An Expert Guide On Regression Testing

A software regression is any undesired variation that occurs from code changes. Let just take an example of this is you take your vehicle to a mechanic shop to get the air conditioning repaired, and when you get it back, the air conditioning is repaired but now the gas tank sensor stops working. Bummer.

In software, a regression can occur after a new feature is completed. Let’s say an email photo sharing service introduces video adaptability, but after the ability is released, the primary function of sharing photos to a set group of email addresses is completely broken.

Given that a regression is an unintended change, then regression testing is the method of hunting for these changes.

Automated regression testing is a crucial part of improving software quality, and having an effective plan in place is a great idea to reduce software error throughout the software development process.

Best Practices/strategies for Regression Testing

·         Tightly link the regression testing with functional testing & build the regression tests out of successful test cases created & applied during the functional testing.

·         We require identifying the application areas identified to have the high rate of failures & include more regression tests in them.

·         Depending upon the risk factors across the business, we can design the regression test suite. It has been seen that there are specific kinds of failures, which are not expected, but whenever they occur, they leave the serious impact on the business process.

·         For smaller projects, do regression testing after every successful compile or at least once in a week.
