What is the difference between System Testing and Integration Testing in QA Testing?

In QA Testing, System Testing and Integration Testing are two crucial phases. While both are aimed at ensuring the software's quality, they serve different purposes.

System Testing:

System Testing involves testing the whole software system as a complete and integrated application. It verifies that the entire system meets specified requirements and functions correctly as a whole.

Integration Testing:

Integration Testing focuses on testing the interactions between software modules or components to ensure they work together as expected. It validates the interfaces and interactions between integrated units.

Key Differences:

• System Testing tests the entire system, while Integration Testing focuses on the interactions between modules.
• System Testing is performed after Integration Testing and validates the software as a whole.
• Integration Testing is typically performed before System Testing and focuses on the connections between components.

Overall, System Testing verifies the entire software system, while Integration Testing checks the interactions between components.
