Spring - unit tests

Question

I followed the instructions at " Unit Testing with Junit, Spring and Hibernate – Part 2 ".

I created my simple test class:

package com.bontade.tests.unit.models;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.SessionFactoryUtils;
import org.springframework.test.AbstractTransactionalDataSourceSpringContextTests;

import com.bontade.mvc.models.User;
import com.bontade.mvc.models.dao.implementations.UserDAOImplementation;

public class UserDAOTest extends
    AbstractTransactionalDataSourceSpringContextTests {

private UserDAOImplementation userDAO;
private SessionFactory sessionFactory;

/*
public UserDAOTest() {
    setDependencyCheck(false);
    setAutowireMode(AUTOWIRE_BY_NAME); 
}
*/

public void setUserDAO(UserDAOImplementation userDAO) {
    this.userDAO = userDAO;
}

public void setSessionFactory(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}

protected String[] getConfigLocations() {
    // classpath*:/src/test/java/com/bontade/tests/unit/models/test-spring-  config.xml
    return new String[] { "classpath*:/**/test-spring-config.xml" };
}

public void testSave() {
    String query = "SELECT COUNT(*) FROM User WHERE name = 'Mark'";
    int count = this.jdbcTemplate.queryForInt(query);
    assertEquals("A user already exists in the DB", 0, count);

    User user = new User();
    user.setId(null);
    user.setName("Mark");
    user.setGender("Man");
    user.setSurname("Surname");
    user.setPassword("X");

    userDAO.saveUser(user);

    // flush the session so we can get the record using JDBC template
    SessionFactoryUtils.getSession(sessionFactory, false).flush();

    count = jdbcTemplate.queryForInt(query);
    assertEquals("User was not found in the DB", 1, count);
}
}

My configuration file:

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

<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-2.5.xsd">

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="org.h2.Driver" />
    <property name="url"
        value="jdbc:h2:tcp://localhost/~/bontade_database_h2" />
    <property name="username" value="ab" />
    <property name="password" value="ab" />
</bean>

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.bontade.mvc.models.User</value>
        </list>
    </property>
</bean>

<bean id="transactionManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>

<bean id="userDAO"
    class="com.bontade.mvc.models.dao.implementations.UserDAOImplementation">
    <property name="sessionFactory" ref="sessionFactory" />
    <property name="transactionTemplate">
        <bean     class="org.springframework.transaction.support.TransactionTemplate">
            <property name="transactionManager" ref="transactionManager" />
        </bean>
    </property>
</bean>

Both files are placed inside the src/test/java directory in the com.bontade.tests.unit.models package. UserDAO and UserDAOImplementation are placed in the src/main/java directory.

I'm getting error like this:

Does anybody know the reason why?

UPDATE:

After reading @Ritesh's clue, I moved "test-spring-config.xml" into the src/test/resources directory and now I see a file in the target/test-classes folder, but I got a new error:

Does it mean that I don't have the required jars in my classpath?

Answer 1

The solution was to use

org.springframework.orm.hibernate3.LocalSessionFactoryBean

instead of

org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean
