Rapidly advancing digital world always demands high-quality software applications. This scenario is also creating a tough competition between the software engineering firms to develop unique as well as custom-made software products as per their customer needs.
Developing a software and just delivering it doesn’t end the software development process. The main problem is that in a day to day scenario, many software products are delivered without proper testing.
This practice poses a huge threat to the businesses because if appropriate testing is not carried out for the software products before they are delivered, they can cause huge loss.
With the continuous increase of online customers, businesses are forced to run high performing websites or web applications, so, the faulty software can prove to be fatal.
However, we as online customers would like to visit a website that is equipped with fully functional features. Also, our requirements, as well as trends, change from time to time.
So, with changing customer mindsets and usage patterns, businesses continuously change features or upgrade features of an application.
But there is always a great chance that if any change is made to an application, there is always a possibility that it can affect the other features of an application too.
In this rapidly developing scenario, businesses need to make sure that their online business platforms are up and running always without interrupting customer usage.
To be up and running, proper testing needs to be done to assure the application is of good quality. So, it is always a right approach to start testing along with the development of the applications.
Functional testing is the basic procedure that has to be performed for every component of a software product.
And when any component is integrated to an application, regression testing has to be performed to make sure that the change is not affecting any other component or any portion of an application.
Today, Agile Methodology is the most common approach for any software engineering firm that makes frequent releases to production with new changes every time in each release.
Regression testing is the mandatory thing that has to be done after any improvement or when any new functionality is implemented in an application. Regression testing plays a vital role in any of the testing processes, as it re-tests the already working parts of an application after each release.
We often come across a situation when one might wonder as to why to test a code again that have already passed and did not result in any bugs, but when repeated results in some new bugs. The reason might be that a new code has broken the previously working functions or have introduced errors or created bugs.
It is crucial for a testing team to make sure that other functional parts in an application are still working fine as expected before the application goes to production. This is the reason that Regression testing should be considered and carried out seriously.
Also, Regression testing should be taken as a very important testing activity as if they are testing a feature for the first time.
We are in the era of ‘Agile Development,’ and it needs fully functional features to be created in relatively short time-frames.
Gone are the days of creating lengthy documentations. Regardless of the length of a sprint, proper testing must be performed before a feature can be declared as completed.
Regression testing includes executing an increasing set of tests along with covering existing functionality until the product is done. Thus, continuous regression testing helps software development teams build software that behaves as intended and is perfectly stable.
No matter what is the size of the project or its deadlines Regression testing should be the norm and the testing team should always follow “Test after change and Test often” approach. This will not only provide the results that inform whether the new code is compatible with the existing code base or not, it will also help the team to come out with a flawless product.
