```python
from main import app
```

Якщо ваш код має таку структуру:

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

Тоді ви встановили б `entrypoint` як:

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

що еквівалентно:

```python
from backend.main import app
```

```

/// note

The command `uvicorn main:app` refers to:

* `main`: the file `main.py` (the Python "module").
* `app`: the object created inside of `main.py` with the line `app = FastAPI()`.

It is equivalent to:

```Python
from main import app
```

///

        }).when(mockDcerpcHandle).sendrecv(any(MsrpcSamrCloseHandle.class));

        // First close call
        aliasHandle.close();

        // Act: Call close again
        aliasHandle.close();

        // Assert: Verify sendrecv for MsrpcSamrCloseHandle was called only once
        verify(mockDcerpcHandle, times(1)).sendrecv(any(MsrpcSamrCloseHandle.class));
    }
