How do I mock the JBoss 7 JTA transaction manager in JUnit?

[Dave Alvarado]

Hi,

I'm building a WAR using Spring 3.1.1.RELEASE, Hibernate 4.1.0.Final, JPA 2.0, and deploying to JBoss 7.1.1.Final. I'm noticing some errors that occur in my JBoss environment that don't occur in my unit tests and I want to eliminate a couple of factors. Is there a way to mock the JBoss transaction manager when running Spring JUnit tests? I use this application context when I deploy my application:

	<!-- JNDI name for EntityManagerFactory is defined in src/main/resources/META-INF/persistence.xml -->
	<jee:jndi-lookup jndi-name="java:jboss/springboard/myclientpersistence"
		id="entityManagerFactory" expected-type="javax.persistence.EntityManagerFactory" />

	<bean id="entityManager" class="org.springframework.orm.jpa.support.SharedEntityManagerBean">
		<property name="entityManagerFactory" ref="entityManagerFactory" />
	</bean>

	<jee:jndi-lookup jndi-name="java:jboss/datasources/MySqlDS" id="dataSource" expected-type="javax.sql.DataSource"/>

	<tx:jta-transaction-manager />

	<tx:annotation-driven />

but in my JUnit environment, I use a different context:

	<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
                <property name="driverClassName" value="org.h2.Driver" />
                <property name="url" value="jdbc:h2:~/myclientclient-test" />
                <property name="username" value="" />
                <property name="password" value="" />
	</bean>
    
	<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
        </property>
        <property name="persistenceXmlLocation" value="classpath:META-INF/test-persistence.xml"/>
        <property name="persistenceUnitName" value="testingDatabase"/>
        <property name="dataSource" ref="dataSource"/>
    </bean>

	<bean id="sharedEntityManager" class="org.springframework.orm.jpa.support.SharedEntityManagerBean">
       <property name="entityManagerFactory" ref="entityManagerFactory"/>
    </bean>

	<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory"/>
    </bean>

	<tx:annotation-driven />

	<jdbc:embedded-database id="embedded" type="H2"/> 
	<jdbc:initialize-database data-source="dataSource">
		<jdbc:script location="classpath:db-test-data.sql"/>	
	</jdbc:initialize-database>

I would like my tests to mirror as closely as possible what will happen when I deploy. Thanks, -
