What is Mutation testing? When it can be done?

Answer Posted / nitin verma

In mutation testing we create a duplicate copy of the code
that is called as mutant and do some changes in the codes
in the mutant copy and then we test and check weather the
changes are been detected or not and whether it is creating
any effect on the original copy of the code or not.

Plz correct me if i m wrong.

regards
Nitin
