如何在SpringFramework 2中将dataSource注入到jUnit以进行集成测试

Question

I have the following dataSource defined in my spring-beans.xml file which I use in order to connect in my remote database :

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/sample"/>
    <property name="username" value="root"/>
    <property name="password" value="root"/>

</bean>

I am building a couple of jUnit integration tests that I want to run. Some of the functions that get called from these tests use this datasource in order to access my database. When I deploy my project the dataSource is injected according to beans configuration that I have done.

For these tests that will run independently of the web application how can I inject this dataSource in order to access the database ?

I use the SpringFramework 2.5.6 version and jUnit4 for my tests.

Integration test with Spring

Sample jUnit Integration test

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "spring-beans.xml")
public class MyIntegrationTest {

   @Autowired
   DataSource dataSource;

}

Database testing with Unitils

Unitils greatly reduces this complexity, making database testing easy and maintainable.

Unitils offers features for unit testing when working with Spring .

public abstract class BaseDAOTest extends UnitilsJUnit4 {

    @TestDataSource
    private DataSource dataSource;

    @Before    
    public void initializeDao() {
        BaseDAO dao = getDaoUnderTest();
        dao.setDataSource(dataSource);
    }

    protected abstract BaseDAO getDaoUnderTest();
}
