Do you have a reference from Pressman?

Sir i checked this topic in pressman book and this topic is discussed under validation testing concept .

But in this NPTEL video at 16:30 sec, the professor considers alpha,beta, acceptance testing as system testing.

This is confusing...

Answer 1

acceptance testing alpha testing is done at developer site and beta testing at client side

"System testing usually consists of three different kinds of testing activities:
 α – testing: It is the system testing performed by the
development team.
 β – testing: It is the system testing performed by a friendly
set of customers.
 acceptance testing: It is the system testing performed by the
customer himself after the product delivery to determine
whether to accept or reject the delivered product."- According to the book by Rajib Mall

Alpha and beta testings are kind of  Acceptance testing

and Acceptance testing is a kind of System testing .

There should be no doubt about that.

Yaar, no need to complicate things. You might surely have used beta software. They are simply rolled out to check whether users accept the software or not. Not accurate, but I hope you get the point.

Answer 2

Acceptance testing is a kind of System testing 

System testing is a kind of Integration testing ..

Integration testing is a kind of Unit testing .

Hence option A is the correct answer .

see the diagram in this link, it will be clear

What do you mean "Integration testing is a kind of Unit testing"? Once individual software components are unit tested, the whole system is integrated and then integration tests are performed. It is not like "Integration test is a kind of unit test" both are different! Correct it please.
