Software Testing And Quality Assurance Questions
System testing and integration testing are both important phases in the software testing process, but they differ in their scope and objectives.
System testing is conducted to evaluate the overall functionality and performance of the entire system or software application. It is performed after the completion of integration testing and focuses on verifying that the system meets the specified requirements and functions as expected. System testing is typically black-box testing, where the internal structure and design of the system are not considered. It aims to identify any defects or issues that may arise when different components of the system interact with each other.
On the other hand, integration testing is performed to test the interaction between different modules or components of the system. It ensures that the individual components, which have already been tested, work together as intended and that data flows correctly between them. Integration testing can be both black-box and white-box testing, depending on the level of knowledge about the internal structure of the system. It helps to identify any defects or inconsistencies that may occur during the integration process.
In summary, the main difference between system testing and integration testing lies in their scope. System testing evaluates the overall system functionality, while integration testing focuses on the interaction between individual components.
