Reliability testing is aimed at verifying the software's ability to function under expected conditions for a specified period of time. It is typically conducted during system testing, where the software is tested in its entirety to ensure that all components work together as expected in an environment that closely simulates the production environment. Reliability testing is not typically associated with static testing, component testing, or functional acceptance testing, as these levels of testing do not address the overall behavior of the system over time.

To address the product risk of requiring an availability of almost 100%, the quality characteristic of reliability should be part of the test approach. Reliability testing focuses on the ability of the system to perform under expected conditions for a specified period of time. It is essential for systems that need to be operational continuously or near-continuously. This characteristic encompasses the system's uptime, fault tolerance, recoverability, and the ability to perform under anticipated conditions, all of which are relevant to maintaining high availability.
