ReplyDeleteHi Guys,
ReplyDeleteLast week I attended an Interview and the Interviewer asked me who does Integration Testing.
I told it would be done by Developers after Unit Testing is done inorder to verify whether the functionality is working fine or not
Then the build would come to Testers
But he told me that it wont be done by developers
Could anyone help me out
