Debugging And Testing Questions
System testing and integration testing are both important phases in the software development life cycle, but they serve different purposes and focus on different aspects of the software.
System testing is a level of testing that evaluates the complete and integrated system to ensure that it meets the specified requirements. It is performed on a fully developed and integrated system to validate its functionality, performance, reliability, and other non-functional aspects. System testing is typically conducted by independent testers who are not involved in the development process.
On the other hand, integration testing is a level of testing that focuses on testing the interaction between different components or modules of the system. It aims to identify defects in the interfaces and interactions between these components. Integration testing is performed after unit testing and before system testing. It ensures that the individual components work together as expected and that the system functions as a whole.
In summary, the main difference between system testing and integration testing lies in their scope and focus. System testing evaluates the entire system, while integration testing focuses on the interaction between components.
