Cutthroat competition and customers’ expectation encourages businesses to build more powerful tools by enhancing or adding new features. Whether these changes are small or big, simple or complex, it affects the existing functionality as well and brings unexpected issues. Hence, it is important to test existing features of the application to ensure induction of new changes has not impacted them. This is called “Regression Testing”.

1. BENEFITS OF REGRESSION
TESTING

2.  Cutthroat competition and customers’ expectation encourages businesses to build
more powerful tools by enhancing or adding new features. Whether these changes
are small or big, simple or complex, it affects the existing functionality as well and
brings unexpected issues.
 Hence, it is important to test existing features of the application to ensure induction
of new changes has not impacted them. This is called “Regression
Testing”. Regression testing is indispensable to identify the underlying bugs and
other technical flaws within the software program.
 In its simple terminology, Regression Testing refers to the retesting of the previous
changes to a software program ensuring its optimum efficacy in the current
operating environment. QA testers and web application testing professionals must
understand the benefits of regression testing and use the same extensively.

3.  Testing forms an important part of the application development process to confirm
the apt software coding by the developers. It is a highly technical operation
requiring an immense level of knowledge and experience in software and
application development process.
 Thanks to timely intervention by quality software testers, and use of high-quality
testing tools like actiWate, QTP, Selenium, SilkTest, Rational Functional Tester and
Watir that automatically test the software and prevent any further mess.
 Considering the efforts and time, regression-testing tools are faster, prompter,
safer and more accurate than manual software testing. That’s the reason why
every software firm opts for regression testing tools of its each enhancement,
patches, and configuration changes. It can save 80% in testing – which is far more
difficult and cumbersome than an automated testing.

4. INCREASE MORE TEST COVERAGE IN LESS TIME:
Testing takes the considerable efforts and time to coverage entire
software. However, regression testing executes the selected scenarios
and ensures functionalities work smoothly. Moreover, data inputs or
devices can be changed on every run.
KNOW THE PROBLEMATIC BUGS EARLIER:
Regression testing lets a firm knows which bug is causing problems to
application following the software changes. Engineers can easily modify
or replace the application code with the apt value to remove the bugs.

5. HIGH-QUALITY SOFTWARE:
Regression testing ensures system stability while enhancing the
application continuously. It executes the same steps repeatedly and allows
the team with shorter development cycles by ensuring the high-quality of
software.
INCREASE EFFICIENCY AND COST EFFECTIVE:
Automation of regression test cases allows the firms to keep the cost
low by minimizing the team and involvement of human interaction. At the
same time, resources can focus on more strategic and important tasks.
