環境変数は、アプリケーションの**設定**の扱い、Pythonの**インストール**の一部などで役立ちます。

## 環境変数の作成と使用 { #create-and-use-env-vars }

環境変数は、Pythonを必要とせず、**シェル（ターミナル）**で**作成**して使用できます。

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// 環境変数 MY_NAME を作成する例
$ export MY_NAME="Wade Wilson"

// その後、他のプログラムで利用できます。例えば
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

#### 4. Run Integration Tests

    $ mvn test -P integrationTests -Dtest.fess.url="http://localhost:8080" -Dtest.search_engine.url="http://localhost:9201"

To run a single test case:

    $ mvn test -P integrationTests -Dtest.fess.url="http://localhost:8080" -Dtest.search_engine.url="http://localhost:9201" -Dtest=SearchApiTests

 * <p>Occasionally, an API will return a plain {@code Future} and it will be impossible to change
