What is the main purpose of a System Integration Testing (SIT) environment?

The primary purpose of a System Integration Testing (SIT) environment is to conduct system-to-system testing. This phase of software testing focuses on verifying that various independently developed components of a system work together as intended. During SIT, different modules or systems are integrated, and the interactions between them are tested to ensure that data is correctly exchanged and that the overall system performs as expected.

This type of testing is crucial in identifying issues that may arise from the interaction between integrated components, which might not be apparent when testing them in isolation. The goal is to validate the end-to-end functionality and interactions before the system is moved to production, allowing for the resolution of any issues beforehand.

Having a dedicated environment for this purpose minimizes the risk of disrupting production systems, ensuring that comprehensive testing can be executed with the necessary configurations and resources needed for effective integration validation.
