ABSTRACT

The evolution in technology has helped to give a boost to the technological aspect of software testing . Today, many companies and professions are inclining towards digitalization and other forms of new software trends and technologies to match the standards of the market .

Digitalization is proven to be a way of specialized software testing that covers the entire gamut of software testing methods . After an initial setback of a few months that happened in 2020 regarding the COVID-19 pandemic , many companies faced many challenges .

What is regression testing is all about?

Regression testing is defined as a testing method where existing software applications and it is one kind of testing where tests are rerun so that the application has minimal risks. What is a business without challenges? It's nothing.

Challenges are a proven way to improve the quality of the services and improve the company's reputation. With the help of regression testing, companies have to go through several hurdles.

Regression testing aims at performing continuous testing as it helps in improving the overall quality and gives stability to the software.

Regression testing is also one of the significant factors for gaining customer confidence and helps the team identify defects and eliminate them as soon as possible.

It verifies the functionality and the working of an application because of the newly added features to gain stability.

Why we need Regression Testing?

Regression testing is an incremental validation technique for testing a product. It is used to authenticate code changes in software, not to impact the existing functionality.

It is a black-box testing technique that is reexecuted to check the previous functionality of the app when new changes are made.

Since regression testing starts at a very early period of the product development cycle, it helps decrease the probability of hidden requirements.

REGRESSION TESTING BENEFITS The best part about regression testing is that it uses AI-driven technology and virtual reality intelligence techniques for testing procedures.

These technologies help give correct and accurate results for the functioning of the software.

Regression testing also ensures a bug-free application and a smoother integration between the modules in an application. It also helps avoid any discrepancies by providing support in terms of testing releases.

Regression testing also reduces unnecessary expenses, and the overall cost is also minimized by using automated software testing solutions.

Regression testing also outweighs the risks of skipping it and detecting and fixing the bugs in software before it is shipped into the market.

It also helps provide a top-quality product as it understands the core functionality that is tested.

Regression testing substantially increases in the testing process through automation scripts. It also helps in generating customer faith through higher CSI.

Regression testing should occur in different scenarios based on every day and platform to prevent issues from reaching the user.

Before the regression testing takes place, fixes start ruling to ensure that the exiting sunshine is not buying any new feature.

The DevOps team should be ready when the regression testing happens to ensure that the additional features work with the existing ones very smoothly.

Regression testing also involves fixing bugs and performing some cold modifications to prevent the court from getting affected.

It also eventually distributes the operational system and works where the post defect retesting is to occur.

Regression testing in a jail occurs when the situation is checked in terms of services. It is done to ensure that the modification does not cause any damage to the rest of the functionality.

It is also performed when the application crashes, which causes a problem in the performance issues.

It also occurs when the code is migrated on an advanced platform through a fixed developer so that the critical bugs can be identified and solved.

It also involves patching activity which is carried out after the testing procedure.

THE TYPES OF REGRESSION TESTING Corrective regression testing is a procedure that involves performance testing that is appreciated for its simplicity as it requires comparatively lesser effort. It is a method where existing test cases are used in the product specifications that have been made. It is a corrective way of doing the regression procedure and methods.

Retest- all regression testing - A complex testing approach means every system component is tested right from scratch. It is a more retrospective method in nature as it is approached when suspicion arises during the previous testing stages. Under such circumstances, this type of testing becomes very important as it helps identify what went wrong.

It also emphasizes the budget concerns giving more quality reassurance about the system's current state.

Advanced regression testing - Is an approach that establishes test cases when the new ones get created. It is often a case with set product specifications that helps in addressing the changing requirements. It involves using new techniques when the product vision is affected.

Complete regression testing is an agile approach that many companies adopt to encourage doing lesser but frequent updates. It is not always possible for companies to react quickly to the ever-changing kind months, but it can help them in large-scale system updates when complete regression testing is performed.

Unit regression testing - This type of testing has a more straightforward approach, for it is focused on testing code as a single and a separate unit. It was also based on dependencies, integration, and interactions depending upon the scope.
