True or False: The only time you need to test a system is at the completion of the installation.

Testing a system only upon completion of the installation is insufficient for ensuring reliability and proper operation. Continuous testing throughout the different stages of installation and even after it is essential for several reasons.

First, conducting tests after each component installation allows for immediate identification of any issues that may arise, ensuring that each part is functioning correctly before the entire system is connected and operational. It helps to isolate problems quickly and provides an opportunity to rectify them on the spot.

Second, regular testing and checks after installation, such as routine maintenance assessments, ensure that the system continues to function as intended over time. External factors, software updates, and other changes can affect system performance, so ongoing testing is crucial.

Lastly, in cases where issues arise, proactive monitoring and testing can prevent further complications and help maintain a secure and efficient system for users. Thus, the assertion that the only time testing is required is at installation completion is misleading, as comprehensive testing practices are necessary for both initial setups and ongoing system assurance.
