What is the difference between ‘integration testing’ and ‘system testing’? Knowledge in 3 minutes

Integration testing and system testing are part of the software testing process in the case of V-model development.

Integration testing is testing that combines software modules and verifies that they work as a system. System testing is testing an entire system of software to verify that it works in accordance with requirements definitions.

Difference between Integration Testing and System Testing

The difference between integration testing and system testing is as follows

• Scope: Integration testing is testing that combines software modules and verifies that they work as a system. System testing is testing of an entire software system to verify that it works in accordance with requirements definitions.
• Test Objectives: Integration testing combines software modules. System testing tests an entire system of software.
• Testing Methodology: Integration testing involves testing the coupling between modules and the interface between modules. System testing involves testing the operation of the entire software system and conformance to requirement definitions.

Integration testing and system testing are important testing processes to improve software quality.

Integration testing verifies the coupling between software modules to detect software defects at an early stage. System testing verifies the behavior of the software according to the software requirements definition by testing the entire software system.
