System integration testing

System Integration testing is actually a well-known testing level and falls under integration testing, which we have already covered in the previous responses. So, I will not repeat the same information again.

Regarding other miscellaneous testing levels, here are some additional details on System Integration Testing.

System Integration Testing: System Integration Testing is a type of testing that verifies that the different modules or systems integrated together can work together as expected. The goal of system integration testing is to verify that the integrated system is meeting the business requirements and is ready for deployment.

System integration testing focuses on testing the interfaces between the different systems or modules, the data flow between them, and the functionality of the system as a whole. In this testing, different modules or systems are integrated to form the overall system, and the testing team verifies that the system is functioning as expected.

System integration testing also involves testing third-party systems or components that are integrated into the system, such as APIs, web services, databases, etc. The testing team verifies that these third-party components are working as expected and are integrated correctly with the system.
