In my point of view ...These are the activities done before the code is developed.Nothing to be executed on computer.It is a static techniques and includesReviews ----- Informal checkingInspection ------Formal Checking Walkthrough ------Guided CheckingAudit -------Sampled checkingIt is a defect prevention bases.It is a construction techniques.
verification is a process of checking , inorder to check whether they are working according to the guidelines are not.in the verification we will give preference for process.
Testing is done to ensure that all the aspects of product are covered which includes Functionality, Robustness, Conformance, Stability, Performance, Usability etc. This is the reason that we have different kind of testing: Negative testing, conformance testing, regression testing, Functional testing, Stress testing.
Verification is sub set of test cases which is required to be perform every time before any product shipment. It will be difficult to run thousands of test case at time of new release due to time & resource constraints, Verification is suppose to finish in shorter duration compare to whole testing.
In perfect world with no time & resource constraints or for Critical project like Aerospace/defense/ Biotech, Verification test suite is same as whole testing suite.
Thank You Very Much everyone for the valuable thougts...
What I got from an authentic web resource is the following:
Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. Software testing also provides 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.
Software testing can also be stated as the process of validating and verifying that a software program/application/product:
1. meets the business and technical requirements that guided its design and development;
2. works as expected; and
3. can be implemented with the same characteristics.
Software testing, depending on the testing method employed, can be implemented at any time in the development process. However, most of the test effort occurs after the requirements have been defined and the coding process has been completed. As such, the methodology of the test is governed by the software development methodology adopted.
Software verification is a broader and more complex discipline of software engineering whose goal is to assure that software fully satisfies all the expected requirements.
There are two fundamental approaches to verification:
• Dynamic verification, also known as Test or Experimentation - This is good for finding bugs
• Static verification, also known as Analysis - This is useful for proving correctness of a program although it may result in false positives
