Server tests

Python based server tests scenario using BDD and behave:

• issues.feature Pending issues scenario
• parallel.feature Scenario involving multi slots and concurrent requests
• security.feature Security, CORS and API Key
• server.feature Server base scenario: completion, embedding, tokenization, etc...

Tests target GitHub workflows job runners with 4 vCPU.

Requests are using aiohttp, asyncio based http client.

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

cd ../../..
mkdir build
cd build
cmake -DLLAMA_CURL=ON ../
cmake --build . --target 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/server
DEBUG	"ON" to enable steps and server verbose mode --verbose
SERVER_LOG_FORMAT_JSON	if set switch server logs to json format
N_GPU_LAYERS	number of model layers to offload to VRAM -ngl --n-gpu-layers

Run @bug, @wip or @wrong_usage annotated scenario

Feature or Scenario must be annotated with @llama.cpp to be included in the default scope.

• @bug annotation aims to link a scenario with a GitHub issue.
• @wrong_usage are meant to show user issue that are actually an expected behavior
• @wip to focus on a scenario working in progress
• @slow heavy test, disabled by default

To run a scenario annotated with @bug, start:

DEBUG=ON ./tests.sh --no-skipped --tags bug --stop

After changing logic in steps.py, ensure that @bug and @wrong_usage scenario are updated.

./tests.sh --no-skipped --tags bug,wrong_usage || echo "should failed but compile"
