Regression testing vs. UAT: Know the difference?

 

Regression testing and User Acceptance Testing (UAT) play a key role in developing a quality product. Regression testing ensures that the functionality of the software product or application is working as per the expected requirements, despite changes being made in the code. 

User Acceptance Testing is involved in ascertaining whether the product meets business and user-specific requirements. In this article, you will get to know what are the differences between regression testing and user acceptance testing.

What is Regression testing Definition?

It is a testing method that verifies the new changes made to the code do not alter or modify the existing functionalities. This testing method makes sure that the existing functionalities do not get altered or modified, despite changes being introduced in the code. 

Whenever a code change happens during the software application development process, regression testing is performed. This testing method checks the overall functionality and stability of the existing features.  

The changes that are made in the code may involve malfunctions, defects and dependencies. These risks are mitigated through the regression testing method and also make sure that the previously developed and tested code is operational, despite making new changes. 

Through this testing method, product teams can receive crucial feedback and respond instantly. Bugs are detected early on in the software development process. Built-up defects can be resolved by not investing much in cost and maintenance efforts.                

 

What is User Acceptance Testing (UAT)?

UAT Meaning: It is the final phase of testing in the software development process. It is performed just before the software product or application is going to be released. 

In this testing method, end-users are given the responsibility to test the product with the help of the testing and development team and other specific resources. The end-users need to thoroughly test the product from a usability, functionality and performance standpoint.

Post testing the product, the user’s feedback is obtained and is considered to be crucial for the team. Based on the feedback provided, necessary decisions are taken by the team in order to further modify the product. 

The end-to-end business flow is validated and ensures that the software product or application is built as per the user and business specific requirements. The software is validated against the business requirements using this testing method. In certain scenarios, it is also known as beta testing or end-user testing.

Differences between regression testing and user acceptance testing:

Regression testing	User Acceptance Testing
In this testing method, the code changes that have been made are verified and made sure that it does not affect the existing functionalities	This testing method is carried out when the software is fully developed to determine Its value in terms of usability and functionality from a user’s standpoint
Regression testing checks whether any new errors/defects are generated due to the previous errors/defects that have already been fixed	An end-user will check whether the proposed system is in line with the desired business requirements
The Testing and development team perform this testing method	End-users/customers/stakeholders perform this testing method
The functionality of the modules is checked	The acceptance and user-friendliness of the product are checked
It is carried throughout the development lifecycle, whenever new features are added or updates are introduced. Even if there are changes being made in the code, regression testing is performed	This testing method is carried out at the final stage of the software development process, just before the product’s release.
