What is Regression testing? – For many individuals- it might be a new term, or may overlook the importance of regression testing time even after knowing it. 

Since you come to this blog, you must be wondering what is Regression Testing and why it is needed. Also whether it is different from app testing that used to be done while launching an app….

“If you are also curious to know that what is Regression testing, then you need to understand that it is the process of testing software after it has been modified or updated to ensure that the changes do not introduce new bugs or issues. This type of testing is critical to ensure the overall quality and reliability of the software and to prevent unforeseen issues from arising in production environments.”

Well, before we get into the details of this testing technique, let’s take a look at this scenario…

Failing to perform regression testing can result in severe consequences, such as software failures, crashes, data corruption, or security breaches. For example, in 2018, a major update to Microsoft’s Windows 10 operating system caused several issues due to the company’s failure to perform adequate regression testing. The update caused some devices to crash or enter a continuous loop of reboots, rendering them unusable.

Overall, with this example, it is clearly interpreted that app testing holds significant importance in the application development lifecycle. 

But the question is, how many of you taking it seriously?

Launching a buggy app with full-fledged features is nothing but a costly blunder. So as you do app testing before marketing an app, in the same way, regression testing is important while software undergoes often updates. 

And to make it simple and easy, you can hire mobile app developers in India or look for AppsDevPro’s “App Testing and Quality Assurance (QA)”. With the support of highly skilled quality assurance engineers, deeply analyze your app to ensure the highest quality product in the market. The team will make sure that your app updates roll out in the market in the same way as has been envisioned. 

So if you are one of those who have planned for the app updates, then you should read about regression testing in detail. Let’s start with the basics of regression testing…

What is Regression Testing?

Regression testing is a method of software application testing that entails rerunning or retesting a system or application after changes have been made to make sure that the functionality is still working as planned and that any new changes have not resulted in any unexpected consequences or bugs.

The prime aim of considering Regression testing is to identify flaws or bugs that may have entered into the software while changing or upgrading the codes.  It aids in ensuring that the software’s modifications did not significantly impact its current functionality or cause any problems.

Regression testing usually involves executing a set of test cases that cover both the system’s affected areas and are potentially likely to be impacted by the modifications made in coding. To identify any changes or problems, the outcomes of these tests are then compared to those of earlier tests.

As it helps to assure the quality and stability of the product, regression testing is a crucial step in the software development process. Since it is usually done at different points in the development cycle, so hiring a software developer in India is a worthy decision to ensure peace of mind that your product’s quality is in safe hands.
