UAT and SIT are the two different levels of testing in the application testing phase of QA. UAT stands for User Acceptance Testing and SIT stand for System Integration Testing. Here we compare UAT vs. SIT against one another.

UAT: User Acceptance Testing Best Practices
User Acceptance Testing is the final stage of testing before the system is accepted by the operational user. End users perform UAT based on the user requirements specifications to confirm whether an application is meeting requirements.
Types of UAT:
There are two major types of User Acceptance Testing: Alpha Testing and Beta Testing.
Alpha Testing: Alpha testing is performed at the developer’s site by the customer. The testing is performed under a developer’s control. Alpha Testing is performed once the system testing is completed.Beta Testing: Beta testing is performed at one or more customer’s sites by the end user of the software. For the beta testing of an application, it is given to a trusted customer. Here the testing is not under developer’s control. Beta testing is performed only after alpha testing is done.
SIT: System Integration Testing Best Practices
System Integration Testing is performed to confirm whether the modules tested individually can work together to deliver the required functionality. Modules tested individually may work fine, but when they are integrated together some issues may occur. System integration testing is performed to test the dependency between modules through transfer of data from one module to another.
System integration starts at the module level where units are integrated together forming to form a subsystem and eventually a system.
Types of SIT:
There are two major approaches to System Integration Testing: top-down integration approach and bottom-up integration approach.
Top-down Integration Approach: Here modules are integrated by moving downwards in hierarchy, where the main module is at the top. In a top-down approach if lower modules are not ready a dummy modules called a stub is used for testing. A stub acts as the module during the test. Stubs have the minimum functionality required to be used while testing the ‘above’ module.Bottom-up Integration Approach: Here modules are combined and started to test at very low level. If the top level modules are not ready then drivers are used for testing. A driver is a program specially used for testing.
Comparison between UAT vs. SIT:
|No.||SIT- System Integration Testing||UAT- User Acceptance Testing|
|1||Testing interface between modules||Testing with respect to user requirements|
|2||Purpose of testing is to see the interface||Purpose is to test the functionality from end user’s point of view.|
|3||Performed by Developers and Testers.||Performed by Customers and End Users.|
|4||Issues will be with data flow, control flow.||Not as per User Requirements.|
