The Citcom.AI RISE testing approach is a step towards structured AI system evaluation and testing under the AI Act's regulatory framework. It establishes a definition of context in the scenario of different AI application domains, AI subfields, and use cases. In particular, a systematic evaluation, from defining the context and application to detailed risk assessments, linking each AI application to corresponding testing standards and methodologies, is presented. The approach translates AI Act’s high level regulatory requirements for different AI system risk levels to appropriate technical testing techniques for achieving trustworthiness across different domains and AI subfields, promoting responsible AI deployment and fostering trust in AI applications.
