For a simple example, let's consider a file structure similar to the one described in [Bigger Applications](../tutorial/bigger-applications.md) and [Testing](../tutorial/testing.md):

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

The file `main.py` would have:

{* ../../docs_src/async_tests/app_a_py310/main.py *}

        assertEquals("/share/file.txt", context.get("path"));
        assertEquals("testuser", context.get("user"));
    }

Et votre application **FastAPI** pourrait aussi être composée de plusieurs fichiers/modules, etc.

### Fichier d’application **FastAPI** { #fastapi-app-file }

Supposons que vous ayez une structure de fichiers comme décrit dans [Applications plus grandes](bigger-applications.md) :

```
.
├── app
│   ├── __init__.py
│   └── main.py
```

PROC_NAME=org.codelibs.fess.FessBoot
FESS_USER="${packaging.fess.user}"
FESS_GROUP="${packaging.fess.group}"
FESS_HOME="${packaging.fess.home.dir}"
PID_DIR="${packaging.fess.pid.dir}"

# Source the default env file
FESS_ENV_FILE="${packaging.env.file}"
if [ -f "$FESS_ENV_FILE" ]; then
    . "$FESS_ENV_FILE"
fi

exec="$FESS_HOME/bin/fess"
prog="fess"
pidfile="$PID_DIR/${prog}.pid"

export FESS_TEMP_PATH
export FESS_LOG_PATH
