What is Regression Testing?
Regression testing is used to make modifications to older programs and to verify that they still work after the changes have been made. This is an essential part of software design in large companies and is performed by code experts. Old test cases are run against the new version before a new software product is released. This ensures that all old capabilities work. This blog provides additional testing information.
What are The Types of Regression Testing Techniques?
Here are some examples of regression testing techniques:
All Retested
This is one method of Testing where all existing tests are re-executed. It's expensive because it takes a lot of time and resources.
Selection of Regression Tests
It is much better to choose a portion of the test suite that you want to run, rather than re-running an entire suite.
Select cases that have been categorized as
Reusable test cases
Obsolete cases
Reusable test cases that can be used in subsequent Regression cycles. Obsolete test cases are not used in subsequent cycles.
Prioritization of Test Cases
Prioritizing test cases based on business impact, criticality, and frequency of use functionalists is a way to prioritize them. Regression test suites will be significantly reduced if test cases are selected based on priority.
What are the Benefits of Regression Testing?
Modification of requirements and code modifications according to the requirement.
The software has new features.
Fixing defects.
Resolve Performance Issues.
Why Regression Testing Matters?
1. New Functionality: This allows compatibility with both old and new codes whenever new functionality is introduced.
2. Functionality Revision: This revises existing functionality and checks if the feature has been edited or removed, without causing any harm to the functionality.
3. Integration: This ensures seamless integration with another product.
4. Bug Fixing: This involves changing the source code.
5. Increased Quality: This improves the product's quality for a high-quality assurance check.
