| # Server tests | |
| 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 -DLLAMA_CURL=ON | |
| 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` | | |
| To run slow tests: | |
| ```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 see all available arguments, please refer to [pytest documentation](https://docs.pytest.org/en/stable/how-to/usage.html) | |
