Regression testing:

Re execution of a selected test case on modified build to
ensure bug fix work and occurances of side effects is
called regression test.

Retesting:

Re executing the same test more than one time with multiple
test data.it is also called iterative or re-testing.


For Example: There are 10 testcases to be passed for a
requirement. But 10th testcase failed and tester raised a
defect in the defect log.

Retesting: After the above defect is fixed, tester need to
execute the 10th testcase to check the expected result for
the same.

Regression Testing: After the above defect is fixed, tester
need to execute the 20% of above testcases by selecting
randomly to make sure that existing functionality is not
broken because of the above fix.

negative inputs i.e. executing one fuctional test case with
different sets of data.
