JUnit Testing with Spring MVC : Initialization error

This is my first try with JUnit testing and Spring MVC. I have made a test configuration class for beans and one test class for controller. While executing the test, there is test failure which says Initialization error and no class definition found error. Following is my TestBeanConfig.java file

package com.mkyong.controller;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.test.context.ContextConfiguration;
@Configuration
@ComponentScan(basePackages = "com.mkyong.controller")
public class TestBeanConfig {

    @Bean
    MultiplicationService multiplicationservice() {
    return new MultiplicationService();
    }

    @Bean
    NumberDAO numberDao() {
    NumberDAO numberdao =new NumberDAO();
    return numberdao;
    }
}

and MultiplicationServiceTest.java

package com.mkyong.controller;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes={TestBeanConfig.class})
public class MultiplicationServiceTest {

    @Autowired
    private MultiplicationService multiplytestobject;

    MockMvc mockMvc ;

    @Autowired
    private WebApplicationContext wac;

    public MultiplicationServiceTest() {

    }

    public MultiplicationService getMultiplytestobject() {
        return multiplytestobject;
    }

    public void setMultiplytestobject(MultiplicationService multiplytestobject) {
        this.multiplytestobject = multiplytestobject;
    }

    @Before
    public void setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    @Test
    public void testHandleMultiply() throws Exception {
    mockMvc.perform(post("/multiply").param("number1","7").param("number2","7"))
    .andExpect((model().attribute("result", "49")))
    .andExpect(redirectedUrl("/multiply.jsp"));
    }

}

Trace of error:

Tests in error: 
  initializationError(com.mkyong.controller.MultiplicationServiceTest): Failed to instantiate [org.springframework.test.context.web.WebDelegatingSmartContextLoader]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: javax/servlet/ServletContext

Add this to maven pom.xml dependencies:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>

This should provide classes project's searching for.

Let me know if it helps you out.
