Functional software testing verifies that the application
supplies what the users need. It emulates user actions to
ensure that execution paths operate correctly and the
appropriate responses are returned for the given requests. 

Bondary Value Analysis can be defined as " Upper and Lower
Limitation of Variable Data For Particular  Transaction"

Usability Testing

BVA - Boundry Value Analysis is a Form of Functional Testing

ya, good question
B.V.A is the right answer

Hi friends,i am still in confusion as we know BVA is one of 
the test case design technique how could it form a 
functional testing ?Could u plz clear it in detail

Hi Ganesha.,

You might be knowing that Input Domain Coverage is one type
of the Functionality Testing right!!

While Input Domain Coverage itself Test Engineers will
define a special structure to define the Size/Range and Type
of the Objects.

1) Boundry Value Analysis (BVA) 2) Equivalence Class
Partitioning (ECP)

The Question asked is in the given Options which is the part
of Functional Testing. Thus the correct Option is Boundry
Value Analysis.

Thank u So much for clearing and explaining friends

B.V.A is stands for Boundary value Analysis

Functional testing: meet customer requirements in terms of 
functionality

performance testing: testing team validates the "Speed of 
processing" of our app. build

Security testing: testing team validates the "privacy of 
the user"

AS per FOUNDATIONS OF SOFTWARE TESTING book by Dorothy Graham,


Function (or functionality) testing can, based upon ISO 9126, be done focusing on suitability, interoperability, security, accuracy and compliance. Security testing, for example, investigates the functions (e.g. a firewall) relating to detection of threats, such as viruses, from malicious outsiders.

Security Testing,Compliance Testing, Inter-operability Testing etc are various sub-parts of Functional Testing.

Kindly let me know if I am wrong. Thansk for keeping this discussion.
