refactor(test): introduce --stack-config and simplify options (#1404)

Browse source 
You now run the integration tests with these options:

```bash
Custom options:
  --stack-config=STACK_CONFIG
                        a 'pointer' to the stack. this can be either be:
                        (a) a template name like `fireworks`, or
                        (b) a path to a run.yaml file, or
                        (c) an adhoc config spec, e.g.
                        `inference=fireworks,safety=llama-guard,agents=meta-
                        reference`
  --env=ENV             Set environment variables, e.g. --env KEY=value
  --text-model=TEXT_MODEL
                        comma-separated list of text models. Fixture name:
                        text_model_id
  --vision-model=VISION_MODEL
                        comma-separated list of vision models. Fixture name:
                        vision_model_id
  --embedding-model=EMBEDDING_MODEL
                        comma-separated list of embedding models. Fixture name:
                        embedding_model_id
  --safety-shield=SAFETY_SHIELD
                        comma-separated list of safety shields. Fixture name:
                        shield_id
  --judge-model=JUDGE_MODEL
                        comma-separated list of judge models. Fixture name:
                        judge_model_id
  --embedding-dimension=EMBEDDING_DIMENSION
                        Output dimensionality of the embedding model to use for
                        testing. Default: 384
  --record-responses    Record new API responses instead of using cached ones.
  --report=REPORT       Path where the test report should be written, e.g.
                        --report=/path/to/report.md

```

Importantly, if you don't specify any of the models (text-model,
vision-model, etc.) the relevant tests will get **skipped!**

This will make running tests somewhat more annoying since all options
will need to be specified. We will make this easier by adding some easy
wrapper yaml configs.

## Test Plan

Example:

```bash
ashwin@ashwin-mbp ~/local/llama-stack/tests/integration (unify_tests) $ 
LLAMA_STACK_CONFIG=fireworks pytest -s -v inference/test_text_inference.py \
   --text-model meta-llama/Llama-3.2-3B-Instruct 
```

# Testing Llama Stack Providers
The Llama Stack is designed as a collection of Lego blocks -- various APIs -- which are composable and can be used to quickly and reliably build an app. We need a testing setup which is relatively flexible to enable easy combinations of these providers.
We use `pytest` and all of its dynamism to enable the features needed. Specifically:
- We use `pytest_addoption` to add CLI options allowing you to override providers, models, etc.
- We use `pytest_generate_tests` to dynamically parametrize our tests. This allows us to support a default set of (providers, models, etc.) combinations but retain the flexibility to override them via the CLI if needed.
- We use `pytest_configure` to make sure we dynamically add appropriate marks based on the fixtures we make.
- We use `pytest_collection_modifyitems` to filter tests based on the test config (if specified).
## Pre-requisites
Your development environment should have been configured as per the instructions in the
[CONTRIBUTING.md](../../../CONTRIBUTING.md) file. In particular, make sure to install the test extra
dependencies. Below is the full configuration:
```bash
cd llama-stack
uv sync --extra dev --extra test
uv pip install -e .
source .venv/bin/activate
```
## Common options
All tests support a `--providers` option which can be a string of the form `api1=provider_fixture1,api2=provider_fixture2`. So, when testing safety (which need inference and safety APIs) you can use `--providers inference=together,safety=meta_reference` to use these fixtures in concert.
Depending on the API, there are custom options enabled. For example, `inference` tests allow for an `--inference-model` override, etc.
By default, we disable warnings and enable short tracebacks. You can override them using pytest's flags as appropriate.
Some providers need special API keys or other configuration options to work. You can check out the individual fixtures (located in `tests/<api>/fixtures.py`) for what these keys are. These can be specified using the `--env` CLI option. You can also have it be present in the environment (exporting in your shell) or put it in the `.env` file in the directory from which you run the test. For example, to use the Together fixture you can use `--env TOGETHER_API_KEY=<...>`
## Inference
We have the following orthogonal parametrizations (pytest "marks") for inference tests:
- providers: (meta_reference, together, fireworks, ollama)
- models: (llama_8b, llama_3b)
If you want to run a test with the llama_8b model with fireworks, you can use:
```bash
pytest -s -v llama_stack/providers/tests/inference/test_text_inference.py \
-m "fireworks and llama_8b" \
--env FIREWORKS_API_KEY=<...>
```
You can make it more complex to run both llama_8b and llama_3b on Fireworks, but only llama_3b with Ollama:
```bash
pytest -s -v llama_stack/providers/tests/inference/test_text_inference.py \
-m "fireworks or (ollama and llama_3b)" \
--env FIREWORKS_API_KEY=<...>
```
Finally, you can override the model completely by doing:
```bash
pytest -s -v llama_stack/providers/tests/inference/test_text_inference.py \
-m fireworks \
--inference-model "meta-llama/Llama3.1-70B-Instruct" \
--env FIREWORKS_API_KEY=<...>
```
> [!TIP]
> If you’re using `uv`, you can isolate test executions by prefixing all commands with `uv run pytest...`.
## Agents
The Agents API composes three other APIs underneath:
- Inference
- Safety
- Memory
Given that each of these has several fixtures each, the set of combinations is large. We provide a default set of combinations (see `tests/agents/conftest.py`) with easy to use "marks":
- `meta_reference` -- uses all the `meta_reference` fixtures for the dependent APIs
- `together` -- uses Together for inference, and `meta_reference` for the rest
- `ollama` -- uses Ollama for inference, and `meta_reference` for the rest
An example test with Together:
```bash
pytest -s -m together llama_stack/providers/tests/agents/test_agents.py \
--env TOGETHER_API_KEY=<...>
```
If you want to override the inference model or safety model used, you can use the `--inference-model` or `--safety-shield` CLI options as appropriate.
If you wanted to test a remotely hosted stack, you can use `-m remote` as follows:
```bash
pytest -s -m remote llama_stack/providers/tests/agents/test_agents.py \
--env REMOTE_STACK_URL=<...>
```
## Test Config
If you want to run a test suite with a custom set of tests and parametrizations, you can define a YAML test config under llama_stack/providers/tests/ folder and pass the filename through `--config` option as follows:
```
pytest llama_stack/providers/tests/ --config=ci_test_config.yaml
```
### Test config format
Currently, we support test config on inference, agents and memory api tests.
Example format of test config can be found in ci_test_config.yaml.
## Test Data
We encourage providers to use our test data for internal development testing, so to make it easier and consistent with the tests we provide. Each test case may define its own data format, and please refer to our test source code to get details on how these fields are used in the test.

