Test関連の変更点

Spring Framework 5.0では、テスト機能に対して以下のような変更が行われています。

項番	変更内容
1	Spring TestContext Framework(TCF)をJUnit 5 Jupiter上で利用できるようになります。 [詳細へ] Note: SpringExtensionクラス、@SpringJUnitConfigアノテーション、@SpringJUnitWebConfigアノテーション、@EnabledIfアノテーション、@DisabledIfアノテーションが追加されます。
2	Spring TestContext Frameworkを使用したテストを平行実行できるようになります。 [詳細へ]
3	TestExecutionListenerインタフェースに、テストの実行直前と実行直後に呼び出されるコールバックメソッド(beforeTestExecutionとafterTestExecution)が追加されます。 [詳細へ]
4	MockHttpServletRequestにリクエストBODYにアクセスするためのメソッド(getContentAsByteArrayとgetContentAsString)が追加されます。 [詳細へ]
5	MockMvc使用時のテスト結果をコンソールまたはログに出力する際(MockMvcResultHandlersのprintまたはlogメソッドを使用する際)に、リクエストBODYも出力されるようになります。 [詳細へ]
6	MockMvc使用時の「リダイレクト先URL」と「フォワード先URL」を検証する際に、期待値にURIテンプレートを指定できるようになります。 [詳細へ]
7	XMLの検証をサポートするライブラリであるXMLUnitのサポートバージョンが2.3になります。 [詳細へ]

JUnit 5がサポートされる

[SPR-13575] : Spring Framework 5.0におけるテスト関連の変更点の目玉は、なんといってもJUnit 5 Jupiter上でSpring TestContext Framework(TCF)が利用できるように対応されることでしょう。具体的には・・・

クラス(アノテーション)	説明
SpringExtension	Junit 5が提供している「拡張ポイント(Extension)」を利用して、Junit 5上でSpring TestContext Frameworkを使えるようにしているクラスです。 JUnit 4上ではSpringRunner、SpringClassRuleやSpringMethodRuleが同じ役割を担っています。
@SpringJUnitConfig	Junit 5上でSpring TestContext Frameworkを利用することを示すための合成アノテーション(@ExtendWith(SpringExtension.class) + @ContextConfiguration)です。
@SpringJUnitWebConfig	Junit 5上でWEB環境向けのSpring TestContext Frameworkを利用することを示すための合成アノテーション(@ExtendWith(SpringExtension.class) + @ContextConfiguration + @WebAppConfiguration)です。
@EnabledIf	指定した条件を充す（SpELで指定したExpressionの結果がtrueになる）場合にテストを実行することを示すアノテーションです。
@DisabledIf	指定した条件を充す（SpELで指定したExpressionの結果がtrueになる）場合にテストをスキップすることを示すアノテーションです。

が追加されます。
なお、TCF自体の機能はJUnit 4上でもJUnit 5上でも同じなので、TCFの機能に対する説明は本エントリーでは割愛します。あくまで、TCFを使えるようにするための方法などが変わるだけです。

Junit 5でテストを動かしてみよう

本エントリーではJunit 5の説明は基本的には行いませんが、Junit 5上でテストするための環境は必要です。ということで・・・とりあえずJunit 5を使うMavenプロジェクトを作成して簡単なテストを実行してみます。

まず、任意のディレクトリ(例： /usr/local/apps/spring5-test-demo)を作成し、そのディレクトリ内のディレクトリ構成を以下のようにします。

$ mkdir -p /usr/local/apps/spring5-test-demo
$ cd /usr/local/apps/spring5-test-demo
...
$ tree
.
└── src
    ├── main
    │   ├── java
    │   └── resources
    └── test
        ├── java
        └── resources

つぎに、pom.xmlを作成します。

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </dependency>
  </dependencies>

  <build>
    <plugins>
      <plugin>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.19.1</version> <!-- 執筆時点の最新は2.20でしたが、テスト失敗時にOutOfMemoryErrorがでるためバージョンを下げています・・・ -->
        <dependencies>
          <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-surefire-provider</artifactId>
            <version>${junit-platform.version}</version>
          </dependency>
          <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>${junit-jupiter.version}</version>
          </dependency>
        </dependencies>
      </plugin>
    </plugins>
  </build>

