Modern software products are constantly changing. Improvements and additional functionality are made on a regular basis. Moreover, to be constantly interesting to customers, websites and applications are periodically modified. All this also reflects the dynamics of modern life and constant renewal. However, the constant intrusion into the work of well-coordinated software can lead to failures and the accumulation of errors. To prevent this from happening, it is necessary to carry out software regression testing when making even insignificant changes.
Regression Testing: Overview
Regression testing is the verification of software after making some modifications to it. The program needs to be checked in relation to the correct operation of the original functionality before presenting it to the end customer. Regression testing is necessary to eliminate errors that may have occurred during the integration.
Its main purpose is to detect possible code violations or other errors in those parts of the software that have already been tested before. If such errors, called regression errors, exist, they can break the operations of the underlying functions.
Who Performs Regression Testing
Automated Regression Testing is conducted by the QA team to ensure that all changes were compatible and that no defects appeared. Zappletech https://zapple.tech/ has gathered the best specialists who professionally work on test automation in a variety of projects. Regression testing is one of those tasks that the team does great!
Types of Regression Testing
· Verification tests. This type is used if the bug has already been detected and fixed earlier. When the bug fixing procedure has already taken place, you need to test the program again to make sure that the work done was successful and that no additional errors occurred during it.
· Version verification testing. With each new assembly, it is necessary to check the main functionality of the program in relation to its performance. This is what this type of testing does.
· Regression testing in its purest form involves re-running all tests. This work is carried out regardless of the results of the previous testing. That is, even if no errors and defects were found during the previous testing, regression testing should be carried out again on the same test cases.
· After updating the program, regression testing is also performed to make sure that previous defects do not appear in the updated version.
How Many Times Should Regression Testing Be Done?
So that the end-user does not have problems when starting the program, regression testing is carried out several times. Experts advise running it at least 3-5 times. Not to conduct such a number of tests manually, they need to be automated. Zappletech https://zapple.tech/ does a great job of automating regression tests.
Giving preference to automated regression tests, you simplify the procedure for their implementation and save the working time of valuable QA specialists. This means that you will not have an incentive to run them fewer times than is required for the perfect operation of all your applications. As a result, you will receive quality assurance, and your consumer will not even notice interference with the programs.
