```

In the file `main.py` you have your **FastAPI** app:


```Python
{!../../../docs_src/app_testing/main.py!}
```

### Testing file

Then you could have a file `test_main.py` with your tests. It could live on the same Python package (the same directory with a `__init__.py` file):

``` hl_lines="5"
.
├── app

import java.util.concurrent.atomic.AtomicBoolean;

import org.codelibs.fess.helper.SystemHelper;
import org.codelibs.fess.mylasta.direction.FessConfig;
import org.codelibs.fess.unit.UnitFessTestCase;
import org.codelibs.fess.util.ComponentUtil;

public class LdapManagerTest extends UnitFessTestCase {

    @Override
    public void setUp() throws Exception {
        super.setUp();
        ComponentUtil.register(new SystemHelper(), "systemHelper");

    protected volatile List<PathMapping> cachedPathMappingList = null;

    @PostConstruct
    public void init() {
        if (logger.isDebugEnabled()) {
            logger.debug("Initialize {}", this.getClass().getSimpleName());
        }
        load();
    }

    @Override
    public int load() {
        final List<String> ptList = getProcessTypeList();

        try {

│   └── main.py
```

In der Datei `main.py` haben Sie Ihre **FastAPI**-Anwendung:


```Python
{!../../../docs_src/app_testing/main.py!}
```

### Testdatei

Dann könnten Sie eine Datei `test_main.py` mit Ihren Tests haben. Sie könnte sich im selben Python-Package befinden (dasselbe Verzeichnis mit einer `__init__.py`-Datei):

``` hl_lines="5"
.

    query_scheme = APIKeyQuery(name="api_key")


    @app.get("/items/")
    async def read_items(api_key: str = Depends(query_scheme)):

    """

        self,
        *,
        name: Annotated[
            str,
            Doc("Query parameter name."),
        ],
        scheme_name: Annotated[

			case subCh <- entry:
			case <-doneCh:
				return nil
			}
		}
	}
	return sys.pubsub.Subscribe(madmin.LogMaskAll, subCh, doneCh, filter)
}

// Init if HTTPConsoleLoggerSys is valid, always returns nil right now
func (sys *HTTPConsoleLoggerSys) Init(_ context.Context) error {
	return nil

// Endpoint - dummy function for interface compatibility
func (sys *HTTPConsoleLoggerSys) Endpoint() string {

public class TermQueryCommandTest extends UnitFessTestCase {
    private static final Logger logger = LogManager.getLogger(TermQueryCommandTest.class);

    private TermQueryCommand queryCommand;

    @Override
    public void setUp() throws Exception {
        super.setUp();

        QueryFieldConfig queryFieldConfig = new QueryFieldConfig();
        queryFieldConfig.init();

## Die Instanz parametrisieren

Und jetzt können wir `__init__` verwenden, um die Parameter der Instanz zu deklarieren, die wir zum `Parametrisieren` der Abhängigkeit verwenden können:

=== "Python 3.9+"

    ```Python hl_lines="9"

		fi
	fi
}

function check_online() {
	if ! grep -q 'Status:' ${WORK_DIR}/dist-minio-*.log; then
		echo "1"
	fi
}

function purge() {
	rm -rf "$1"
}

function __init__() {
	echo "Initializing environment"
	mkdir -p "$WORK_DIR"
	mkdir -p "$MINIO_CONFIG_DIR"

	## version is purposefully set to '3' for minio to migrate configuration file
