# MNNCLI Test Script
# This script tests various functionalities of mnncli
#
# Test matrix (high-level):
# - Basic commands: help, version, list
# - Search across providers: huggingface, modelscope, modelers (keyword: SmolVLM2)
# - Isolated cache: set cache_dir to ~/.cache/mnnclitest/mnnmodels, restore after tests
# - Pre/post list assertions around real downloads
# - Real downloads with timeout + retry for SmolVLM2-256M-Video-Instruct-MNN
#   * HuggingFace: taobao-mnn/SmolVLM2-256M-Video-Instruct-MNN
#   * ModelScope:  MNN/SmolVLM2-256M-Video-Instruct-MNN
#   * Modelers:    MNN/SmolVLM2-256M-Video-Instruct-MNN
# - Idempotency: second download should succeed quickly/no-op
# - Cleanup: restore original cache_dir & provider, remove test cache directory
#
# Notes:
# - MNNCLI expects a directory containing config.json, not the .mnn file directly.
#   You can either:
#   1) Pass the directory path: mnncli run <model_directory>
#   2) Use the -c flag: mnncli run -c <path/to/config.json>
