The human oversight interface is a compliance-critical component that requires dedicated unit tests. The mandatory review workflow must not be bypassable: tests confirm that there is no API endpoint, configuration flag, or administrative override that allows system outputs to be applied without human review. Override functionality must work correctly, and the rationale capture must record the required information.

Confidence indicator tests verify that the confidence score displayed to the operator matches the model’s actual output confidence, and that the visual representation (colour coding, gauge, or equivalent) accurately reflects the configured thresholds. Automation bias countermeasure tests verify that the data-first display pattern works correctly (case data shown before the model’s recommendation), that the minimum dwell time enforcement functions as configured, and that calibration cases are injected at the specified rate.

These tests should run on every interface change and on a periodic schedule to catch regressions. For high-risk systems, the bypass prevention tests are critical failures: any test path that allows auto-acceptance of the model’s recommendation without human review is a compliance gap that blocks deployment.

Key outputs

• Bypass prevention tests confirming no auto-acceptance pathway exists
• Override and rationale capture functional tests
• Confidence indicator accuracy tests
• Automation bias countermeasure verification tests
