is functional and black box testing same or not

Answer Posted / mohit tyagi

as per my views i think functional testing is a part of
black box testing.
in black box testing we perform two types testing
1)Functional Testing
2)Non Functional Testing
Functional Testing is performed to check functionalities of
a system(e.g. login, searching, inserting data etc.)
Non-Functional Testing is performed to check Non-functional
Requirements of the system(e.g. Stress, load,
usability,installation, configuration testing etc.)

so in functional testing we just test functionalities of a
system whether in black box testing we check both functional
as well as non-functional requirements of a system.

pls correct me if i m wrong.
