We live in an omnichannel world which provides broader communication opportunities to reach the target audience. However, this brings the challenge of investing in overhead to support multiple channels and respect customer delivery preferences, while simultaneously trying to deliver relevant and consistent communications. These challenges require organizations to continuously evolve to achieve hyper-personalized, fluid communication. Regression testing helps ensure that code upgrades haven't affected the customer experience (CX). Unfortunately, many businesses view this process as superfluous when updating document modifications. When it comes to CX, however, it can benefit businesses by lowering costs through an effective and efficient proactive approach to resolving bugs introduced by changes. You can read more about regression testing automation and its impact on CX in my previous blog.

When should regression testing be performed?

Introduction of a new function

Regression testing ensures that even though the code has changed, the existing features and functions still work as intended. Regression testing needs to be performed every time a new requirement is introduced and then to verify whether all the previous, unchanged logic or conditions are working fine. This involves re-testing those parts of the application which are unchanged.

Modifications to documents

Regression testing must be done every time a document is modified to make sure the changes maintain effective communication and a positive customer experience.

Follow up after debugging a system

Fixing one bug can result in additional bugs in unexpected codebase areas. Debugging entails making significant changes to source code, monitoring bug status, and repeating. This emphasizes the significance of regression testing after debugging to ensure fixing one bug didn't cause more problems than it fixed, and everything works as intended.

How to develop an effective regression testing strategy?

To ensure your documents remain bug-free even after incorporating modifications, we adopt the following strategy:

• The first step is to gather and methodically examine the requirements of the client to be sure there is a clear understanding of the client’s vision.
• The next step in the process is to create test data when and where required.
• After mapping the business requirements, we help in creating a base PDF sample with the approval of the client using standard stress data. In case of any new change or modification in the standard setup, we use the same approved PDFs as a base file for the execution of regression testing.    
• The two PDFs are then compared to identify any unintended changes in the document.
• Finally, the QC findings are logged in the JIRA tickets and regression testing is done to rectify the issues.

The ultimate value

Any investment in CCM should ultimately deliver value to the customer. The value can be in speed, efficiency, accuracy, or performance. Using regression testing, enterprises can ensure all these parameters are met, generating the utmost customer satisfaction. The partner you choose for any CCM initiative must ensure minimum disruption and guarantee that the new features or enhancements to the document do not cause any unintended negative impact on the existing quality.
