# 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 ``` Hint: You can compile and run test in single command, useful for local developement: ```shell cmake --build build -j --target llama-server && ./examples/server/tests/tests.sh ``` To see all available arguments, please refer to [pytest documentation](https://docs.pytest.org/en/stable/how-to/usage.html)
