System Testing Vs Integration Testing

System testing and integration testing are important levels of software testing used to ensure software quality. They verify that different software components work correctly both individually and as a complete system. These testing types help deliver a reliable and stable application.

Integration testing verifies communication between modules.
System testing validates the complete application.
Both help identify defects in the software.

System Testing

System Testing is a type of software testing in which the entire integrated application is tested as a complete system to verify that it meets functional and non-functional requirements. It is performed after integration testing and before acceptance testing.

Example: In an e-commerce website, system testing verifies the complete flow such as login, product search, add to cart, payment, order confirmation, and notifications.

Integration Testing

Integration Testing is a type of software testing in which individual modules are combined and tested together to verify their interaction. It is performed after unit testing and before system testing.

Example: In an e-commerce application, integration testing verifies that product, cart, order, and payment modules work together correctly with proper data flow and payment confirmation.
