Software testing - is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include, but are not limited to, the process of executing a program or application with the intent of finding software bugs (errors or other defects).
Verification - The process of evaluating work-products (not the actual final product) of a development phase to determine whether they meet the specified requirements for that phase.
Validation - The process of evaluating software during or at the end of the development process to determine whether it satisfies specified business requirements.
Error: A discrepancy between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition.
Failure: The inability of a system or component to perform its required functions within specified performance requirements. See: bug, crash, exception, and fault.
Fault: An incorrect step, process, or data definition in a computer program which causes the program to perform in an unintended or unanticipated manner. See: bug, defect, error, exception.
Defect: Commonly refers to several troubles with the software products, with its external behavior or with its internal features.
TESTING OBJECTIVES:
- Testing is a process of executing a program with the intent of finding an error.
- A good test case is one that has a high probability of finding an as yet undiscovered error.
- A successful test is one that uncovers an as yet undiscovered error.
Testing should systematically uncover different classes of errors in a minimum amount of time and with a minimum amount of effort. A secondary benefit of testing is that it demonstrates that the software appears to be working as stated in the
