Copilot Studio agents don’t fail like traditional software. A small change to knowledge, instructions, actions, or security settings can quietly shift behavior, and you won’t notice until a user hits the worst possible edge case in production.

This session provides a practical testing strategy for Copilot Studio agents, based on Microsoft guidance and real-world patterns. You’ll learn how to “shift left” and treat testing as a continuous process: validate core scenarios, test knowledge coverage, run performance testing, regression suites before every release, and perform adversarial testing to catch prompt tricks, ambiguous intent, and unsafe action paths. We’ll also explore test sets and agent evaluations in Copilot Studio. You’ll learn how to use evaluation methods to measure what matters and how to turn those results into an iteration loop.
