Writing integration tests with Spring

Spring provides the module or utility library for integration tests. The following are the steps to write JUnit tests using the Spring transaction management API and SpringJUnit4ClassRunner:

1. Spring supports XML-based configuration and wiring beans. Create an XML file named integration.xml in the integration source package. Modify the XML file and define the dataSource, transactionManager, and JdbcTemplate Spring beans. The following is the XML body:

   <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
    
     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
       <property name="driverClassName" value="org.apache.derby.jdbc.EmbeddedDriver"/>
       <property name="url" value="jdbc:derby:derbyDB;create=true"...