# Llama Stack Integration Tests # Llama Stack Integration Tests
You can run llama stack integration tests on either a Llama Stack Library or a Llama Stack endpoint.
To test on a Llama Stack library with certain configuration, run We use `pytest` for parameterizing and running tests. You can see all options with:
```bash ```bash
LLAMA_STACK_CONFIG=./llama_stack/templates/cerebras/run.yaml pytest -s -v tests/api/inference/ cd tests/integration
```
or just the template name # this will show a long list of options, look for "Custom options:"
```bash pytest --help
LLAMA_STACK_CONFIG=together pytest -s -v tests/api/inference/
``` ```
To test on a Llama Stack endpoint, run Here are the most important options:
- `--stack-config`: specify the stack config to use. You have three ways to point to a stack:
- a URL which points to a Llama Stack distribution server
- a template (e.g., `fireworks`, `together`) or a path to a run.yaml file
- a comma-separated list of api=provider pairs, e.g. `inference=fireworks,safety=llama-guard,agents=meta-reference`. This is most useful for testing a single API surface.
- `--env`: set environment variables, e.g. --env KEY=value. this is a utility option to set environment variables required by various providers.
Model parameters can be influenced by the following options:
- `--text-model`: comma-separated list of text models.
- `--vision-model`: comma-separated list of vision models.
- `--embedding-model`: comma-separated list of embedding models.
- `--safety-shield`: comma-separated list of safety shields.
- `--judge-model`: comma-separated list of judge models.
- `--embedding-dimension`: output dimensionality of the embedding model to use for testing. Default: 384
Each of these are comma-separated lists and can be used to generate multiple parameter combinations.
Experimental, under development, options:
- `--record-responses`: record new API responses instead of using cached ones
- `--report`: path where the test report should be written, e.g. --report=/path/to/report.md
## Examples
Run all text inference tests with the `together` distribution:
```bash ```bash
LLAMA_STACK_BASE_URL=http://localhost:8089 pytest -s -v tests/api/inference pytest -s -v tests/api/inference/test_text_inference.py \
--stack-config=together \
--text-model=meta-llama/Llama-3.1-8B-Instruct
``` ```
## Report Generation Run all text inference tests with the `together` distribution and `meta-llama/Llama-3.1-8B-Instruct`:
To generate a report, run with `--report` option
```bash ```bash
LLAMA_STACK_CONFIG=together pytest -s -v report.md tests/api/ --report pytest -s -v tests/api/inference/test_text_inference.py \
--stack-config=together \
--text-model=meta-llama/Llama-3.1-8B-Instruct
``` ```
## Common options Running all inference tests for a number of models:
Depending on the API, there are custom options enabled
- For tests in `inference/` and `agents/, we support `--inference-model` (to be used in text inference tests) and `--vision-inference-model` (only used in image inference tests) overrides ```bash
- For tests in `vector_io/`, we support `--embedding-model` override TEXT_MODELS=meta-llama/Llama-3.1-8B-Instruct,meta-llama/Llama-3.1-70B-Instruct
- For tests in `safety/`, we support `--safety-shield` override VISION_MODELS=meta-llama/Llama-3.2-11B-Vision-Instruct
- The param can be `--report` or `--report <path>` EMBEDDING_MODELS=all-MiniLM-L6-v2
If path is not provided, we do a best effort to infer based on the config / template name. For url endpoints, path is required. TOGETHER_API_KEY=...
pytest -s -v tests/api/inference/ \
--stack-config=together \
--text-model=$TEXT_MODELS \
--vision-model=$VISION_MODELS \
--embedding-model=$EMBEDDING_MODELS
```
Same thing but instead of using the distribution, use an adhoc stack with just one provider (`fireworks` for inference):
```bash
FIREWORKS_API_KEY=...
pytest -s -v tests/api/inference/ \
--stack-config=inference=fireworks \
--text-model=$TEXT_MODELS \
--vision-model=$VISION_MODELS \
--embedding-model=$EMBEDDING_MODELS
```
Running Vector IO tests for a number of embedding models:
```bash
EMBEDDING_MODELS=all-MiniLM-L6-v2
pytest -s -v tests/api/vector_io/ \
--stack-config=inference=sentence-transformers,vector_io=sqlite-vec \
--embedding-model=$EMBEDDING_MODELS
```