</project>

Note:
maven-surefire-plugin 2.20 + JUnit 5でOutOfMemoryErrorがでる件は、次のマイルストーンリリース(5.0.0.M5)で解消される予定です。

最後にテストクラスを作成します。

package com.example.spring5testdemo;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

class SimpleJunit5Test {

    @Test
    void simpleTest() {
        Assertions.assertEquals("test", "test");
    }

}

このプロジェクトをJunit 5をサポートしているIDEにインポートし、IDEの機能を使ってJunit 5上でテストを実行することもできますが、ここではMavenプラグイン(maven-surefire-plugin)を使用してテストを実行してみます。

SpringExtensionを試す

JUnit 5上でSpring TestContext Frameworkを利用する場合は、SpringExtensionの指定が必要になりますが、まずSpring Testを使えるようにするために、pom.xmlを以下のように修正する必要があります。

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

Note:

ログ出力ライブラリを追加しないとmaven-surefire-pluginを使ってテストを実行する際にエラーになってしまいます。なぜエラーになるのか？なぜライブラリ追加するとエラーが出ないのかわからいので・・・とりあえずSpringのJIRA(SPR-15572)をあげておきました。ちなみにIntelliJの機能でテストを実行する際はエラーになりませんでした。（Eclipse/STSでは試してません）

ライブラリの追加が終わったら、実際にテストクラスを作成してみましょう。

package com.example.spring5testdemo;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.junit.jupiter.SpringExtension;

@ExtendWith(SpringExtension.class) // ★★★ SpringExtensionを指定
class SpringTcfOnJunit5Test {

    @Autowired private ApplicationContext applicationContext;

    @Test
    void defaultContextTest() {
        Assertions.assertEquals(1, applicationContext.getBeansOfType(MessageSource.class).size());
    }

    // 何かしらBean定義ファイル(XML or JavaConfig)が必要なので、ここではstaticインナークラスとしてJavaConfigクラスを作っておく
    // staticインナークラスとしてJavaConfigクラスを作っておくとTCFが自動検出してくれる
    @Configuration 
    static class LocalTestContext {}

}

テストを実行すると・・・以下のようなログが出力され、Spring TCFがApplicationContext(DIコンテナ)を生成していることがわかります。

$ mvn test

Note:

JUnit 5上でMockMvcを使用する場合は、実行結果を検証するコンポーネントがHamcrestのMatcherの仕組みを利用しているため、hamcrest-coreを依存ライブラリに追加してください。

  <artifactId>hamcrest-core</artifactId>

  <scope>test</scope>
</dependency>

@SpringJUnitConfigを試す

@SpringJUnitConfigは、Junit 5上でSpring TestContext Frameworkを利用することを示すための合成アノテーション(@ExtendWith(SpringExtension.class) + @ContextConfiguration)で、必要に応じて@ContextConfigurationが提供している属性を指定することができます。

package com.example.spring5testdemo;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.junit.jupiter.SpringJUnitConfig;

@SpringJUnitConfig // ★★★ @ExtendWith(SpringExtension.class)の代わりに指定
class SpringJUnitConfigOnJunit5Test {

    @Autowired private ApplicationContext applicationContext;

    @Test
    void defaultContextTest() {
        Assertions.assertEquals(1, applicationContext.getBeansOfType(MessageSource.class).size());
    }

    @Configuration
    static class LocalTestContext {}

}

デフォルトの動作を変更したい場合は・・・

テスト向けに用意されたJavaConfigクラスを使う場合

@SpringJUnitConfig(GlobalTestContext.class)
class SpringJUnitConfigOnJunit5Test {
    // ...
}

といった感じで、@SpringJUnitConfigの属性を使うことができます。

@SpringJUnitWebConfigを試す

@SpringJUnitWebConfigは、@SpringJUnitConfigのWEB版で、@SpringJUnitConfigとの違いは@WebAppConfigurationが付与されている/いないの違いだけです。

実際に@SpringJUnitWebConfigを試すには、いくつか依存ライブラリを追加する必要があります。具体的には・・・・

• spring-web
• Servlet API 3.1+

です。このあたりはテスト対象のアプリケーションを作る or 動かす時に必要になるので普段はあまり気にしなくてもよい部分だとは思います。

pom.xml

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-web</artifactId>
</dependency>
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.1.0</version>
  <scope>provided</scope>
</dependency>

