Validation
Establishing documented evidence which provides a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes. Validation typically involves actual testing and takes place after verifications are completed.
Validation (Product Oriented)
Validation is concerned with whether the right functions of the program have been properly implemented, and that this function will properly produce the correct output given some input value.
The process of evaluating software to determine compliance with specified requirements.
Validation ensures that functionality, as defined in requirements, is the intended behavior of the product; validation typically involves actual testing and takes place after verifications are completed.
Code inspection
A manual [formal] testing [error detection] technique where the programmer reads source code, statement by statement, to a group who ask questions analyzing the program logic, analyzing the code with respect to a checklist of historically common programming errors, and analyzing its compliance with coding standards. Contrast with code audit, code review, code walkthrough. This technique can also be applied to other software and configuration items.
Code review
A meeting at which software code is presented to project personnel, managers, users, customers, or other interested parties for comment or approval. Contrast with code audit, code inspection, code walkthrough.
Code walkthrough
A manual testing [error detection] technique where program [source code] logic [structure] is traced manually [mentally] by a group with a small set of test cases, while the state of program variables is manually monitored, to analyze the programmer's logic and assumptions. Contrast with code audit, code inspection, code review.
Mean
A value derived by adding several qualities and dividing the sum by the number of these quantities.
Measurement
The act or process of measuring. A figure, extent, or amount obtained by measuring.
Cause effect graph
A Boolean graph linking causes and effects. The graph is actually a digital-logic circuit (a combinatorial logic network) using a simpler notation than standard electronics notation.
Cause effect graphing
(1)Test data selection technique. The input and output domains are partitioned into classes and analysis is performed to determine which input classes cause which effect. A minimal set of inputs is chosen which will cover the entire effect set.
(2)A systematic method of generating test cases representing combinations of conditions.
