Unit Testing or Functional Testing? [closed]

manpreet Best Answer 3 years ago

I have recently heard of Functional Testing over Unit Testing.

I understand that Unit Testing tests each of the possibilities of a given piece of code from its most atomic form. But what about Functional Testing?

This sounds to me like only testing if the code works, but is it as reliable as Unit Testing?

I've been told there was two school of thoughts for the matter. Certains would prefer Unit Testing, others Functional Testing.

Is there any good resources, links, books, any references or one of you all who can explain and elighten my path on the subject?

Thanks!