ライブラリを追加したら、@SpringJUnitWebConfigを付与したテストケースクラスを作ります。

package com.example.spring5testdemo;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Configuration;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpSession;
import org.springframework.mock.web.MockServletContext;
import org.springframework.test.context.junit.jupiter.web.SpringJUnitWebConfig;
import org.springframework.web.context.support.GenericWebApplicationContext;

@SpringJUnitWebConfig // ★★★ @ExtendWith(SpringExtension.class)の代わりに指定
class SpringJUnitWebConfigOnJunit5Test {

    @Autowired private ApplicationContext applicationContext;

    // Mockをインジェクションすることができる = @WebAppConfigurationが効いてる！
    @Autowired private MockServletContext mockServletContext;
    @Autowired private MockHttpSession mockHttpSession;
    @Autowired private MockHttpServletRequest mockRequest;

    @Test
    void defaultContextTest() {
        // ApplicationContextもWeb用のクラスが利用される = @WebAppConfigurationが効いてる！
        Assertions.assertEquals(GenericWebApplicationContext.class, applicationContext.getClass());
        Assertions.assertNotNull(mockServletContext);
        Assertions.assertNotNull(mockHttpSession);
        Assertions.assertNotNull(mockRequest);
        Assertions.assertEquals(1, applicationContext.getBeansOfType(MessageSource.class).size());
    }

    @Configuration
    static class LocalTestContext {}

}

@EnabledIfと@DisabledIfを試す

@EnabledIfは「指定した条件を充す（SpELで指定したExpressionの結果がtrueになる）場合にテストを実行すること」を、@DisabledIfは「条件を充す時にテストをスキップすること」を示すアノテーションで、クラスレベルとメソッドレベルの両方に指定することができます。

本エントリーでは、OSがMacなら行うテストとスキップするテストがあった際に、このアノテーションを利用してテストの実行制御を行ってみます。

package com.example.spring5testdemo;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.junit.jupiter.DisabledIf;
import org.springframework.test.context.junit.jupiter.EnabledIf;
import org.springframework.test.context.junit.jupiter.SpringJUnitConfig;

@SpringJUnitConfig
class XxxIfOnJunit5Test {

    @Test
    @EnabledIf("#{systemProperties['os.name'].toLowerCase().contains('mac')}")
    void enableOnMac() {
        // OSがMacの時にテストが行われる
        // ...
    }

    @Test
    @DisabledIf("#{systemProperties['os.name'].toLowerCase().contains('mac')}")
    void disableOnMac() {
        // OSがMacの時はテストがスキップされる（＝Mac以外の時はテストが行われる）
        // ...
    }

    @Configuration
    static class LocalTestContext {}

}

$ mvn test
...
Tests run: 2, Failures: 0, Errors: 0, Skipped: 1, Time elapsed: 0.128 sec - in com.example.spring5testdemo.XxxIfOnJunit5Test
...

特定のテストケースだけで使う条件(expression)なら上記のようにアドホックに記載してよいと思いますが、もし複数のテストで同じ条件を指定する必要があるなら、@EnabledIfまたは@DisabledIfをメタアノテーションにもつ合成アノテーションを作成する方がよいでしょう。

Macの時にテストを有効化するためのアノテーション

package com.example.spring5testdemo;

import org.springframework.test.context.junit.jupiter.EnabledIf;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@EnabledIf("#{systemProperties['os.name'].toLowerCase().contains('mac')}")
@Target({ElementType.TYPE, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface EnabledOnMac {
}

Macの時にテストをスキップするためのアノテーション

package com.example.spring5testdemo;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

import org.springframework.test.context.junit.jupiter.DisabledIf;

@DisabledIf("#{systemProperties['os.name'].toLowerCase().contains('mac')}")
@Target({ElementType.TYPE, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface DisabledOnMac {
}

テストコード

@Test
@EnabledOnMac // ★★★ 作成した合成アノテーションを指定して有効化の条件を共有
void enableOnMac() {
    // ...
}

@Test
@DisabledOnMac // ★★★ 作成した合成アノテーションを指定してスキップ条件を共有
void disableOnMac() {
    // ...
}

