Overview
QA test script for validating backend configuration parsing and defaults in the Triton Inference Server.
Description
This test validates that the Triton Inference Server correctly parses backend configuration options and applies appropriate default values. It exercises various backend config settings including command-line overrides, per-backend configuration maps, and default parameter inheritance. The script generates model repositories with different backend configurations, starts the server with various config combinations, and verifies that each configuration is correctly applied by checking server behavior and log output.
Usage
Run as part of the Triton QA test suite to validate backend configuration parsing. Typically executed in CI/CD pipelines within the Triton Docker container environment.
