What is a non-functional testing?

Non-functional testing is characterized as a sort of Software testing to check non-utilitarian angles (execution,
ease of use, unwavering quality, and so on) of a product application. It is intended to test the availability of a
framework according to nonfunctional parameters which are never tended to by useful testing.

best, and so forth. 

Accurate numbers are probably not going to be known toward the beginning of the prerequisite procedure 

Essential to organize the prerequisites 

Guarantee that quality traits are distinguished accurately in Software Engineering.
