INTRODUCTION It is the process used to identify correctness, completeness
and quality of developed computer software.
It is the process of executing the program/application under positive or negative conditions by manual or automated means. It checks for the:-
Specification Functionality Performance

OBJECTIVES
• Discover as many errors or bugs as possible in a product.• Demonstrate a given software product matching its
requirement specification.• Validate the quality of a software testing using the minimum
cost and efforts.• Generate high quality test cases, perform effective tests and
issue correct and helpful problem reports.

ERROR, BUG, FAULT & FAILURE
Error: It is a human action that produces the incorrect result that produces a fault.
Bug: The presence of error at the time of the execution of the software.
Fault: State of software caused by an error.
Failure: It is the deviation of the software from its expected results. It is an event. BACK

Validation: The system should do what the user really requires(Are we building the right product?).

White Box Testing
Knowledge of the internal program design or code required.

DISCUSSION In order to be cost effective, testing must be
concentrated on areas where it will be more effective.
The absence of an organizational testing policy may result in too much efforts and money will be
spent on testing.