Spring TestContext Frameworkを使用したテストを平行実行できる

[SPR-5863] : Spring TestContext Framework(TCF)を使用したテストを平行実行できるようになります。 JUnit 5で試してみたかったのですが・・・平行実行を行う環境を「さく」っと作れなかったので、ここだけJUnit 4で試すことにしました・・・（悪しからず） なお、maven-surefire-pluginの依存ライブラリからJUnit 5用のライブラリを一時的に除外しておく必要があります。

Note:

本エントリーの中でも簡単に紹介しますが、平行実行時の制約や注意点については、「Spring Frameworkのリファレンス」をご覧ください。

    public void three() throws InterruptedException {
        TimeUnit.SECONDS.sleep(1);
        System.out.println("★★★★three★★★★" + Thread.currentThread().getName() + " :" + this);
        System.out.println("★★★★three★★★★" + Thread.currentThread().getName() + " :" + ac);
        System.out.println("★★★★three★★★★" + Thread.currentThread().getName() + " :" + ac.getBean(Foo.class));
        System.out.println("★★★★three★★★★" + Thread.currentThread().getName() + " :" + request);
    }

    @Configuration
    static class LocalTestContext {
        @Bean
        Foo foo() {
            return new Foo();
        }
    }

    static class Foo {}

}

このテストケースを実行すると、以下のようなログ（抜粋）がコンソール上に出力されます。

このログからわかることは・・・

• ３つのテストケースメソッドがそれぞれ異なるスレッド上で平行実行されている
• テストケースメソッド毎にテストケースクラスのインスタンスが生成されている
• インジェクションしているApplicationContextは各テストケースで共有している
• インジェクションしているMockオブジェクトは各テストケース毎にインスタンスが生成されている

ということです。
ポイントは・・・ApplicationContextが共有されているという点でしょう。平行実行ではテストが同時に実行されるため、DIコンテナで管理しているオブジェクトの状態を更新するようなテストケースがあると、別のテストケースの実行結果に影響を与える可能性があります。また、TCFを使ったテストに限ったことではありませんが、外部リソース（データベース、ファイルなど）にアクセスするようなテストを平行実行すると、期待通りの実行結果にならないことがあります。
このように・・・平行実行できるか否か？は、アプリケーションやテストケースの作りに依存するので、安易に平行実行を取り入れると予期しないエラーが発生してしまうことがあるので注意が必要です。

テストの実行直前と実行直後に呼び出されるコールバックメソッドが追加される

[SPR-4365] : TestExecutionListenerインタフェースに、テストの実行直前と実行直後に呼び出されるコールバックメソッド(beforeTestExecutionとafterTestExecution)が追加されます。

本エントリーではJUnit 5を使用して、「JUnit本体の仕組みで提供している前後処理」と「Spring TestContext Framework(TCF)の仕組みで提供している前後処理」の順序性を紹介します。

ちなみに・・・TCFがデフォルトで提供しているTestExecutionListenerの実装クラスと併用したい場合は、マージモードを指定する必要があります。（おそらく、併用したいケースの方が多いと思います）

        mergeMode = TestExecutionListeners.MergeMode.MERGE_WITH_DEFAULTS) // mergeModeを変更（デフォのままだと置換されちゃう）
class TestExecutionListenerTest {
    // ...
}

MockHttpServletRequestにリクエストBODYを取得するメソッドが追加される

[SPR-14717] : MockHttpServletRequestにリクエストBODYにアクセスするためのメソッド(getContentAsByteArrayとgetContentAsString)が追加されます。この対応はこの後で説明する「MockMvc使用時のテスト結果にリクエストBODYが出力される 」を対応するために行われたものです。正直・・・このメソッドを個別に使うことはほとんどないと思うので、サンプルを交えた説明は割愛させていただきます。

MockMvc使用時のテスト結果にリクエストBODYが出力される

[SPR-14717] : MockMvc使用時のテスト結果をコンソールまたはログに出力する際(MockMvcResultHandlersのprintまたはlogメソッドを使用する際)に、リクエストBODYも出力されるようになります。

具体的に「何が」「どのように」出力されるのかを見てみましょう。
っとその前に・・・MockMvcを使うためにはspring-webmvcを依存ライブラリに追加する必要があります。

pom.xml

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-webmvc</artifactId>
</dependency>

依存ライブラリの追加が終わったら、テスト用のControllerとテストケースを作成します。

package com.example.spring5testdemo;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;

import java.util.List;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.*;

class MvcMockTest {

    private MockMvc mockMvc;

