Should I use a seperate beans.xml configuration for instantiating objects in my unit tests?

Here's my Beans.xml for my application

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://ift.tt/GArMu6"
    xmlns:xsi="http://ift.tt/ra1lAU"
    xsi:schemaLocation="http://ift.tt/GArMu6
    http://ift.tt/QEDs1e">


        <bean id="myRoom" class="org.world.hello.Room">
            <property name="bottleCounter">
                <bean id="myBottleCounter" class="org.world.hello.BottleCounter" />
            </property>
            <property name="numBottles" value="10"></property>

        </bean>    
</beans>

It's one Room bean that has a BottleCounter bean as a property.

Now, I want to write a unit testing for BottleCounter.

public class BottleCounterTest {

    ApplicationContext context; 

    @Before
    public void setUp()
    {
        context = new ClassPathXmlApplicationContext("Beans.xml");      
    }

    @Test
    public void testOneBottle() {

        BottleCounter bottleCounter = (BottleCounter) context.getBean("myBottleCounter");

        assertEquals("1 bottles of beer on the wall1 bottles of beer!", bottleCounter.countBottle(1));
    }

}

But I can't directly reference myBottleCounter as it's a inner bean? And gives me No bean named 'myBottleCounter' is defined.

So should instead, I be defining my test beans in a seperate xml?

eg.

testBeans.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://ift.tt/GArMu6"
    xmlns:xsi="http://ift.tt/ra1lAU"
    xsi:schemaLocation="http://ift.tt/GArMu6
    http://ift.tt/QEDs1e">


        <bean id="testRoom" class="org.world.hello.Room">
            <property name="bottleCounter">
                <bean id="myBottleCounter" class="org.world.hello.BottleCounter" />
            </property>
            <property name="numBottles" value="3"></property>

        </bean>

        <bean id="testBottleCounter" class="org.world.hello.BottleCounter" />



</beans>

BottleCounterTest.java

public class BottleCounterTest {

    ApplicationContext context; 

    @Before
    public void setUp()
    {
        context = new ClassPathXmlApplicationContext("testBeans.xml");      
    }

    @Test
    public void testOneBottle() {

        BottleCounter bottleCounter = (BottleCounter) context.getBean("testBottleCounter");

        assertEquals("1 bottles of beer on the wall1 bottles of beer!", bottleCounter.countBottle(1));
    }

}
