Regression testing is a sort of software testing used to check for unexpected consequences of program modifications. Regression testing is thus used to ensure that modifications to the software (such as bug patches or new features) do not result in the introduction of any fresh mistakes or issues.
Regression testing is typically carried out by manually running a set of tests that have already been run on the program and comparing the outcomes to those of fresh runs of those tests. If any discrepancies are discovered, it means that the software has undergone a modification that has rendered it broken (or "regressing") from its previously functioning condition.
Businesses must regularly perform regression testing on their products and services to make sure they are operating as intended. Businesses can prevent concerns from developing into larger ones down the road by conducting tests on a regular basis.
Regression testing can also assist companies in enhancing their general quality control procedures. Businesses can ultimately save a great deal of time and money by spotting and resolving possible issues early on.
Regression testing is fundamental to any quality assurance procedure. By spotting potential problems early on, businesses can save a significant amount of time and money in the long run. Additionally, firms can guarantee that their products are of high quality by enhancing their general quality control procedures.
