Regression definition software suite

A lastminute fix, an alreadytested application can break the integrity between two different modules. The regression test suite can also be easily maintained and optimized by monitoring the changes to the test cases. Regression definition is the act or an instance of regressing. A software regression is a software bug that makes a feature stop functioning as intended after a certain event for example, a system upgrade, system patching or a change to daylight saving time. A software performance regression is a situation where the software still functions correctly, but performs more slowly or uses more memory or resources than before.

Changes that may require regression testing include bug fixes, software enhancements, configuration changes, and even substitution of electronic components. Its purpose is to catch bugs that may have been accidentally introduced into a new build or release candidate, and to ensure that previously eradicated bugs continue to stay dead. Even if integration testing is a separate part of the software testing cycle, its test cases should be included in the regression test suite. Using these regression techniques, you can easily analyze the variables having an impact on a topic or area of interest. Regression testing is defined as a type of software testing to confirm that a recent program or code change has not adversely affected existing features regression testing is nothing but a full or partial selection of already executed test cases which are reexecuted to ensure existing functionalities work fine. We have seen an average performance improvement of 5 times on tests in our fault simulation regression suite by using the approximate delay mode of the verifaultxl fault simulator, said ralph marlett, president of atg technology, inc. The regression test suite should be managed properly by continuously updating the test cases. Update the regression suite whenever it is required like if any new defect which is not covered in the test case is found, and a test case for the same should be updated in the test suite so that the testing is not missed for the same next time.
