Your Agent Tests Are Wrong (How Production Teams Actually Test Agents)

Your agent tests are probably useless.

Not because testing agents is impossible. But because you're testing the wrong things.

The Problem:

• LLM outputs are non-deterministic
• Tool calls vary
• Conversation flows are dynamic
• Traditional assert response == "expected" fails constantly

The Solution: 3-Layer Testing Framework

Layer 1: Unit Testing Test tool functions, not the agent

• API calls work correctly
• Error handling triggers
• Input validation passes
• Deterministic behavior

Layer 2: Integration Testing Test agent decisions with eval datasets

• Right tool selected?
• Parameters correct?
• Outcome achieved?
• 90%+ pass rate required

Layer 3: Production Testing Test outcomes with real usage

• Task success rate >90%
• User satisfaction monitoring
• Cost per request tracking
• Real-time alerts
