Distinguishing Points Between Retesting and Regression Testing

The purpose of writing this blog is to understand the difference between retesting V regression testing. To learn more about software testing, choose a good software institution in Pune.

We in the role of a tester do Retesting and Regression testing all our life. Whether we reach on the highest point of stepping stool of this career or has quite recently begun the profession.

Since we individuals are connected with the testing of software applications, we as a whole would be quite acquainted with the word Regression and Retesting. Since both sound comparable and comes enthusiastically soon after a bug-fix, so more often than not we individuals get adhered to the key contrast amongst Retesting and Regression.

In case of regression testing, coders create code test scenarios and activities that will test new units of code after they have been composed. These test cases what turns into the test bucket. Before another rendition of a software product is released, the prior test cases are executed against the latest version to ensure that all the old functions still work. The reason they won’t not work is on the grounds that changing or adding new code to a system can without much of a stretch bring mistakes into code that is not planned to be changed.

Here in case of retesting, your scope is limited. You need to test the functionality which brought about an error and tossed a bug. This sort of testing is done to ensure that the past bug is resolved.

Contrast amongst Regression and Retesting is most eerie software testing question asked in any Interview and we ordinarily get befuddle between Regression testing and Re-testing.

Now let’s move on to the differences between the two. An ideal place is a software course to learn the in and out of these two types of testing.

Regression testing:

  1. This type of testing is the re-execution of the test cases for unaltered part to see that unaltered functionality is working fine or definitely not.

  2. However, in major projects, Retesting and Regression is done in parallel effort. But always remember significance of both in the accomplishment of the venture.

  3. Most of the times, it is an adhoc or general testing.

  4. It is meant for the passed test cases.

  5. The motivation behind regression testing is that new code changes ought not to have any effects to existing functionalities.

  6. Test cases for regression testing can be acquired from the system requirements specification or better known as SRS, manuals and user tutorials and defect reports as to fixed issues.


  1. Retesting is done to ensure that bug is fixed and failed functionality is working fine or not, This is somewhat verification strategy followed in testing field for the fixed bugs.

  2. We ought to dependably remember this, Re-testing has higher priority as compared to regression testing.

  3. This is a planned one amongst the two.

  4. It is meant only for failed test cases.

  5. Re-testing is carried out keeping in mind the defect fixes.

  6. Test cases for this cannot be obtained before the start of testing.

The defect filed by the tester while testing application and same resolved by developer. In Retesting we check same bug whether settled or not utilizing steps to reproduce the said as a part of the defect. In Regression testing we check same bug fixes are not affected other unaltered part of the application, not breaking the usefulness working already and break because of altering deformity.

Both these testing are important to be carried out before delivering any software product to the client or the customer.
