.

Examining with a Purpose

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

Definition of Testing Types

Functional Testing

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

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.

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.

Integration Testing

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

Regression Testing

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