Spring not autowiring in unit tests with JUnit
java, junit, spring
Solution
Add something like this to your root unit test class:
@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration
This will use the XML in your default path. If you need to specify a non-default path then you can supply a locations property to the ContextConfiguration annotation.

Problem
I test the following DAO with JUnit: ``` @Repository public class MyDao { @Autowired private SessionFactory sessionFactory; // Other stuff here } ``` As you can see, the sessionFactory is autowired using Spring. When I run the test, sessionFactory remains null and I get a null pointer exception. This is the sessionFactory configuration in Spring: ``` <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation"> <value>classpath:hibernate.cfg.xml</value> </property> <property name="configurationClass"> <value>org.hibernate.cfg.AnnotationConfiguration</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${jdbc.dialect}</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> </bean> ``` What's wrong? How can I enable autowiring for unit testings too? Update: I don't know if it's the only way to run JUnit tests, but note that I'm running it in Eclipse with right-clicking on the test file and selecting "run as"->"JUnit test"
