This document discusses testing fundamentals from the ISTQB Foundation Level certification. It covers why testing is necessary due to software defects and its role in quality. It defines testing as evaluating a system to verify requirements are met and finding errors. The document outlines the testing process including planning, analysis, implementation, evaluation and closure. It also discusses testing principles such as defects will be found, exhaustive testing is impossible, and the importance of early and independent testing.

What is testing ?
1. What is testing ?
There can be different test objectives:
• Finding defects;
• Gaining confidence about the level
of quality and providing
information;
• Preventing defects.

The psychology of testing
1. The psychology of testing
•Tests designed by the person(s) who wrote the software
under test (low level of independence).
•Tests designed by another person(s) (e.g. from the
development team).
•Tests designed by a person(s) from a different
organizational group (e.g. an independent test team).
•Tests designed by a person(s) from a different
organization or company (i.e. outsourcing or certification
by an external body).

What is Testing?
 The word “test” is derived from the Latin word “testum” meaning a
pottery vessel used to measure or assess weight
 Testing is the process of evaluating/measuring a system or system
component by manual or automated means to verify that it satisfies
specified requirements
 Testing is the process of searching for errors, with the goal of finding as
many as possible so that they can be turned over to those responsible
for fixing them
 It is not only sufficient to demonstrate the software is doing what it is
suppose to do, It is equally important to show that software is not doing
what it is not suppose to do
