### Đã được kiểm thử

* 100% <abbr title=" Lượng code đã được kiểm thử tự động">test coverage</abbr>.
* 100% <abbr title="Python type annotations, với điều này trình soạn thảo của bạn và các công cụ bên ngoài có thể hỗ trợ bạn tốt hơn">type annotated</abbr> code base.

* **不依赖**数据库，前端等。 但是和它们集成很简单。

### 无限制"插件"

或者说，导入并使用你需要的代码，而不需要它们。

任何集成都被设计得被易于使用（用依赖关系），你可以用和*路径操作*相同的结构和语法，在两行代码中为你的应用创建一个“插件”。

### 测试

* 100% <abbr title="自动测试的代码量">测试覆盖</abbr>。
* 代码库100% <abbr title="Python类型注解，有了这个你的编辑器和外部工具可以给你更好的支持">类型注释</abbr>。
* 用于生产应用。
