What is Regression Testing? What Are Some Examples?

Regression testing is all about the confirmation of web application has not affected existing features of that program. Its nothing but a full or partial selection of already executed cases which are re-executed to ensure previous functionalities are working fine or not.

Why Regression Testing Needed?

The main requirement for regression testing is:

• When new changes are done in software.
• If the change in code is required.
• Defect fixing
• Fixing performance issues of code

How to do Regression Testing

Software testing is an activity which is compulsory to each and every software before its final launch. It includes error correction, enhancements, optimization and deletion of existing features. It can be done by the following features.

Types of Regression Testing

1. Reset All

In this section, all the test in the existing task should be re-executed.

2. Regression Test Selection

3. Prioritization of Test Cases

Depending on the functionality of the software, prioritize the test cases and impact on business.

Selecting Test Cases For Regression Testing

According to the survey defects fixed in may lead to failure of the software product. Effective testing may lead to the following steps.

• Cases with frequent defects.
• Cases with core features of the product
• Recent changes in functionalities
• All integration test cases
• All complex test cases
• Boundary value test cases.

Tools Used For Regression Testing

If your software has to make sudden changes, regression testing may escalate. In such cases, testing may cost high.

Below are the most important tools used in testing

Conclusion :

An effective regression testing, save the company’s money and time and helps to run the software efficiently.
