A Hands-On Guide to Testing Agents with RAGAs and G-Eval

# Plain-English Summary If you're using AI systems that search through documents to answer questions (a common business tool), you need reliable ways to check whether those systems are actually giving you correct answers—and new testing methods like RAGAs and G-Eval make that job easier and more affordable than building custom tests yourself. Think of these tools as automated quality checkers that evaluate whether your AI assistant is pulling the right information and presenting it accurately, helping you catch problems before customers do. This matters because as more companies deploy these AI systems for customer service, research, or internal knowledge management, having confidence in their accuracy becomes a competitive advantage.
