Debugging And Testing Questions
Functional testing and system testing are both important aspects of the software testing process, but they differ in their scope and objectives.
Functional testing focuses on verifying that individual functions or features of a software application are working correctly. It involves testing each function or feature in isolation to ensure that it performs as intended and meets the specified requirements. Functional testing is typically performed by testers and may involve techniques such as unit testing, integration testing, and regression testing.
On the other hand, system testing is a broader level of testing that evaluates the entire system as a whole. It aims to validate the system's compliance with the overall requirements and specifications. System testing involves testing the interactions between different components, subsystems, and modules to ensure that they work together seamlessly. It may include tests such as performance testing, security testing, and usability testing.
In summary, the main difference between functional testing and system testing lies in their scope. Functional testing focuses on individual functions or features, while system testing evaluates the system as a whole, including its interactions and overall compliance with requirements.
