Verification is a static testing procedure. |
Validation is dynamic testing procedure. |
|
2. |
It involves verifying the requirements, detailed design documents, test plans, walkthroughs and inspections of various documents produced
during the development and testing process. |
Validation involves actual testing of the product as per the test
plan (unit test, integration test, system test and acceptance test etc). |
|
3. |
It is a preventive procedure. |
It is a corrective procedure.
|
|
4. |
Are we building the product RIGHT?
|
Are we building the RIGHT product? |
|
5. |
It involves more then two to three persons and is a group activity. |
It involves the testers and sometimes user. |
|
6. |
It is also called Human testing, since it involves finding the errors by persons participating in a review or walk through. |
It is also called Computer testing, since errors are found out by testing the software on a computer. |
|
7. |
Verification occurs on Requirements, Design and code. |
Validation occurs only on code and the executable application.
|
|
8. |
Verification is made both in the Executable and Non Executable forms of a work product |
Validation is done only on Executable forms of a work product.
|
|
9. |
Verification finds errors early in the requirement & design phase and hence reduces the cost of errors. |
Validation finds errors only during the testing stage and hence cost of errors reduced is less than Verification.
|
|
10. |
An effective tool for verification tool is a Checklist.
|
Various manual and automated test tools are available for Validation. |
|
11. |
It requires cooperation and scheduling of meetings and discussions. |
It is to check that the product satisfies the requirements and is accepted by the user.
