### Settings and testing { #settings-and-testing }

Then it would be very easy to provide a different settings object during testing by creating a dependency override for `get_settings`:

### SIG Scalability

[SIG Scalability][] is responsible for scalability testing, measuring and
improving system performance, and answering questions related to scalability.

For the 1.8 release, SIG Scalability focused on automating large cluster
scalability testing in a continuous integration (CI) environment. The SIG
defined a concrete process for scalability testing, created

# Testing Dependencies with Overrides { #testing-dependencies-with-overrides }

## Overriding dependencies during testing { #overriding-dependencies-during-testing }

There are some scenarios where you might want to override a dependency during testing.

You don't want the original dependency to run (nor any of the sub-dependencies it might have).

- Add driver-owned fields in ResourceClaim.Status to report device status data for each allocated device. ([#128240](https://github.com/kubernetes/kubernetes/pull/128240), [@LionelJouin](https://github.com/LionelJouin)) [SIG API Machinery, Network, Node and Testing]

        * `failure-domain.beta.kubernetes.io/region`
        * `[*.]kubelet.kubernetes.io/*`
        * `[*.]node.kubernetes.io/*`
    * Setting other `kubernetes.io/`- and `k8s.io/`-prefixed labels using the `--node-labels` flag will produce a warning in v1.13, and be disallowed in v1.15. Setting labels that are not prefixed with `kubernetes.io/` or `k8s.io/` is still permitted.

  This eliminates the problem of rolling updates to a DaemonSet getting stuck around tolerations. ([#120785](https://github.com/kubernetes/kubernetes/pull/120785), [@mochizuki875](https://github.com/mochizuki875)) [SIG Apps and Testing]

# Testando { #testing }

Graças ao <a href="https://www.starlette.dev/testclient/" class="external-link" target="_blank">Starlette</a>, testar aplicações **FastAPI** é fácil e agradável.

Ele é baseado no <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, que por sua vez é projetado com base em Requests, por isso é muito familiar e intuitivo.

/// tip

如果您需要一个快速的复制粘贴示例，请不要使用此示例，而应使用下面的最后一个示例。

然后，当您创建该 `Settings` 类的实例（在此示例中是 `settings` 对象）时，Pydantic 将以不区分大小写的方式读取环境变量，因此，大写的变量 `APP_NAME` 仍将为属性 `app_name` 读取。

然后，它将转换和验证数据。因此，当您使用该 `settings` 对象时，您将获得您声明的类型的数据（例如 `items_per_user` 将为 `int` 类型）。

### 使用 `settings`

然后，您可以在应用程序中使用新的 `settings` 对象：

- Update debian-base, debian-iptables, setcap images to pick up CVE fixes
  - Debian-base to v1.9.0
  - Debian-iptables to v1.6.7
  - setcap to v2.0.4 (#106143, @cpanato) [SIG Release and Testing]

### Failing Test

- Fixes hostpath storage e2e tests within SELinux enabled env (#105786, @Elbehery) [SIG Testing]
