# 用覆寫測試相依 { #testing-dependencies-with-overrides }

## 在測試期間覆寫相依 { #overriding-dependencies-during-testing }

有些情境你可能想在測試時覆寫（override）某個相依（dependency）。

你不希望執行原本的相依（以及它可能具有的任何子相依）。

相反地，你想提供一個只在測試期間使用的不同相依（可能只在特定測試中），並回傳一個可以在原本相依值被使用之處使用的值。

### 使用情境：外部服務 { #use-cases-external-service }

例如你有一個需要呼叫的外部驗證提供者。

你傳送一個 token，它會回傳一個已驗證的使用者。

這個提供者可能按每個請求收費，而且呼叫它可能比在測試中使用固定的模擬使用者多花一些時間。

你大概只想對外部提供者測試一次，而不需要在每個測試都呼叫它。

# `Request` class

You can declare a parameter in a *path operation function* or dependency to be of type `Request` and then you can access the raw request object directly, without any validation, etc.

Read more about it in the [FastAPI docs about using Request directly](https://fastapi.tiangolo.com/advanced/using-request-directly/)

You can import it directly from `fastapi`:

```python
from fastapi import Request
```

/// tip

# Global Dependencies { #global-dependencies }

Bazı uygulama türlerinde, tüm uygulama için dependency eklemek isteyebilirsiniz.

[`dependencies`'i *path operation decorator*'larına ekleyebildiğiniz](dependencies-in-path-operation-decorators.md) gibi, `FastAPI` uygulamasına da ekleyebilirsiniz.

Bu durumda, uygulamadaki tüm *path operation*'lara uygulanırlar:

{* ../../docs_src/dependencies/tutorial012_an_py310.py hl[17] *}

plugins {
    id("gradlebuild.version-catalogs")
    id("gradlebuild.default-settings-plugins")
}

includeBuild("../build-logic-settings")

// Shared basics for all
include("basics")

// Platform: defines shared dependency versions
include("build-platform")

// Compute the identity/version we are building and related details (like current git commit)
include("module-identity")

Está diseñado para ser muy simple de usar, y para hacer que cualquier desarrollador integre otros componentes con **FastAPI** de forma muy sencilla.

## Qué es la "Inyección de Dependencias" { #what-is-dependency-injection }

**"Inyección de Dependencias"** significa, en programación, que hay una manera para que tu código (en este caso, tus *path operation functions*) declare las cosas que necesita para funcionar y utilizar: "dependencias".

* parent class
* subclass
* child class
* sibling class
* class method

* header
* headers
* authorization header
* `Authorization` header
* forwarded header

* dependency injection system
* dependency
* dependable
* dependant

* I/O bound
* CPU bound
* concurrency
* parallelism
* multiprocessing

* env var
