Hi,
In the Mutation testing we create a copy of the original
program that is called as mutant,and we do some changes in
the mutant program and run it with the test cases.After
going through the test cases if the change is being detect
by the test sace then it is called as a 'Killed Mutant' and
if the change did not detect by the test cases then it is
called as 'Equivalent Mutant'. This process is expensive.
Plz correct me if i m wrong....
Thnks n Regards..

Answer / narendra
Mutation testing is done to find the coverage of testcases.
Some mutants will be inserted in the code, then the
negative test cases will be failed.

Answer / kris
A testing methodology in which two or more program
mutations are executed using the same test cases to
evaluate the ability of the test cases to detect
differences in the mutations.
---------------------------------------------
Mutation Testing is a fault-based testing technique
Measure the effectiveness of test cases
Assumption: a program will be well tested if all simple
faults are detected and removed
Simple faults are introduced into the program by creating a
set of faulty version, called MUTANTS
A mutant P’ is a program that is similar to the program P
being tested
It differs from P only by a mutation (mutant operators)
Mutant operators example: Istruction delete, Change of a
constant value, Change of a variable
Test cases are used to execute these mutants with the goal
of causing each mutant P’ to produce incorrect output
If P’ produce different results from P, running the same
test case T  Mutant killed

Monkey testing:-monkey testing is a testing that runs with
no specific test in mind. The monkey in this case is the
producer of any input data (whether that be file data, or
input device data).
Keep pressing some keys randomly and check whether the
software fails or not.
