A method whereby purposely inserted erros into a
programming code under test to verify that the detect the
defect. It is also known as error seeding.

Hi,
In the mutation testing we create the mutants(duplicate
copy) and then we test on the mutants and finds whether any
difference is there between the mutants and the original
program after the test.

Plz comment if i m wrong......

Answer / jeekarthik

oh!!!! Kewl the topic now entered into Debugging!!!! :-)

After the initial testing is complete, mutation testing is
taken up. The idea behind mutation testing is to make a few
arbitrary small changes to a program at a time, each
time the program is changed it is called a mutated program;
the change is called a mutant.

A mutated program tested against the full test suite of the
program. If there at least one test case in the test suite
for which a mutant gives an incorrect result, then the
mutant is said to be dead.

If a mutant remains alive even after all test cases have
been exhausted, the test suite is enhanced to kill the
mutant.

The process of generation and killing of mutants can be
automated by predefining a set of primitive changes that
can be applied to the program.

The primitive changes can be:
? Altering an arithmetic operator,
? Changing the value of a constant,
? Changing a data type, etc.

A major disadvantage of mutation testing:
? computationally very expensive,
? A large number of possible mutants can be generated.

Valid?????? :-)

Answer / ch.s.m.prasad,kkd

Mutation means a known change in a program. during this
testing developers will check whether all modules are
participating or not while executing the program.

Poonam,
I think lot of diff is there between debugging and mutation.
i deffinetely consider you and suneel suggetions, today i
will discurse with my team and i will let you know.
Thanks,

Answer / rajesh.veggalam

Mutation test means a change in your program programmers
are perform changes in tested programs to estimate
completeness and correctness of the program testing

Answer / sreenivasu

Mutation means a change in a program. Programmers are
performing changes in programs to estimate correctness of
testing coverage.

For eg: one test passed, then apply certain change in that
particular program and test it... if the result is failed
then we can say it as a mutation testing i.e a change
should affect the result ..

Answer / bali

straight,Purposefully introducing the bug in the
application and checking the the variation in the expected
result. this is Mutation testing or bebugging, No
confusions.

Just remember we are intentionally introducing the bug......

Answer / logu

Mutation testing means introduse the new bug and clear that
bug and testing the application
