Security scanning in functional testing involves systematically scanning the software to discover security vulnerabilities. This process is crucial for identifying and addressing potential threats, ensuring that the system is robust and resistant to security breaches.

Penetration testing is a security testing technique that involves simulating real-world attacks on a system to identify vulnerabilities and assess its ability to withstand malicious activities. It helps in uncovering potential weaknesses that could be exploited by attackers.

The primary focus of performance considerations in functional testing is assessing the software's responsiveness. This involves evaluating how well the application performs under varying conditions, such as different loads or concurrent users, to ensure optimal user experience and system reliability.

Monitoring test execution progress is crucial for a project manager to ensure that testing activities align with the project timeline. Other key metrics such as defect density, test coverage, and test case pass rate provide insights into the quality and completeness of testing. These metrics collectively help the project manager assess the overall effectiveness of the testing process and address any issues promptly to ensure a successful software development project.

Performance considerations in functional testing are often addressed during the Testing Phase of the Software Development Life Cycle (SDLC). This phase is crucial for evaluating how well the software performs under different scenarios before it is deployed for actual use.

In pairwise testing, the selection of parameters is crucial for achieving comprehensive coverage. By carefully choosing input combinations, this testing method aims to cover a wide range of scenarios while minimizing the number of test cases, making the testing process more efficient and effective.

A high-severity defect has a significant impact on the system. Low-performance response time can adversely affect the user experience, making it an example of a defect with high severity.

The severity of a defect is crucial when prioritizing, as it reflects the impact on the system. High-severity defects often take precedence over lower-severity ones for timely resolution.

Non-functional testing concentrates on the performance, security, and reliability aspects of the system, rather than its specific functions. Performance testing is a key part of non-functional testing.

The Breakpoint feature in TestComplete is crucial for debugging and troubleshooting automated tests. It allows testers to pause the test execution at a specific point, inspect variables, and step through the code. Breakpoints are instrumental in identifying and resolving issues, ensuring the reliability of automated tests and helping testers understand the flow of test execution.
