Software Testing

Unlike physical systems, most of the defects in software are design errors. Read about the important purpose of software testing and differentiate between verification and validation and basic software testing terms. Compare and contrast the use of various testing strategies, including black-box, white-box, top-down, and bottom-up.

Test Techniques

Techniques based on the nature of the application

The above techniques apply to all types of software. However, for some kinds of applications, some additional know-how is required for test derivation. A list of a few specialized testing fields is provided here, based on the nature of the application under test:

Object-oriented testing
Component-based testing
Web-based testing
GUI testing
Testing of concurrent programs
Protocol conformance testing
Testing of real-time systems
Testing of safety-critical systems (IEEE1228-94)
