5G is being rolled out globally, transforming mobile networks. As technologies like edge computing, network slicing, and IoT become mainstream, testing and validation must also evolve to meet modern network demands. Conventional frameworks cannot respond to the increasing complexity, heterogeneity, and scalability demands imposed by modern communication ecosystems. This review shows current limitations and discusses advanced test architecture whilst proposing a theoretical architecture combining multi-layer artefacts with AI, digital twins, and cross-domain orchestration. Also, the paper states that regulatory harmonization, adaptive test automation, and cybersecurity compliance requirements are currently integral to operating at a global scale and helping to facilitate interoperability for organizations. With the continual emergence of new standards aimed at enhancing policy compliance, there is an increasing emphasis on the development of intelligent, scalable, and policy-compliant certification ecosystems. Overall, the review gives an extensive perspective on how network validation should be optimized for the emerging 5G and beyond environment.
