Summary: QA Testing Services play a critical role in a software's online success. The testing phases ensure the smooth functioning of the development lifecycle. The timely elimination of bugs, coding errors, loading problems, etc. is managed seamlessly. One of the best QA Testing Services that we are going to discuss in this blog is 'regression testing.'
Introduction To The World Of Software Testing Service
Quality Assurance is all about defect prevention. For instance, a user is looking at a website that looks fine at first, but scrolling or switching pages gives you design flaws & errors. These minute functionalities make it a point for every online venture to go for end-user responsiveness.
It can cost millions for your business if you oversee these QA Testing Services for the digital firm. Imagine, if you are an owner of a health organization, and your EHR system is showing an error. It does risk a patient's life. While an eCommerce website that has performance issues might cost the owner his overall profit generation. The Software Testing Service market size was at USD 40 billion in 2020, estimated to grow at a CAGR of 7% from 2021 to 2027.
Now, without doing further due, let's get into the regression QA Testing Services. This quality assurance comes as a priority when there are constant changes from the developers. While developing a website or application, developers might need to do changes in their code or integrate a new feature. Unknowingly, after changes are made, the software may not work as before. There are several system crashes or collapses.
The main aim of regression testing services is to discover the errors that accidentally occurred during:-
Upgrading the system
Fix a particular bug
Adding at least one feature
What Is Regression Testing?
It is a black-box testing technique that is used to authenticate a code change in the software. The test takes place without impacting the existing functionality of the product. It only tests the external factors responsible for software failure.
The Software Testing Service helps in getting rid of the risk that is linked with updated websites, and applications.
It is performed by a QA team after the development team has completed their part of the work.
It is also known as a verification method.
At The Custom Websites, we ensure an impeccable customer experience by providing excellent Software Testing Service. Our QA engineers have vast experience in testing & data validation.
Why Do Our Qa Analysts Perform Regression Testing?
Regression testing takes place when the code is modified. The following are the scenario for performing regression testing:
1. When New Functionalities Are Added
For instance, the website or application has login functionality, which allows users to log in with their email ID. Now, the developer has integrated a new feature to log in with a phone number, which needs to be tested for the best user experience.
2. When There Is Any Change In The Existing Requirement
For example, remove the "Remember Password" button, which was present before.
3. When There Is A Defect That Needs A Quick Fix
In case the sign-up button does not work, then a bug is generated by the tester. The developers fix it. Once the bug gets fixed, the tester verifies the sign-up button's working condition. Similarly, the tester also tests other functionality, which is related to the sign-up.
4. When The Performance Issue Is Solved
For instance, reducing the loading time of any page.
Types Of Regression Testing
Unit Regression Testing
It should be taken up in the initial unit testing phase, which tests the code as a single unit.
Partial Regression testing
It is performed when making slide changes to the code. This testing process ensures to make the system works properly even after adding new code or when even slight code changes are made.
Complete Regression Testing
Involves testing the changed units as well as any old features of the application. It was commonly taken up to test when more than one code changed. This testing has to be performed before any major release or product delivery to ensure all functionalities continue to work seamlessly.
Build Level Regression Testing
This method of regression testing at the building level corresponds to testing during the second build of the upcoming release and is usually taken up when some code changes are done across the builds.
Benefits Of QA Testing Services
It helps to make sure that any changes like bug fixes or added new features included in the module have no impact on the existing code.
It helps in improving the quality of the product.
At the time of regression testing, test cases are a priority depending on the changes done to the existing feature. And then, the module has taken priority testing.
