I need you help. I tested one application in that one page have the facility to upload image, it is Photo album page. In that two option Single file upload, Muliple File Upload. In singal file upload you can only upload one file in one time & in multiple file upload you can upload multiple file in one time. In Multiple file Upload link you click add photo link display. using of add photo you can upload multiple file in one time.
My query about-
if after click on multiple file upload link, their is no add photo click present, then this issue about functionality or not.
Please tell me with example about functionality testing.
your query is not an issue, it depend on the requirement how the client need, use can see the multiple upload control so user can know we can upload multiple image or photo, but then also you need to post an issue then you can post as "funtionality not present" or give the suggesstion to implement the "add photo" link.
About the example for functionality testing, if you upload image and you wont able to upload and it shows error then this is a functionality level because your upload functionality is not working as per expected.
This can be marked as functional defect just to highlight the missing functionality. But it has to be marked as Severity - Critical as it is a show stopper because you are not able to execute your test case.
Functional testing generally evaluates the compuatational logic of a program (see B.Beizer, G. Myers, etc.)
The problem you describe might be a funcitonal issue if the logic to submit multiple files is missing or malfunctioning.
However, you also might be experiencing a behaviorial issue in which the button is not being displayed. For example, the functionality is there, but is inaccessible because the developer forgot to include a button control on the page/dialog/property sheet.
