Configuring data access layer properties files in Spring Integeration testing environment

I am setting up test environment for my Spring web application. I use .properties files and Environment to configure my persistence layer properties as shown below(I have skipped code for brevity):

PersistenceConfig.java

@PropertySources({
@PropertySource(value= "classpath:/com/hp/properties/persistence/mysqldb.properties"),
@PropertySource(value = "classpath:/com/hp/properties/persistence/hibernate.properties")})
public class PersistenceConfig {

@Autowired
Environment env;

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(){
    LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource(dataSource());
    em.setPackagesToScan(new String[] {"com.hp.model.entity"});

    JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    em.setJpaVendorAdapter(vendorAdapter);
    em.setJpaProperties(hibernateProperties());

    return em;
}

private Properties hibernateProperties(){
    Properties properties = new Properties();
    properties.setProperty("hibernate.dialect", env.getRequiredProperty("hibernate.dialect.mysql"));
    properties.setProperty("hibernate.show_sql", env.getRequiredProperty("hibernate.showsql"));
    properties.setProperty("hibernate.format_sql", env.getRequiredProperty("hibernate.formatsql"));
    return properties;
}
}

I am creating my test classes using Spring's WebApplicationContext as shown below:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes={ApplicationConfig.class})
@WebAppConfiguration
@TestPropertySource(value = {"classpath:/com/hp/properties/persistence/mysqldb.properties", 
    "classpath:/com/hp/properties/persistence/hibernate.properties"})
public class PatientServiceTest {

MockMvc mockMvc;

@Autowired
WebApplicationContext webApplicationContext;

@Before
public void setUp(){
    mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
}

@Test
public void testForDependentBeans(){
    Assert.assertThat(webApplicationContext.containsBean("patientRepository"), Matchers.is(true));
}

}

But as I run the test I get an error about the intialization of PersistnceConfig as hibernate.properties is not found. I have also tried copying these files from src/main/java to src/test/java and add @TestPropertySource to explicitly provide the properties file. Yet I am getting the same error. Below is the stack trace if it helps.

Also, how can I load different properties file specific to test environment in Spring integeration testing than used by my production.
