Production Test Harness Implementation
9.1From Guardrails to a Complete HarnessThe five guardrails define the boundaries. The production harness is the complete implementation that enforces them while providing a clean…9.2The ConstrainedTestHarness Class9.3Running Multiple Tests with the HarnessIn practice, you run many tests through the same harness. Each test gets its own step/token counters but shares the harness configuration.9.4Harness ObservabilityA production harness must be observable. Every action, decision, and guardrail check should be logged.9.5Harness Patterns for Different Test Types9.6Error Recovery in the HarnessThe harness should handle agent failures gracefully:9.7Key TakeawayThe production harness is the bridge between the abstract guardrail concepts and a working system.
