Purpose: System integration testing aims to ensure that the entire integrated system meets a set of requirements. It is performed in an integrated hardware and software environment to validate the system's proper functioning as a whole.
System integration testing verifies that the various components of the system work together seamlessly, ensuring proper data flow, communication, and interoperability. It aims to identify any issues or defects that may arise from the integration of different components and to ensure that the system functions as intended.
However, it is important to note that the use of system integration testing should be limited. This is because it requires a fully functional end-to-end environment with all components set up and configured simultaneously, which can be resource-intensive and expensive. Therefore, system integration testing is typically conducted selectively, focusing on critical aspects of the system that require validation in the integrated environment.
By performing system integration testing, testers can ensure that the integrated system functions properly and meets the defined requirements before it is released to production. It helps identify any issues or inconsistencies that may arise from the integration process and enables teams to address them before the system is deployed to end-users.
When:
- System Integration Testing (SIT) is conducted on demand, prior to release, as needed. It is typically performed when the integrated system is ready for testing in an integrated hardware and software environment.
Tools/Technology:
- UTAF (Unified Test Automation Framework): A framework that provides a unified approach to automate system integration testing across different components and technologies.
- qTest: A test management tool that helps manage and track system integration test cases, defects, and overall testing progress.
