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.

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.

Retesting

Its a test that on the last occassion u ran it the system filed & now v repear that same test to make sure tat the failure has been eliminated.

Regression testing

V need to check that when changing the faulty code the developer doesnt introduced a new bug into the system. This type of testing is said to be regression teting.

There is a 50 chance of introducing regression faults.

The moral of the regression test says that there will be some risk areas in the software.

Hello All

Regression Testing :

Done after bug fixing and tested once again existing functionality if reflects with changes done due to new CRs or else while fixing the bug.

Re-Testing :

If a tester find any defect then he tested once again if it re-producable or not. for this he once again repeat the same steps..

Let me know if i'm wrong..

Regression testing is any type of software testing which seeks to uncover regression bugs. Regression bugs occur whenever software functionality that previously worked as desired stops working or no longer works in the same way that was previously planned. Typically regression bugs occur as an unintended consequence of program changes.

Retesting: To Test again

Hi Guys..

Re-testing is a process of testing the fix of the bug in the same version or check whether the bug is fixed in the same version.

Regression testing is a process of checking whether the fix of the earlier bug break/effect some area in the application or

process of checking the fixed bugs in the next upgrade version

Hi

Retesting:- after fixed the bug tester will test that perticular buggy module to be ensure whether the bug actully fixed or not that is called Retesting.But to test other related modules functionality to be ensure that whether those related modules functionality affected or not is called regression testing.
