The model serving component requires unit tests confirming five properties. The model must load correctly from the model registry using the registry client. Inference must produce outputs in the expected format and range. For deterministic architectures, inference must be deterministic for a given model version and input.

The model’s latency must fall within the documented Service Level Agreement. A test that submits a representative input and measures the inference duration confirms that the serving path meets the performance declaration in the AISDP. If the latency exceeds the declared threshold, the test fails, preventing deployment of a version that would immediately violate a documented commitment.

Error handling must produce graceful degradation rather than silent failures. When the model receives malformed input, when a dependency is unavailable, or when the serving infrastructure is under stress, the test verifies that the system returns an appropriate error response, logs the event, and does not produce a plausible but incorrect output. Silent failures, where the system returns a default value without indicating an error, are particularly dangerous for high-risk systems because they may go undetected.

Key outputs

• Registry load tests confirming model loads via the registry client
• Output format and range validation tests
• Latency tests against declared SLA thresholds
• Graceful degradation tests for error conditions
