ArquillianチュートリアルのJPAを使ったテストを走らせるところをやってみる

Posted on Saturday Jan 25, 2014 at 02:29PM in Technology

Arquillianチュートリアルのリモートコンテナでテストを走らせるところをやってみるの続きです。JPAを使ったテストを走らせるところをやってみます。今回も基本的にはチュートリアル[1]なぞるだけです。

環境

  • JBoss AS 7.1.1.Final
  • Eclipse Kepler SR1
  • Apache Maven 2.2.1 (r801777; 2009-08-07 04:16:01+0900)
  • Apple JDK6u65
  • OS X 10.9.1

準備

チュートリアルにはGlassFishでテストを走らせる方法についても書いてありますが、ここではJBossで必要なものだけ用意します

何を作るか

この画像で選択されている4つのリソースを作ります

Game.java (エンティティクラス)

package org.arquillian.example;

import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

@Entity
public class Game implements Serializable {
    private Long id;
    private String title;

    public Game() {}

    public Game(String title) {
        this.title = title;
    }

    @Id @GeneratedValue
    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    @NotNull
    @Size(min = 3, max = 50)
    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    @Override
    public String toString() {
        return "Game@" + hashCode() + "[id = " + id + "; title = " + title + "]";
    }
}

GamePersistenceTest.java (テストクラス)

このチュートリアルではEntityManagerを叩いているのはこのテストクラスだけです。本当はJPAを使ったEJBのテストをしたいところですが、とりあえずこれでやってみます

package org.arquillian.example;

import java.util.List;
import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.transaction.UserTransaction;
import org.junit.Before;
import org.junit.After;
import org.junit.Test;
import java.util.Arrays;
import java.util.Collection;
import java.util.HashSet;
import java.util.Set;
import org.junit.Assert;
import org.jboss.arquillian.container.test.api.Deployment;
import org.jboss.arquillian.junit.Arquillian;
import org.jboss.shrinkwrap.api.Archive;
import org.jboss.shrinkwrap.api.ShrinkWrap;
import org.jboss.shrinkwrap.api.asset.EmptyAsset;
import org.jboss.shrinkwrap.api.spec.WebArchive;
import org.junit.runner.RunWith;

@RunWith(Arquillian.class)
public class GamePersistenceTest {
    @Deployment
    public static Archive<?> createDeployment() {
        return ShrinkWrap.create(WebArchive.class, "test.war")
            .addPackage(Game.class.getPackage())
            .addAsResource("test-persistence.xml", "META-INF/persistence.xml")
            .addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml")
            .addAsWebInfResource("jbossas-ds.xml");
    }

    private static final String[] GAME_TITLES = {
        "Super Mario Brothers",
        "Mario Kart",
        "F-Zero"
    };

    @PersistenceContext
    EntityManager em;

    @Inject
    UserTransaction utx;

    @Before
    public void preparePersistenceTest() throws Exception {
        clearData();
        insertData();
        startTransaction();
    }

    private void clearData() throws Exception {
        utx.begin();
        em.joinTransaction();
        System.out.println("Dumping old records...");
        em.createQuery("delete from Game").executeUpdate();
        utx.commit();
    }

    private void insertData() throws Exception {
        utx.begin();
        em.joinTransaction();
        System.out.println("Inserting records...");
        for (String title : GAME_TITLES) {
            Game game = new Game(title);
            em.persist(game);
        }
        utx.commit();
        // clear the persistence context (first-level cache)
        em.clear();
    }

    private void startTransaction() throws Exception {
        utx.begin();
        em.joinTransaction();
    }

    @After
    public void commitTransaction() throws Exception {
        utx.commit();
    }

    @Test
    public void shouldFindAllGamesUsingJpqlQuery() throws Exception {
        // given
        String fetchingAllGamesInJpql = "select g from Game g order by g.id";

        // when
        System.out.println("Selecting (using JPQL)...");
        List<Game> games = em.createQuery(fetchingAllGamesInJpql, Game.class).getResultList();

        // then
        System.out.println("Found " + games.size() + " games (using JPQL):");
        assertContainsAllGames(games);
    }

    private static void assertContainsAllGames(Collection<Game> retrievedGames) {
        Assert.assertEquals(GAME_TITLES.length, retrievedGames.size());
        final Set<String> retrievedGameTitles = new HashSet<String>();
        for (Game game : retrievedGames) {
            System.out.println("* " + game);
            retrievedGameTitles.add(game.getTitle());
        }
        Assert.assertTrue(retrievedGameTitles.containsAll(Arrays.asList(GAME_TITLES)));
    }
}

jbossas-ds.xml (データソース定義)

データソース定義をこのファイルに書いておけば、テスト実行する度に一時的にデータソース定義を行ってくれます。APサーバ側のコンソールをいじってデータソース定義をやる必要はありません。これは便利。

本当はPostgreSQLあたりを使ってリアルにレコードを確認したいところですが、簡単のためとりあえずチュートリアル通りに標準搭載のH2を使ってインメモリデータベースを使います

<?xml version="1.0" encoding="UTF-8"?>
<datasources xmlns="http://www.jboss.org/ironjacamar/schema"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.jboss.org/ironjacamar/schema
        http://docs.jboss.org/ironjacamar/schema/datasources_1_0.xsd">
    <datasource enabled="true"
        jndi-name="jdbc/arquillian"
        pool-name="ArquillianEmbeddedH2Pool">
        <connection-url>jdbc:h2:mem:arquillian;DB_CLOSE_DELAY=-1</connection-url>
        <driver>h2</driver>
    </datasource>
</datasources>

test-persistence.xml (永続化コンテキスト定義)

JTAトランザクションのJavaEEなJPAの定義ですね。JavaSEのと違ってエンティティクラス名の列挙は必要ありません。良い。

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://java.sun.com/xml/ns/persistence
        http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="test">
        <jta-data-source>jdbc/arquillian</jta-data-source>
        <properties>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.show_sql" value="true"/>
        </properties>
    </persistence-unit>
</persistence>

備考

特に問題なさげですね。しかも速い。クラスの数も少なくアプリケーションアーカイブのサイズも小さいので当然かもしれませんが3〜4秒です。これならJPAのマニアックな機能を使った複雑な機能の実装とテストも怖くないですね。

というか本家のチュートリアル[1]がよくできてて日本語訳も読みやすいので読みましょう。

ちなみにチュートリアルにも書かれていますが埋め込みモードではJPAを使ったテストは動かないそうです。ただし埋め込みGlassFishは可。
