当你需要在测试中运行 `lifespan` 时，可以将 `TestClient` 与 `with` 语句一起使用：

{* ../../docs_src/app_testing/tutorial004_py310.py hl[9:15,18,27:28,30:32,41:43] *}

你可以在[官方 Starlette 文档站点的“在测试中运行 lifespan”](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)阅读更多细节。

对于已弃用的 `startup` 和 `shutdown` 事件，可以按如下方式使用 `TestClient`：

/**
 * Request body class for protected words dictionary edit operations in the admin REST API.
 * This class extends EditForm to inherit the necessary form validation and binding capabilities
 * for protected words dictionary management operations.
 */
public class EditBody extends EditForm {

    /**
     * Default constructor.
     */
    public EditBody() {
        super();

/**
 * Request body class for stemmer override dictionary edit operations in the admin REST API.
 * This class extends EditForm to inherit the necessary form validation and binding capabilities
 * for stemmer override dictionary management operations.
 */
public class EditBody extends EditForm {

    /**
     * Default constructor.
     */
    public EditBody() {
        super();

   *
   * Even if no other references to classes from the application class loader remain, the Finalizer
   * thread keeps an indirect strong reference to the queue in ReferenceMap, which keeps the
   * Finalizer running, and as a result, the application class loader can never be reclaimed.
   *
   * This means that dynamically loaded web applications and OSGi bundles can't be unloaded.
   *

    * 如果你知道 Python types，你就知道如何使用 Pydantic。
* 和你 **<abbr title="Integrated Development Environment - 集成开发环境: 类似于代码编辑器">IDE</abbr>/<dfn title="一个检查代码错误的程序">linter</dfn>/brain** 适配:
    * 因为 pydantic 数据结构仅仅是你定义的类的实例；自动补全，linting，mypy 以及你的直觉应该可以和你验证的数据一起正常工作。
* 验证**复杂结构**:
    * 使用分层的 Pydantic 模型，Python `typing` 的 `List` 和 `Dict` 等等。
    * 验证器使我们能够简单清楚地将复杂的数据模式定义、检查并记录为 JSON Schema。
    * 你可以拥有深度**嵌套的 JSON** 对象并对它们进行验证和注释。
* **可扩展**:

   * a robolectric test.
   *
   * The functionality that will fail without a valid Context is primarily Cookies and URL Domain handling, but
   * may expand in the future.

This platform is agnostic to what exactly the purpose of the work is.
It might be creating an application, setting up development environments, orchestrating deployments, running simulations, etc.

This platform does not provide special support for a particular kind of automation. This is the responsibility of other platforms.

It is made up of 3 architecture modules:
