+# Server tests
+
+Python based server tests scenario using [BDD](https://en.wikipedia.org/wiki/Behavior-driven_development) and [behave](https://behave.readthedocs.io/en/latest/):
+ * [issues.feature](./features/issues.feature) Pending issues scenario
+ * [parallel.feature](./features/parallel.feature) Scenario involving multi slots and concurrent requests
+ * [security.feature](./features/security.feature) Security, CORS and API Key
+ * [server.feature](./features/server.feature) Server base scenario: completion, embedding, tokenization, etc...
+
+Tests target GitHub workflows job runners with 4 vCPU.
+
+Requests are using [aiohttp](https://docs.aiohttp.org/en/stable/client_reference.html), [asyncio](https://docs.python.org/fr/3/library/asyncio.html) 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
+```shell
+cd ../../..
+mkdir build
+cd build
+cmake ../
+cmake --build . --target server
+```
+2. download required models:
+ 1. `../../../scripts/hf.sh --repo ggml-org/models --file tinyllamas/stories260K.gguf`
+3. Start the test: `./tests.sh`
+
+It's possible to override some scenario steps values with environment variables:
+ - `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`
+
+### 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
+
+To run a scenario annotated with `@bug`, start:
+`DEBUG=ON ./tests.sh --no-skipped --tags bug`
+
+After changing logic in `steps.py`, ensure that `@bug` and `@wrong_usage` scenario are updated.
