Functional test vs functional testing terminology issues

manpreet Best Answer 3 years ago

I have been trying to understand these but every article, wiki etc. says something else. My understanding is that:
Functional test means testing of a new functionality in isolation and against docs. Or maybe also exploratory testing?
Funcional testing means validating the application as a whole against specifications only from functional point of view.

And from book, functional testing is said to be a part of System testing when the whole app is tested and checked against Functinal Requirements or design documents.

Could anyone experienced in this field make it clear for me? Thank you
