```

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

```

### 🔬 📁

⤴️ 👆 💪 ✔️ 📁 `test_main.py` ⏮️ 👆 💯. ⚫️ 💪 🖖 🔛 🎏 🐍 📦 (🎏 📁 ⏮️ `__init__.py` 📁):

``` hl_lines="5"
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

↩️ 👉 📁 🎏 📦, 👆 💪 ⚙️ ⚖ 🗄 🗄 🎚 `app` ⚪️➡️ `main` 🕹 (`main.py`):

```Python hl_lines="3"
{!../../../docs_src/app_testing/test_main.py!}
```

...& ✔️ 📟 💯 💖 ⏭.

## 🔬: ↔ 🖼

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

### Файл тестов

Также у Вас может быть файл `test_main.py` содержащий тесты. Можно разместить тестовый файл и файл приложения в одной директории (в директориях для Python-кода желательно размещать и файл `__init__.py`):

``` hl_lines="5"
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

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

### 测试文件

然后你会有一个包含测试的文件 `test_main.py` 。app可以像Python包那样存在（一样是目录，但有个 `__init__.py` 文件）：

``` hl_lines="5"
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

因为这文件在同一个包中，所以你可以通过相对导入从 `main` 模块（`main.py`）导入`app`对象：

```Python hl_lines="3"
{!../../../docs_src/app_testing/test_main.py!}
```

...然后测试代码和之前一样的。

## 测试：扩展示例

		switch {
		case name == "TestMain":
			if isTestFunc(n, "T") {
				t.Tests = append(t.Tests, testFunc{pkg, name, "", false})
				*doImport, *seen = true, true
				continue
			}
			err := checkTestFunc(n, "M")
			if err != nil {
				return err
			}
			if t.TestMain != nil {
				return errors.New("multiple definitions of TestMain")
			}
			t.TestMain = &testFunc{pkg, name, "", false}