    @BeforeEach
    void setupMockMvc() {
        mockMvc = MockMvcBuilders.standaloneSetup(new WelcomeRestController())
                    .addFilter(new CharacterEncodingFilter(StandardCharsets.UTF_8.name()))
                .build();
    }

    @Test
    void test() throws Exception {
        mockMvc.perform(post("/post").contentType(MediaType.APPLICATION_FORM_URLENCODED)
            .content("foo=bar") // ★★★ ← これが出力されるようになる
            .param("foo", "baz")
        ).andExpect(
            status().isOk()
        ).andExpect(
            result -> Assertions.assertEquals("[baz, bar]", result.getResponse().getContentAsString())
            // content().string("[baz, bar]") // Hamcrestがクラスパス上にある場合はこんな書き方ができる
        ).andDo(
            print() // コンソール出力
        ).andDo(
            log() // ログ出力
        );
    }

    @RestController
    static class WelcomeRestController {
        @PostMapping("/post")
        String post(@RequestParam List<String> foo) {
            return foo.toString();
        }
    }

}

作成したテストを実行すると、コンソールやログファイルにテスト実行結果が出力されます。

ちなみに・・・print()やlog()を全てのテストケースに適用したい場合は、AbstractMockMvcBuilderに実装されているalwaysDoメソッドを使いましょう。

@BeforeEach
void setupMockMvc() {
    mockMvc = MockMvcBuilders.standaloneSetup(new WelcomeRestController())
                .addFilter(new CharacterEncodingFilter(StandardCharsets.UTF_8.name()))
            .alwaysDo(print()) // こちらに移動
            .alwaysDo(log()) // こちらに移動
            .build();
}

MockMvc使用時の「リダイレクト先URL」と「フォワード先URL」の検証時にURIテンプレートが使える

[SPR-14790] : MockMvc使用時の「リダイレクト先URL」と「フォワード先URL」を検証する際に、期待値にURIテンプレートを指定できるようになります。（個人的には「フォワード先URL」の方はあまり使う機会がない気がしています。）

package com.example.spring5testdemo;

import java.nio.charset.StandardCharsets;

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.springframework.stereotype.Controller;
import org.springframework.test.web.servlet.MockMvc;

class MvcMockTransitionTest {

    private MockMvc mockMvc;

    @BeforeEach
    void setupMockMvc() {
        mockMvc = MockMvcBuilders.standaloneSetup(new TransitionController())
                    .addFilter(new CharacterEncodingFilter(StandardCharsets.UTF_8.name()))
                .build();
    }

    @Test
    void testRedirect() throws Exception {
        mockMvc.perform(get("/redirect/{id}", 1))
        .andExpect(
            status().isFound()
        ).andExpect(
            redirectedUrl("/transition/redirect/{id}", 1) // ★★★ リダイレクト時のURL検証
        );
    }

    @Test
    void testForward() throws Exception {
        mockMvc.perform(get("/forward/{id}", 1))
            .andExpect(
                status().isOk()
            ).andExpect(
            forwardedUrl("/transition/forward/{id}", 1) // ★★★ フォワード時のURL検証
        );
    }

    @Controller
    static class TransitionController {
        @GetMapping("/redirect/{id}")
        String redirect(@PathVariable int id) {
            return "redirect:/transition/redirect/{id}";
        }
        @GetMapping("/forward/{id}")
        String forward(@PathVariable int id) {
            return "forward:/transition/forward/" + id; // 個人的にこういうコードは基本的に書かないけど・・・（サンプルなので・・・）
        }
    }

}

XMLUnitのサポートバージョンが2.3になる

[SPR-14043] : XMLの検証をサポートするライブラリであるXMLUnitのサポートバージョンが2.3になります（本エントリーで紹介するサンプルコードは2.0.0でも動きました）。変更内容をみると2.x系からは検証用メソッド(assertXxx)のかわりにHamcrestのMatcherが提供されるようになったようです。
Spring Testでは、MockMvc使用時の処理結果を検証するコンポーネントの中でXMLUnitに依存しているものがあります。

XMLUnitに依存している機能を利用する場合は、以下のようにXMLUnitを依存ライブラリに加える必要があります。

pom.xml

<dependency>
  <groupId>org.xmlunit</groupId>
  <artifactId>xmlunit-core</artifactId>
  <version>2.3.0</version>
  <scope>test</scope>
</dependency>

package com.example.spring5testdemo;

