Testing & Quality
What is System Integration Testing (SIT)?
Testing end-to-end processes across modules, interfaces, and systems to confirm they work together.
SIT runs E2E scenarios with interfaces, batch jobs, outputs, and role-based users where possible. It is typically executed in multiple cycles by the project team. Most cross-module and interface defects are found here.
