Regression Software Testing Services

Regression testing is a set of tests aimed at detecting defects in the areas of the application that have already been tested. This is not done at all in order to finally verify the absence of bugs, but to find and correct regression errors. Regression errors are the same bugs, but they do not appear when writing a program, but when adding a new section of the program to the existing one or fixing other bugs, which caused new defects in the already tested product.

Thus, we can say that the goal of regression testing is to make sure that fixing some bugs did not cause others to arise and that updating the build did not create new defects in the already validated code.

Here are several types of regression tests:

– Verification tests. To be carried out to check the correction of the detected and previously opened bug.

– Test version verification. It contains the principles of smoke testing and assembly testing: testing the functionality of the main program functionality in each new assembly.

– Direct regression testing itself – re-execution of all tests that were written and conducted earlier. They are performed according to already existing test cases, regardless of whether bugs were found during their passage, or not.

– Testing in the new build of already fixed bugs in old builds. This is done in order to check if the upgrade of the old defect build has been renewed.

Some provisions on how to conduct regression testing:

– This type of testing is conducted in each new build.

– You need to start with version verification (assembly testing and smoky testing).

– Check for corrected bugs.

– Regression testing, in general, does not cover the whole application, but only those areas that in some way or other are “in touch” with changes in the build.

Further, the previously closed bugs are tested.

1) Regression testing is recommended several times (3-5). Therefore, in order to save valuable time (and, perhaps, to get rid of “routine”), the power of test automation is actively used in regression tests.

2) Conducting the final regression testing, for which the tests are selected according to the priority determined by the greatest number of errors found.

Also, regression testing is actively used in extreme development.
