Quality Assurance: All those planned or systematic actions necessary to provide adequate confidence that a product or service is of the type and quality needed and expected by the customer.

Quality Control: The operational techniques and the activities used to fulfill and verify requirements of quality.

Testing :

  • The process of exercising software to verify that it satisfies specified requirements and to detect errors.
  • The process of analyzing a software item to detect the differences between existing and required conditions (that is, bugs), and to evaluate the features of the software item (Ref. IEEE Std 829).
  • The process of operating a system or component under specified conditions, observing or recording the results, and making an evaluation of some aspect of the system or component

    Testing >> Process of executing a system with the intent of finding defects including test planning prior to the execution of the test cases.

    QC >> A set of activities designed to evaluate a developed working product.

    QA >> A set of activities designed to ensure that the development/maintenance process is adequate to ensure a system will meet its objective.

    IN short >>

    QC is the superst of testing and QA is superset of QC.
