## 分离测试

在实际应用中，你可能会把你的测试放在另一个文件里。

您的**FastAPI**应用程序也可能由一些文件/模块组成等等。

### **FastAPI** app 文件

假设你有一个像 [更大的应用](bigger-applications.md){.internal-link target=_blank} 中所描述的文件结构:

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

在 `main.py` 文件中你有一个 **FastAPI** app:


```Python

			errLineTooLong,
			nil,
			nil,
		},
		// Test - 2 - unexpected end of the reader.
		{
			bufio.NewReader(readers[1]),
			io.ErrUnexpectedEOF,
			nil,
			nil,
		},
		// Test - 3 - line too long bigger than 4k+1
		{
			bufio.NewReader(readers[2]),
			errLineTooLong,
			nil,
			nil,
		},
		// Test - 4 - parse the chunk reader properly.
		{
			bufio.NewReader(readers[3]),
			nil,
			[]byte("1000"),

```Dockerfile
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./app /app
```

### Applications plus larges

Si vous avez suivi la section sur la création d' [Applications avec plusieurs fichiers](../tutorial/bigger-applications.md){.internal-link target=_blank}, votre `Dockerfile` pourrait ressembler à ceci :

```Dockerfile
FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7

COPY ./app /app/app
```

Ela foi descontinuada do Starlette, mas se você tem código que a utilizava, você pode facilmente **migrar** para <a href="https://github.com/ciscorn/starlette-graphene3" class="external-link" target="_blank">starlette-graphene3</a>, que cobre o mesmo caso de uso e tem uma **interface quase idêntica**.

/// tip | "Dica"

func TestMaxPartID(t *testing.T) {
	sizes := []struct {
		isMax bool
		partN int
	}{
		// Test - 1 part number within max part number.
		{
			false,
			globalMaxPartID - 1,
		},
		// Test - 2 part number bigger than max part number.
		{
			true,
			globalMaxPartID + 1,
		},
	}

	for i, s := range sizes {
		isMax := isMaxPartID(s.partN)
		if isMax != s.isMax {

  public void testNewArrayListWithCapacity() {
    ArrayList<Integer> list = Lists.newArrayListWithCapacity(0);
    assertEquals(emptyList(), list);

    ArrayList<Integer> bigger = Lists.newArrayListWithCapacity(256);
    assertEquals(emptyList(), bigger);
  }

  public void testNewArrayListWithCapacity_negative() {
    assertThrows(IllegalArgumentException.class, () -> Lists.newArrayListWithCapacity(-1));
  }

  public void testNewArrayListWithCapacity() {
    ArrayList<Integer> list = Lists.newArrayListWithCapacity(0);
    assertEquals(emptyList(), list);

    ArrayList<Integer> bigger = Lists.newArrayListWithCapacity(256);
    assertEquals(emptyList(), bigger);
  }

  public void testNewArrayListWithCapacity_negative() {
    assertThrows(IllegalArgumentException.class, () -> Lists.newArrayListWithCapacity(-1));
  }
