Overview
QA test script for validating model lifecycle management in the Triton Inference Server.
Description
This is the largest QA test script at 2245 lines, providing exhaustive validation of the model lifecycle management subsystem. It tests every aspect of model loading, unloading, versioning, and repository management including: explicit model loading and unloading via the model control API, model repository polling with configurable intervals, model version policy enforcement (latest, all, specific versions), loading models from multiple repositories, model file modification detection and automatic reload, model dependency resolution and loading order, ensemble model lifecycle coordination, configuration-only updates without model reload, graceful handling of corrupted or invalid models, concurrent load/unload operations, model availability during transitions, warmup sequence execution on load, and server behavior when the model repository is modified while requests are in flight. Each sub-test carefully verifies server state using health endpoints and inference requests.
Usage
Run as part of the Triton QA test suite to validate model lifecycle management. Typically executed in CI/CD pipelines within the Triton Docker container environment.
