N2 - Radio Access Networks (RANs) are increasingly softwarized and disaggregated, resulting in diverse and interoperable components running on commodity hardware and compute platforms. This heterogeneous paradigm demands principled and comprehensive testing to ensure high performance and efficiency in RAN deployments. In this paper, we present a real-time RAN testing framework, called ETHOS, designed to capture fine-grained metrics on performance, energy consumption, and computational efficiency for O-RAN-compliant systems across a range of compute platforms. ETHOS leverages a shared memory-based inter-process communication (IPC) framework and automates testing through the emulation of diverse user traffic and channel conditions. We deploy ETHOS on the NVIDIA ARC-OTA platform and demonstrate its effectiveness through a detailed case study evaluating RAN components under varying scenarios. We also present a comparative study versus the srsRAN for the cross-platform observation. ETHOS is designed to be easily portable to other commercial and open-source RAN software, offering the potential for a unified testing and evaluation framework to accelerate O-RAN research and innovation.
