How to Perform System Integration Testing?

- #1) Data state within the Integration Layer.
- #2) Data state within the Database layer.
- #3) Data state within the Application layer.
- The image below on the levels of testing would make the flow from Unit testing to UAT clear to you:
What is SIT environment in testing?
System integration testing (SIT) is a high-level software testing process in which testers verify that all related systems maintain data integrity and can operate in coordination with other systems in the same environment.
What is difference between SIT and UAT testing?
System integration testing is done mainly to test the interface requirements of a system. Whereas user acceptance testing is done to verify the system functionality as a whole by an end-user. Appropriate test cases have to be written for both the testing.
What are the 5 levels of testing?

Details of different Levels of Testing:
- Unit/component testing. The most basic type of testing is unit, or component, testing.
- Integration testing. Integration testing aims to test different parts of the system in combination in order to assess if they work correctly together.
- System testing.
- Acceptance testing.
- Conclusion.
Who performs SIT testing?
Testers
Comparison between UAT vs. SIT:
No. | SIT- System Integration Testing | UAT- User Acceptance Testing |
---|---|---|
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. |
What is the purpose of SIT?
System Integration Testing (SIT) is performed to verify the interactions between the modules of a software system. It deals with the verification of the high and low-level software requirements specified in the Software Requirements Specification/Data and the Software Design Document.

Is SIT functional testing?
The testing performed on the absolute integrated products to check system compliance with specified requirements on functional and non-functional elements is referred to as system testing. SIT is also considered as a combination of integration testing and system testing.
Why is the sit and reach test important?
The sit and reach test is a common measure of flexibility, and specifically measures the flexibility of the lower back and hamstring muscles. This test is important as because tightness in this area is implicated in lumbar lordosis, forward pelvic tilt and lower back pain.
What is adhoc testing example?
Performing random testing without any plan is known as Ad Hoc Testing. It is also referred to as Random Testing or Monkey Testing. This type of testing doesn’t follow any documentation or plan to perform this activity.
