JUnit struts 2.3.16 with Spring causing Unable to load bean org.apache.struts2.dispatcher.mapper.ActionMapper (globalActionMapper) exception

My JUnit is not working as expected. I am following this link Below is the my code:

StrutsTest.java:

package com.test.action;

import org.apache.struts2.StrutsSpringTestCase;
import org.junit.Assert;
import org.junit.Test;

import com.opensymphony.xwork2.ActionProxy;

public class StrutsTest extends StrutsSpringTestCase {

    public void testHomePage() {
        System.out.println("Inside the method!");

        ActionProxy actionProxy = getActionProxy("hello/index.action");

        System.out.println("Right here!");
        try {
            Assert.assertEquals("Two are equal", 0, 0);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }


    @Override
    protected String[] getContextLocations() {
        return new String[] { "classpath*:test-applicationContext.xml" };
    }

}

test-applicationContext.xml

Not sure what may be causing it. Can you provide any feedback? Also, I want to have a separate struts file for test. Is it possible to do that? if yes, How?
