User Acceptance Testing (UAT) is the final stage in the software development lifecycle, crucial for validating that the application meets the needs of users and clients. It involves end-users testing the application to identify any remaining bugs and ensure quality before production. UAT can include various types such as alpha testing, beta testing, contract acceptance testing, business acceptance testing, and regulation acceptance testing, all aimed at ensuring compliance and functionality.

1. In the software testing practice, there are several stages such as unit testing, integration
system, system testing, and user acceptance testing (UAT). Among these, the last stage of
testing is having a very special importance in Software Development Lifecycle (SDLC), as it
helps to validate whether the developed application is as per the needs of both users and
clients.
This way of practicing UAT helps the teams to identify whether the previous stages of
development and testing have been on the right track or not. Also, by validating, it prevents
enterprises in delivering software that is not quality-assured. Hence, it is essential to
practice UAT testing before planning to move the software for production.
As mentioned in the term UAT, the testing practice effectively helps to validate whether the
developed application has the ability to work for the users or not. Also, UAT testing helps to
check if the application as per the conditions mentioned by the clients, helps to identify and
fix the leftover bugs. Thus, UAT testing helps enterprises in moving quality-assured software
for production.
UAT is practiced after system testing and before moving the application for production. In
this testing practice, end-users or clients perform the test to validate the application. The
testing is performed by considering the perspective of the end-user and the requirements.
In Alpha testing, a team of testers performs testing in the test environment or the
development environment. The feedback that is received from these alpha testers helps in
fixing the bugs and improving the usability of the product.
Whereas, in Beta testing, the software is exposed to real-end users. These beta testers or the
beta users assess the application and the continuous feedback received from them helps in
maintaining good user experience and enhance the quality of the software.

WHAT IS UAT TESTING?
5 TYPES OF UAT TESTING
5 TYPES OF
UAT TESTING
Alpha and
Beta Testing01
In this UAT testing type, the testing teams analyze the functionalities of the application
without knowing the internal code structure. By performing black-box testing, it helps the
teams in validating whether the developed application is meeting the requirements or not.
Black-box
Testing
With this UAT testing type, the testing teams are able to validate whether the developed
application can meet the specifications and criteria that were discussed earlier during the
contract.
Contract
Acceptance
Testing (CAT)

03
In this UAT testing type, the teams perform testing to validate whether the developed
application is able to meet the specification or the criteria or the standards that are set by the
enterprise.
Business
Acceptance
Testing (BAT)
04
This type of testing is also known as Compliance Acceptance Testing and here, the testing is
performed to validate if the developed application can meet the standards and the
regulations that are set by the government agencies.

UAT is one of the very important phases in SDLC, and it is practiced at the end before
planning to send the application for production. By performing UAT testing with the help of
end-users, enterprises are able to validate if the application is able to meet the required
functionality, identifies and resolves the leftover bugs, etc. The above-mentioned information
is about the 5 important types of UAT testing types. Leverage UAT testing services from
leading QA services provider to deliver a quality-assured application for your users.
