Significantly simpler and malleable test setup (#360)
* Significantly simpler and malleable test setup * convert memory tests * refactor fixtures and add support for composable fixtures * Fix memory to use the newer fixture organization * Get agents tests working * Safety tests work * yet another refactor to make this more general now it accepts --inference-model, --safety-model options also * get multiple providers working for meta-reference (for inference + safety) * Add README.md --------- Co-authored-by: Ashwin Bharambe <ashwin@meta.com>

# How to run this test:
|
||||
#
|
||||
# 1. Ensure you have a conda environment with the right dependencies installed.
|
||||
# This includes `pytest` and `pytest-asyncio`.
|
||||
#
|
||||
# 2. Copy and modify the provider_config_example.yaml depending on the provider you are testing.
|
||||
#
|
||||
# 3. Run:
|
||||
#
|
||||
# ```bash
|
||||
# PROVIDER_ID=<your_provider> \
|
||||
# MODEL_ID=<your_model> \
|
||||
# PROVIDER_CONFIG=provider_config.yaml \
|
||||
# pytest -s llama_stack/providers/tests/agents/test_agents.py \
|
||||
# --tb=short --disable-warnings
|
||||
# ```
