Python based server tests scenario using [pytest](https://docs.pytest.org/en/stable/).
Tests target GitHub workflows job runners with 4 vCPU.
Note: If the host architecture inference speed is faster than GitHub runners one, parallel scenario may randomly fail.
To mitigate it, you can increase values in `n_predict`, `kv_size`.
### Install dependencies
`pip install -r requirements.txt`
### Run tests
1. Build the server
```shell
cd ../../..
cmake -B build
cmake --build build --target llama-server
```
2. Start the test: `./tests.sh`
It's possible to override some scenario steps values with environment variables:
| variable | description |
|--------------------------|------------------------------------------------------------------------------------------------|
| `PORT` | `context.server_port` to set the listening port of the server during scenario, default: `8080` |
| `LLAMA_SERVER_BIN_PATH` | to change the server binary path, default: `../../../build/bin/llama-server` |
| `DEBUG` | to enable steps and server verbose mode `--verbose` |
| `N_GPU_LAYERS` | number of model layers to offload to VRAM `-ngl --n-gpu-layers` |
| `LLAMA_CACHE` | by default server tests re-download models to the `tmp` subfolder. Set this to your cache (e.g. `$HOME/Library/Caches/llama.cpp` on Mac or `$HOME/.cache/llama.cpp` on Unix) to avoid this |
To run slow tests (will download many models, make sure to set `LLAMA_CACHE` if needed):
```shell
SLOW_TESTS=1 ./tests.sh
```
To run with stdout/stderr display in real time (verbose output, but useful for debugging):
```shell
DEBUG=1 ./tests.sh -s -v -x
```
To run all the tests in a file:
```shell
./tests.sh unit/test_chat_completion.py -v -x
```
To run a single test:
```shell
./tests.sh unit/test_chat_completion.py::test_invalid_chat_completion_req
```
Hint: You can compile and run test in single command, useful for local developement:
```shell
cmake --build build -j --target llama-server && ./tools/server/tests/tests.sh
```
To see all available arguments, please refer to [pytest documentation](https://docs.pytest.org/en/stable/how-to/usage.html)
