Is functional testing validation or verification?
      #717935 - 10/12/12 01:03 AM

According to ISO 12207, ALL testing is validation, while static inspection is verification.
In the books or articles, there are two different and contradicting concepts:
1)All testing except for UAT, is verification
2)All testing is validation

Examples e.g. here:
http://www.riceconsulting.com/articles/what-is-UAT.htm

http://www.buzzle.com/articles/validation-testing.html

Is there any official ISO interpretaion? How would you understand it?

Does it really matter?
Testing is testing isn't it?
Most accepted is that Validation is interactive while verification is a passive review of documentation or code. But an accepted practice at your place of employment trumps the general acceptance of any term.

Until a heavenly host directs me to reverse my belief in the norm, I'll continue using the generally accepted terminology thank you very much. You may use anything you like.

I usually talk about everything prior to the build as being verification and everthing to the right of the build validation.
Am I building the right thing (verification)
Did I build it correctly (validation)

But, I know there are flipped definitions out there so your results will vary

Essentially, if you define what you are talking about (in a test plan or SDLC) then I would guess it doesn't matter.
