13.6Interview Talking Point

"Agentic testing architectures solve a specific problem: testing scenarios where the state space is too large or too dynamic for scripted tests. I think about it in three patterns. The Orchestrator splits testing by domain -- UI, API, security -- with a coordinator that merges results. The Swarm runs independent agents in parallel for maximum coverage breadth, then reconciles duplicates. The Critic-Actor uses adversarial review to catch hallucinated assertions and weak tests before they ship. The critical design principle is guardrails: max steps, token budgets, domain allowlists, and wall-clock timeouts. Without constraints, agents are expensive and non-deterministic. With proper harnesses, they become powerful exploratory testing tools that complement -- but never replace -- deterministic regression suites in CI. The OpenObserve case study is the best real-world validation I have seen: eight specialized agents grew a Rust test suite from 380 to 700+ tests while reducing flakiness by 85%, because the agents could run each test five times to detect non-determinism that humans were ignoring."
