Re: Unable to use Junit 4 annotations

[Ryan de Laplante]

It turns out I have to tell Spring that it is using JUnit 4 by 
annotating my class:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"file:src/test/resources/META-INF/applicationContext.xml"})
public class SettingsDAOTest extends AbstractJpaTests {
Before the AbstractJpaTests superclass set everything up and injected 
what I needed into my test class.  Now all of that is gone, so I had to 
add the @ContextConfiguration annotation and @Autorwired to inject the 
DAO.   Now it doesn't recognize the entity I am trying to merge with JPA. 

I also found out that  @RunWith(SpringJUnit4ClassRunner.class)  only 
works with Junit 4.4 and newer.  But, surefire maven2 plugin causes 
trouble when using Junit 4.5 so you have to downgrade to 4.4:

http://jira.springframework.org/browse/SPR-5145


Too much trouble.  I'm going to use JUnit 3 style configs for this class 
so that AbstractJpaTest actually works.

So this must be a spring problem.

Hi,

My junit tests work if I prefix test method names with the word 
test.  If I don't do that and rely on the @Test annotation then the 
test methods are not executed.

I have this in my POM:

<dependency>
   <groupId>junit</groupId>
   <artifactId>junit</artifactId>
   <version>4.5</version>
   <scope>test</scope>
</dependency>

and in my build section I have:

<plugins>
           <plugin>
               <artifactId>maven-compiler-plugin</artifactId>
               <version>2.0.2</version>
               <configuration>
                   <source>1.5</source>
                   <target>1.5</target>
               </configuration>
           </plugin>
           <plugin>
               <artifactId>maven-surefire-plugin</artifactId>
               <version>2.4.3</version>
               <configuration>
                   <includes>
                       <!-- Only execute test suites -->
                       <include>**/*TestSuite.java</include>
                   </includes>
               </configuration>
           </plugin>
       </plugins>

So I am using the latest version of surefire.  Any ideas why it's not 
using Junit 4?

Thanks,
Ryan