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.filter.CharacterEncodingFilter;

import java.nio.charset.StandardCharsets;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

class XmlunitTest {

    private MockMvc mockMvc;

    @BeforeEach
    void setupMockMvc() {
        mockMvc = MockMvcBuilders.standaloneSetup(new XmlRestController())
            .addFilter(new CharacterEncodingFilter(StandardCharsets.UTF_8.name()))
            .alwaysDo(log())
            .build();
    }

    @Test
    void test() throws Exception {
        mockMvc.perform(get("/get"))
        .andExpect(
            status().isOk()
        ).andExpect(
            content().xml("<root><a>test</a></root>") // ★★★ XML文書として評価する(＝スペースや改行の違いは差分として扱われない)
        );
    }

    @RestController
    static class XmlRestController {
        @GetMapping("/get")
        String get() {
            return "<root> <a>test</a> </root>";
        }
    }

}

Note:

実際の検証処理はXmlExpectationsHelperに委譲しているので、MockMvc以外のところでも同等の検証を行うことが可能です。

まとめ

今回は、Test関連の主な変更点を紹介しました。やはり・・JUnit 5のサポートが最大の目玉ですね。JUnit 5はJUnit 4のことをJUnit Vintage(= Not後ろ向きな表現)としているところが個人的には好感がもてますw 名前の話だけではなく、「JUnit 5で書かれたテストケース」と「JUnit 4で書かれたテストケース」を同時に実行できるのも魅力的です（過去の成果物をそのまま移行できる！！＝余力ができたらコードレベルでJUnit 5化すればいい！！）。Maven(maven-surefire-plugin)なら・・・

pom.xml

<plugin>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.19.1</version>
  <dependencies>
    <dependency>
      <groupId>org.junit.platform</groupId>
      <artifactId>junit-platform-surefire-provider</artifactId>
      <version>${junit-platform.version}</version>
    </dependency>
    <dependency>
      <groupId>org.junit.jupiter</groupId>
      <artifactId>junit-jupiter-engine</artifactId>
      <version>${junit-jupiter.version}</version>
    </dependency>
    <!-- ★★★ ↓ これを追加すればJUnit 5とJUnit 4で書かれたテストケースを同時にテストできる -->
    <dependency>
      <groupId>org.junit.vintage</groupId>
      <artifactId>junit-vintage-engine</artifactId>
      <version>4.12.0-M4</version>
    </dependency>
  </dependencies>

ってな感じにすればOKです。

Spring Frameworkの話から脱線してしまいましたが・・・ アプリケーション開発を行う上でテストは非常に大事な要素であり、Spring Frameworkもテストコードを作るための支援機能を豊富に提供してくれています。（目先のスケジュールを守るために）「時間がないからテストは後回し（＝動作確認をテストと言い張る）！」「（打鍵の）結合試験でやるから単体テストしない！」とか説得力０な事を言う人がいますが、最終的に誰も得しないので、スケジュールを見直して（調整して）テストコードをちゃんと作るようにしましょう。
Springを使ってアプリケーションを作る場合は、「Spring Frameworkのリファレンス(テスト編)」を一読することをオススメします。（けっこう量ありますがw）
次回は、Reactive Programing ModelのWebフレームワーク（WebFlux）を紹介する予定です。

付録：Spring Boot 2.0でJUnit 5を使う方法

ここでは、Spring Boot 2.0でJUnit 5(+JUnit 4)を使う（共存する）方法を紹介します。基本的には本エントリーで説明したことをSpring Bootアプリケーションに適用するだけです。

• Spring Bootプロジェクトの作成

$ curl -s https://start.spring.io/starter.tgz\
  -d name=test-demo\
  -d artifactId=test-demo\
  -d baseDir=test-demo\
  -d bootVersion=2.0.0.M1\
  | tar -xzvf -

• pom.xmlを修正

• JUnit 5用のテストケースクラス(空のテストケース)の作成

package com.example.testdemo;

import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit.jupiter.SpringExtension;

@ExtendWith(SpringExtension.class)
@SpringBootTest
class TestDemoApplicationUsingJUnit5Tests {

    @Test
    void contextLoads() {
    }

}
