# 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...
Python based server tests scenario using [pytest](https://docs.pytest.org/en/stable/).
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`.
@ -39,26 +29,19 @@ 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/llama-server` |
| `DEBUG` | "ON" to enable steps and server verbose mode `--verbose` |
| `DEBUG` | to enable steps and server verbose mode `--verbose` |
| `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:
To run slow tests:
```shell
DEBUG=ON ./tests.sh --no-skipped --tags bug --stop
SLOW_TESTS=1 ./tests.sh
```
After changing logic in `steps.py`, ensure that `@bug` and `@wrong_usage` scenario are updated.
To run with stdout/stderr display in real time (verbose output, but useful for debugging):
```shell
./tests.sh --no-skipped --tags bug,wrong_usage || echo "should failed but compile"
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)
