JUnit Tests against a class that uses Tomcat Connection Pools

I've got a class that normally executes from within Tomcat which uses a MySQL database connection pool..
I'd like to set up some JUnit tests to test this external to Tomcat.  

Currently, if I execute the test, I get the following exception:
ERROR: Unable to get a connection from jdbc/portalDb
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial
        at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
        at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
        at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
        ...

I've read up on the jndi.properties file.  But the examples are horrible, I'm not sure what to set the java.naming.factory.initial property to, let alone how to define a connection to the MySQL database.  
How do I get these tests to work?

Thanks.

jndi.properties file should be there on the classpath.

Error message indicates that you need to specify the type and location of your jndi store.   You may need to create a jndi.properties file and to specifying environment Properties in it:
java.naming.factory.object=xxxx.yyy.zzzz
java.naming.factory.state=xxxx.yyy.zzzz
java.naming.factory.initial=xxxx.yyy.zzzz
....
Then you have to make sure your jndi.properties file is in your CLASSPATH.

If you have permission to temporarily change code, a simple way is to change dataSource connection to:
Class.forName("org.gjt.mm.mysql.Driver");
String connectionURL = "jdbc:mysql://localhost:3306/mydatabase";
Connection connection = DriverManager.getConnection(connectionURL, "root", "password");

Thanks to those who responded.  I did some further digging and found a similar situation that someone else had.  I ended up creating a skeleton class that implements javax.naming.spi.InitialContextFactory and used that to create a connection to the database.  It works great and doesn't intrude on the source code.  

jndi.properties basically has one line:
java.naming.factory.initial=com.sungard.sase.portal.webapp.db.pool.ContextFactory

which points to my class.
