Understanding the Role of Regression Testing Services and How it is Performed
                     Understanding the Role of Regression Testing 
Services and How it is Performed 
What is Regression Testing Services?
Mobile applications, websites, and Software are updated frequently to introduce new 
features in software. This process of updating a software introduces new bugs in software. 
Regression testing services make sure that the new software works the way it is intended to 
work without any glitches or errors. Before delivering a new version of a software, old test 
cases run on a new version to assure that old features are working fine even after a software 
update. 
Techniques Utilized by Regression Testing Services :
        
Retest All
It is one of the practices of this testing in which each test in an existing test suite re-executed. 
It is expensive as it needs plenty of time as well as resources.
Regression Test Preference
• Rather than re-executing a complete test suite, it is more useful to choose the part of the 
test suite to run –
• Test chosen cases described as
• Reusable Test samples
• Obsolete Test samples
• Reusable Test samples used in succeeding Regression cycles. Obsolete Test samples not 
used in succeeding cycles.
How does Regression Testing Work?
This testing is done manually. Though, as application development demands time, more and 
more functionality retains expanding the scope of regression; hence, this testing is conducted 
in an automated way.
While developing a test suite for regression, take the following into consideration–
• Automate all the test proceedings of a test set.
• Renew the regression suite when needed like if any new defect which not covered in a 
test case found, update test case for that matter in a test suite. Conduct testing for a bug 
and reveal next time.
• Accomplish regression test cases, whenever modifications made in code, implement bug 
fixing, new functionality added, and also an improvement to existing functionality done.
• Create a test performance report which comprises pass/fails status of completed test 
cases.
Advantages of Regression Testing :
Change in specifications and code altered according to the specification.
New characteristic added to the software.
Bug fixing.
Fix the Performance issues.
Why Regression Testing Matters?
New Functionality – It enables adaptability with old and new code whenever new features 
are added.
Functionality Revision – It changes the existing functionality and checks if the feature 
updated or eliminated without creating any disturbance to the functionality.
Bug Fixing – Bug fixing needs modifying the source code done by Regression Testing.
Improved Quality – It increases the quality of the product for high-quality Assurance check.
How to Adopt Regression Testing?
The following circumstances needed to be taken into consideration–
• Analyse modifications made to the software.
• Analyse and discover what elements of software might be affected.
• List a time to test.
• Regression Testing Tools
3) Manual Regression testing wastes time and cost. Automated tested is being adopted by 
testers globally to save time and cost. 
For this, some tools are mentioned as follows –
4) Selenium – It is a free tool used for automating web apps. Selenium also used for 
browser-based Regression Testing.
Quick Test Professional – HP QuickTest Professional, is automated software created to 
automate functional and regression test cases. It presents the performance of Vb Script 
language for automation.
