Regression Testing: Compendious Guide

Web Development, like all other Digital Marketing tools, is dynamic. That means that even after days or months are spenton a particular project, the developer can’t rest assured that their product will be in its original form for the rest of its operational life.

Companies, from time to time, keep on updating their products. Thus, it is a safe practice to ensure that the application is free from bugs and security flaws. These minor fixes, patches, and updates affect the way an application performs and sometimes can also alter its stability. As a result of which, developers need to continuallyconduct tests on the code of these applications to make sure it is ready and free from performance issues. These series of ongoing tests are termed regression testing.

The beauty of regression testing lies in the fact that the developer implements units of code continually in the master code of an application and the software tester tests the solution to make sure that the application is running as it should in the long run. It enables the coder to guarantee that the patch introduced will not affect the functionality of the software in any way.

Even though veteran coders are aware of functional testing, they are also, always ready for surprises while code is handed over to the software testing expert! Conducting regression testing might seem arduous at times,but it is the only way to steer clear of unwanted complications during the lifetime of an application.

Key Benefits of Regression Testing Services

A software testing company knows that the reason behind carrying out software testing services is to make sure that software product is free from defects, especially after introducing a new unit of code in the master code.

The Regression Testing has a number of benefits. Some of them are listed below:

• Identification of undesired effects on the application that can result in unexpected results.
• Early identification of bugs which are generated because of changes in the code.
• To assure each module of the software works as per expectations.
• Making sure that the application is performance optimized and will not crash the system in case of excessive load.
• It is beneficial in cases where the code continuouslygoes through changes to meet the directives of the client
• Assists the QA experts to maintain optimum quality in their products

Types of regression testing

Regression testing is part of functional software testing services. It can be carried out in different ways by the software testing experts or developers. Top 3 types of regression testing are discussed in brief in the following section:

1. Corrective regression testing:

It is the go-to-method applied by developers when no significant changes are introduced into the specification of the product.

2. Retest-all regression testing:

It is an arduous method and requires a lot of time to complete. It involves testing all of the aspects of a particular application. The software testerreuses the datapoints collected during initial tests beforethe launch of the product even if significant modifications are not introduced in the master code.

3. Selective regression testing:

Selective regression testing is a method that is adopted by QA testing experts to analyze whether the new unit of code introduced in the master code is affecting the functionalities of the application in any way.

End Note:

Regression testing is one of the most important parts of software development and quality assurance cycles. It has many benefits and it has to be used rigorously.
