/// info

To use `EmailStr`, first install <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and then install it, for example:

```console
$ pip install email-validator
```

or with:

```console

import static org.apache.maven.lifecycle.internal.stub.LifecycleExecutionPlanCalculatorStub.INITIALIZE;
import static org.apache.maven.lifecycle.internal.stub.LifecycleExecutionPlanCalculatorStub.INSTALL;
import static org.apache.maven.lifecycle.internal.stub.LifecycleExecutionPlanCalculatorStub.PACKAGE;
import static org.apache.maven.lifecycle.internal.stub.LifecycleExecutionPlanCalculatorStub.POST_CLEAN;

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, diese aktivieren und es dann installieren, z. B.:

```console
$ pip install python-multipart
```

## `File` und `Form` importieren { #import-file-and-form }

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[3] *}

            plugins.add(newPlugin("maven-surefire-plugin", "test"));
            plugins.add(newPlugin("maven-jar-plugin", "jar"));
            plugins.add(newPlugin("maven-install-plugin", "install"));
            plugins.add(newPlugin("maven-deploy-plugin", "deploy"));
        } else {
            plugins = Collections.emptySet();
        }

        return plugins;
    }

## 使用 `TestClient`

/// info | 信息

要使用 `TestClient`，先要安装 <a href="https://www.python-httpx.org" class="external-link" target="_blank">`httpx`</a>.

例：`pip install httpx`.

///

导入 `TestClient`.

通过传入你的**FastAPI**应用创建一个 `TestClient` 。

创建名字以 `test_` 开头的函数（这是标准的 `pytest` 约定）。

像使用 `httpx` 那样使用 `TestClient` 对象。

            <id>test</id>

            <!--  The key to this test... -->
            <inherited>false</inherited>

            <goals>
              <goal>compile</goal>
            </goals>
            <phase>install</phase>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

            ${{ matrix.java }}
            25
          distribution: 'temurin'
          cache: 'maven'
      - name: 'Install'
        shell: bash
        run: ./mvnw -B -Dorg.slf4j.simpleLogger.log.org.apache.maven.cli.transfer.Slf4jMavenTransferListener=warn -Dtoolchain.skip install -U -DskipTests=true -f $ROOT_POM
      - name: 'Test'
        shell: bash

## Abhängigkeiten installieren { #install-dependencies }

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und `jinja2` installieren:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## `Jinja2Templates` verwenden { #using-jinja2templates }

        <test>org.apache.maven.plugins:maven-surefire-plugin:test</test>
        <package>org.apache.maven.plugins:maven-jar-plugin:jar</package>
        <install>org.apache.maven.plugins:maven-install-plugin:install</install>
        <deploy>org.apache.maven.plugins:maven-deploy-plugin:deploy</deploy>
      </phases>
    </lifecycle>
  </lifecycles>
</configuration>

## Установка зависимостей { #install-dependencies }

Убедитесь, что вы создали [виртуальное окружение](../virtual-environments.md){.internal-link target=_blank}, активировали его и установили `jinja2`:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## Использование `Jinja2Templates` { #using-jinja2templates }
