Overview

QA test script for validating response caching functionality in the Triton Inference Server.

Description

This test validates the Triton Inference Server's response cache, which stores inference results to avoid redundant computation for repeated requests. It verifies that cache hits return correct results matching the original inference output, that cache misses are properly computed and stored, and that the cache respects configured size limits and eviction policies. The test also checks that cache behavior is correct across different model types and that cache metrics are accurately reported.

Usage

Run as part of the Triton QA test suite. Requires a GPU-enabled Docker environment with pre-generated test models.
