Following are the differences between user acceptance testing and system testing:
User acceptance testing:
- This testing method verifies whether the software product or application is able to meet the customer's requirements or not. The acceptance criteria are basically covered and provided by the client before product development
- This testing method is performed by stakeholders, users, testers as well as clients
- It is performed after system testing.
System testing:
- This testing method carries out the assessment of product functionality. This testing method covers both the functional as well as behavioral aspects of testing as per the document specifications
- This testing method is performed by both testers as well as developers
- It is performed after development and before product delivery.
Following are the differences between User Acceptance Testing (UAT) and System Integration Testing (SIT):
User acceptance testing:
- Testing is performed by taking users into consideration, who will be responsible to test the product in a real-time environment and provide their valuable feedback
- The functionality is tested from the end user's point of view
- End-users, stakeholders, customers etc., will be conducting user acceptance testing.
System Integration testing:
- The interface between modules is tested using this testing method
- SIT is conducted to understand and analyze the interface
- It is performed by both testers and developers
Following are the differences between User Acceptance Testing and Usability testing:
User acceptance testing:
- This testing method assesses and verifies whether the software product or application meets the user specific requirements or not
- This testing method ensures that the software product or application is aligned with the business requirements
- It is performed at the final stages of the software development process
Usability testing:
- The efficiency and ease of use of the software product or application is evaluated. This includes its navigation, interface and user interface elements
- Usability issues are identified and the user experience and software's design are enhanced
- It is generally carried out at almost all the stages of software development.
