arquillian-embedded 進行EJB測試

arquillian測試框架具有普通測試框架無法做到的是功能，對容器依賴的EJB測試，當然這個測試過程是要比普通的測試要稍微複雜一些

一、基於測試框架內置容器和內置數據庫(derby)的測試

此配置在官網有詳細的示例，此處就不再重複，請參考http://arquillian.org/guides/

二、配置自己的數據庫爲測試數據庫(使用db2)

1、配置pom.xml (使用openjpa作爲項目的jpa實現)

由於此測試框架有自己的一套JavaEE的實現jar包，所以會造成與工程內部的jsf和javaee6 api等衝突，使用測試框架時不能啓用此jar包（通過配置profile，可參考arquillian官網示例介紹）。

	<profile>
		<id>dev</id>
		<activation>
			<activeByDefault>false</activeByDefault>
		</activation>
		<dependencies>
			<dependency>
				<groupId>org.apache.openjpa</groupId>
				<artifactId>openjpa-all</artifactId>
				<version>2.1.1</version>
			</dependency>
			<dependency>
				<groupId>javax</groupId>
				<artifactId>javaee-web-api</artifactId>
				<version>6.0</version>
				<type>jar</type>
				<scope>provided</scope>
			</dependency>
			<dependency>
				<groupId>javax.faces</groupId>
				<artifactId>jsf-api</artifactId>
				<version>2.1</version>
				<type>jar</type>
				<scope>provided</scope>
			</dependency>
		</dependencies>
	</profile>

配置測試框架需要的基礎jar包(亦可參照官網介紹)

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.jboss.arquillian</groupId>
				<artifactId>arquillian-bom</artifactId>
				<version>1.0.0.Final</version>
				<scope>import</scope>
				<type>pom</type>
			</dependency>
		</dependencies>
	</dependencyManagement>

	<dependency>
		<groupId>junit</groupId>
		<artifactId>junit</artifactId>
		<version>4.8.1</version>
		<scope>test</scope>
	</dependency>
	<!-- Arquillian JUnit -->
	<dependency>
		<groupId>org.jboss.arquillian.junit</groupId>
		<artifactId>arquillian-junit-container</artifactId>
		<scope>test</scope>
	</dependency>

配置glassfish-embedded (放到單獨的profile中)，db2的jar包不包含在maven庫中，因此需要在本地進行配置，也可以不在pom中加入，在build path中添加

	<profile>
		<id>arquillian-glassfish-embedded</id>
		<activation>
			<activeByDefault>true</activeByDefault>
		</activation>
		<dependencies>
			<dependency>
				<groupId>org.jboss.arquillian.container</groupId>
				<artifactId>arquillian-glassfish-embedded-3.1</artifactId>
				<version>1.0.0.CR3</version>
				<scope>test</scope>
			</dependency>
			<dependency>
				<groupId>org.glassfish.main.extras</groupId>
				<artifactId>glassfish-embedded-all</artifactId>
				<version>3.1.2</version>
				<scope>provided</scope>
			</dependency>
			<!-- OpenJPA -->
			<dependency>
				<groupId>org.apache.openjpa</groupId>
				<artifactId>openjpa-all</artifactId>
				<version>2.1.1</version>
			</dependency>
			<dependency>
				<groupId>db2jcc</groupId>
				<artifactId>db2jcc</artifactId>
				<version>9.7</version>
			</dependency>
			<dependency>
				<groupId>db2jcc</groupId>
				<artifactId>db2jcc_license_cu</artifactId>
				<version>9.7</version>
			</dependency>
		</dependencies>
	</profile>

2、配置arquillian.xml (此配置文件爲測試框架默認讀取的配置文件)

配置glassfish的資源文件的路徑

<?xml version="1.0" encoding="UTF-8"?>
<arquillian xmlns="http://jboss.org/schema/arquillian"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="
        http://jboss.org/schema/arquillian
        http://jboss.org/schema/arquillian/arquillian_1_0.xsd">
	<container qualifier="glassfish-embedded" default="true">
		<configuration>
			<property name="resourcesXml">
                src/test/resources/resources-glassfish-embedded/glassfish-resources.xml
            </property>
		</configuration>
	</container>
</arquillian>

.../glassfish-resources.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE resources PUBLIC
    "-//GlassFish.org//DTD GlassFish Application Server 3.1 Resource Definitions//EN"
    "http://glassfish.org/dtds/glassfish-resources_1_5.dtd">
<resources>
	<jdbc-resource pool-name="ArquillianEmbeddedH2Pool"
		jndi-name="jndi/name" />
	<jdbc-connection-pool driver-classname="com.ibm.db2.jcc.DB2Driver"
		res-type="java.sql.Driver" name="ArquillianEmbeddedH2Pool">
		<property name="URL"
			value="jdbc:db2://IP:Port/dbName:driverType=4;"></property>
		<property name="user" value="db2inst1"></property>
		<property name="password" value="yourPassword"></property>
	</jdbc-connection-pool>
</resources>

3、persistence.xml 普通的jap配置以外需要加上RuntimeUnenhancedClasses 支持

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
	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_1_0.xsd">
	<persistence-unit name="BASE" transaction-type="JTA">
		<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
		<jta-data-source>jndi/name</jta-data-source>
		<properties>
			<property name="openjpa.RuntimeUnenhancedClasses" value="supported" />
			<property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)" />
		</properties>
	</persistence-unit>
</persistence>

4、測試方法

@RunWith(Arquillian.class)
public class TestServiceTest {
	@Deployment
	public static Archive<?> createDeployment() {
		WebArchive webInfResource = ShrinkWrap
				.create(WebArchive.class, "test.war")
				.addPackages(true, TestService.class.getPackage(), TestTable.class.getPackage())
				.addAsResource("META-INF/persistence.xml")
				.addAsWebInfResource(EmptyAsset.INSTANCE, "beans.xml");
		System.out.println("webInfResource:" + webInfResource);
		return webInfResource;
	}

	@EJB
	private TestService ts;

	@Test
	public void test() {
		ts.add();
		ts.select();
	}
}
