How do I mock a TransactionManager in a JUnit test, (outside of the container)?

I'm using Spring 3.1.0.RELEASE, JUnit 4.8.1, and ultimately deploying my application to a JBoss 4.2 server (I know, I know). As part of setting up my unit test, I have this in my Spring test application context ...

<bean id="transactionManager"  
    class="org.springframework.transaction.jta.JtaTransactionManager">
        <property name="userTransactionName">
        <value>UserTransaction</value>
    </property> 
</bean>

Of course, right now this fails because there is nothing bound to the JNDI name, "UserTransaction." How do I mock a transaction manager? I'm using the org.mockejb framework but an open to any suitable mocking frameworks.

You can also use Mockito:

PlatformTransactionManager manager = mock(PlatformTransactionManager.class);
