The document outlines the purpose and objectives of software testing, emphasizing the discovery of programmer-induced problems and the assurance of adherence to standards. It defines various testing types, including functional, parametric, fault-tolerant, integration, and regression testing, each aimed at ensuring that software components work as intended under specified conditions. The goal is to verify that changes in one part of the software do not negatively impact other parts.

1. 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.

2. Examining with a Purpose
Software tests performed to ensure that the
completed program features according to the
objectives defined by the
requirements/specifications.

3. 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.

4. 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.

5. 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.

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

7. 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
