What Is Regression Testing And What Does It Entail?

Intro

Regression testing is a type of test which is done to ensure that after any changes are made to the software, the previous functionality of the product remains intact.The process of regression testing can be complicated, and it’s often difficult for software developers to know exactly how to perform it. This is to ensure that the product works as expected and does not have any bugs. Software engineers will perform regression testing after every code change or new feature implementation. The goal of this process is to avoid unexpected side effects within the software, which could lead to an unpleasant user experience.. In this article, you will find out what is regression testing and what does it entail?

What Is Regression Testing And What Does It Entail?

What is Regression Testing?

Regression testing is a type of testing that is used to verify that a software application still works after it has been changed or updated. This type of testing is important because it helps ensure that the software application continues to work as expected after any changes are made to it. 

There are many different ways to perform regression testing, but one common method is to create a test suite of tests that cover all of the functionality of the software application. This test suite can then be run each time a change is made to the software to ensure that all of the features still work as expected. 

Another common method for performing regression testing is to use automation tools to run the tests. This can be especially helpful if there are a large number of tests or if the tests need to be run frequently. Automation can help make regression testing more efficient and effective. 

Overall, regression testing is an important part of the software development process that can help ensure that changes to a software application do not break existing functionality. By using regression testing, organizations can avoid potential issues and keep their software applications running smoothly.

What does Regression Testing entail?

Regression Testing is the process of retesting a software application after changes have been made to it. This is done to ensure that the changes haven’t caused any new bugs or issues. It’s an important part of the software development process, as it helps to ensure that new changes haven’t introduced any new problems. 

There are many different approaches to Regression Testing, but one common approach is to create a regression test suite. This is a collection of tests that cover the functionality of the software. These tests are run every time a change is made, and if any of them fail, this indicates that there may be a problem with the change that was made. 

Another approach is to use regression testing tools. These tools can automate the process of running regression tests, which can save time and effort. However, they can also be expensive, and may not be suitable for all projects. 

Whatever approach is used, Regression Testing is an important part of the software development process, and can help to ensure that changes don’t introduce new bugs or issues.

What are the types of Regression Tests?

There are four main types of regression tests: functional, interface, regression acceptance, and unit. 

Functional regression testing is the process of verifying that the functionality of a system works as expected. This type of test can be performed manually or with automated testing tools. 

Interface regression testing is the process of verifying that the interface between two systems works as expected. This type of test can be performed manually or with automated testing tools. 

Regression acceptance testing is the process of verifying that a system meets the acceptance criteria for a given release. This type of test is usually performed manually. 

Unit regression testing is the process of verifying that a unit of code works as expected. This type of test is usually performed automatically using a unit testing framework.

When do you perform a Regression Test?

A regression test is a type of testing that is used to find out if a software application has regressed, or deteriorated, in functionality from a previous build. In other words, it is used to ensure that any new changes made to the code haven’t caused any bugs or issues.

There is no set time or frequency for when regression tests should be carried out, as it will depend on the individual software application and how often it is updated. However, it is generally advisable to perform a regression test after any major changes or updates have been made.

Conclusion

Regression testing is an important process that helps ensure the quality of software products. By retesting functionality that was previously working correctly, regression testing can help identify new defects that have been introduced as a result of changes made to the code. While it can be time-consuming, regression testing is essential for ensuring that software changes don’t break existing functionality and for maintaining the overall quality of the product.
