That's right, Srikar!!
Adding to it..

With mutation testing, the system/program under test is
changed to create a faulty version called a mutant. You
then run the mutant program through a suite of test cases,
which should produce new test case failures. If no new
failures appear, the test suite most likely does not
exercise the code path containing the mutated code, which
means the program isn't fully tested. You can then create
new test cases that do exercise the mutant code.

Hi,
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.If the
changes are being detected then it is called as killed mutant.

Plz correct me if i m wrong..

Answer / prasanna

This is one of the White Box Testing Technique . Generaly
programmer are following this tehnique to test the change
in the programme t estimate the correctness & completeness
of the programme.

for example
1. if all tests passed in the programme that is good
programme.
2. If all tests passed but in the programe some change is
there .don't say passed. this is not a good teting
3. in alltests passed except change test failed. this is
the complete testing.

Mutation testing also called mutation analysis is a method
of software testing, which involves modifying program's
source code in small ways. These, so-called mutations, are
based on well-defined mutation operators that either mimic
typical user mistakes (such as using the wrong operator or
variable name) or force the creation of valuable tests. The
purpose is to help the tester develop effective tests or
locate weaknesses in the test data used for the program or
in sections of the code that are seldom or never accessed
during execution.

In software testing we intentionally introduce some bugs in
the code and test whether that bugs are detected or
not..This is called Mutation Testing.
