  Alice opened the door and found that it led into a small
passage, not much larger than a rat-hole:  she knelt down and
looked along the passage into the loveliest garden you ever saw.
How she longed to get out of that dark hall, and wander about
among those beds of bright flowers and those cool fountains, but

## 예시 { #example }

간단한 예시로, [더 큰 애플리케이션](../tutorial/bigger-applications.md)과 [테스트](../tutorial/testing.md)에서 설명한 것과 비슷한 파일 구조를 살펴보겠습니다:

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

`main.py` 파일은 다음과 같습니다:

    @ValueSource(ints = { 1, 10, 100, 500, 1024 })
    void testReadDataWireFormatWithVariousSizes(int dataSize) throws SMBProtocolDecodingException {
        if (dataSize > outputBuffer.length) {
            return; // Skip sizes larger than buffer
        }

        byte[] sourceData = new byte[dataSize];
        for (int i = 0; i < dataSize; i++) {
            sourceData[i] = (byte) (i % 256);
        }

### Archivo de aplicación **FastAPI** { #fastapi-app-file }

Digamos que tienes una estructura de archivos como se describe en [Aplicaciones Más Grandes](bigger-applications.md):

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

En el archivo `main.py` tienes tu aplicación de **FastAPI**:


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

### Файл приложения **FastAPI** { #fastapi-app-file }

Допустим, структура файлов Вашего приложения похожа на ту, что описана на странице [Более крупные приложения](bigger-applications.md):

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

В файле `main.py` находится Ваше приложение **FastAPI**:


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

var errSignatureMismatch = errors.New("Signature does not match")

// When upload object size is greater than 5G in a single PUT/POST operation.
var errDataTooLarge = errors.New("Object size larger than allowed limit")

// When upload object size is less than what was expected.
var errDataTooSmall = errors.New("Object size smaller than expected")

// errServerNotInitialized - server not initialized.
