What is Regression Testing? Examples and Top Business Benefits

Regression testing can be used to measure the effectiveness of the testing process. For example, the number of defects found during regression testing can be compared to the number of defects found during initial testing. If the number of defects found during regression testing is higher, it may indicate that the testing process needs to be improved.

Regression testing can also be used to measure the stability of the software application over time. By tracking the number of defects found during each round of regression testing, developers can identify trends and patterns in the types of defects that are being introduced or fixed. This can help them to focus their testing efforts and prioritize bug fixes.

Examples of Regression Testing

1. Functional Regression Testing: This type of regression testing is done to verify that the existing functionality of the software is still working correctly after any changes or enhancements have been made to it.

2. UI Regression Testing: This type of regression testing is done to ensure that the user interface of the software is still working correctly after any changes or enhancements have been made to it.

3. Integration Regression Testing: This type of regression testing is done to ensure that the software integration with other systems or applications is

still working correctly after any changes or enhancements have been made to it.

Top Business Benefits of Regression Testing

1. Improved software quality: Regression testing maintains software quality and stability over time.

2. Reduced risks and errors: Regression testing helps detect and prevent issues, reducing the risk of costly errors and delays.

3. Faster time-to-market: Regression testing helps ensure faster delivery of software by catching issues early in the development cycle.

4. Increased customer satisfaction: Regression testing helps deliver a highquality product, resulting in higher customer satisfaction.

5. Lower development costs: Regression testing reduces the cost of development by detecting issues early, minimizing the need for expensive fixes later.
