Surefire is not picking up Junit 4 tests

Question

I cannot get Maven Surefire to execute my JUnit 4 tests even after I tried all the advices from another post.

My POM:

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>maven-test</groupId>
  <artifactId>maven-test</artifactId>
  <version>0.0.1-SNAPSHOT</version>

  <dependencies>
    <dependency>
      <groupId>org.junit</groupId>
      <artifactId>com.springsource.org.junit</artifactId>
      <version>4.4.0</version>
      <scope>test</scope>
    </dependency>  
  </dependencies>

  <build> 
    <plugins> 
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.5</source>
          <target>1.5</target>
        </configuration>
      </plugin>  
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.5</version>
      </plugin> 
    </plugins>
  </build> 
</project>

My Test:

public class TestSimple {

 public void testSurePass()
 {
  int x = 1;
  Assert.assertEquals(1, x);
 }

 @Test
 public void surePass()
 {
  int x = 1;
  Assert.assertEquals(1, x);  
 }
}

Surefire picked up testSurePass, but never saw surePass. I tried mvn -X:

Surefire 2.5 adds junit-3.8.1 to its test classpath automatically. Although junit-4.4.0 is also added (not to surefire test classpath, but Test Classpath), junit-3.8.1 seems to take precedence. Maven's surefire-api project has a dependency on junit-3.8.1 according to http://maven.apache.org/surefire/surefire-providers/dependencies.html.

Am I missing some configuration here?

Answer 1

Surefire has a junit-version artifact detection mechanim that is being fooled by you using the junit artifact packaged by springsource. You need to set the junitartifactname parameter to org.junit:com.springsource.org.junit

Answer 2

I'm lost, I cannot reproduce your problem. But there is indeed a Jira issue (see EBR-220) explaining that you need to add the following to the surefire configuration when using the JUnit artifact packaged by SpringSource:

<junitArtifactName>org.junit:com.springsource.org.junit</junitArtifactName>

thanks Pascal! since krosenvold replied first with the same solution, i placed my check next to his. – Haywood

@Candy No problem, that's perfectly appropriate actually. I just posted this answer for the Jira reference. – Canonicals

Answer 3

It's possible to use JUnit 4.x with maven 1.x :

* add Junit 4.X in your dependencies
* Use the JUnit4TestAdapter in your test classes :
  /**

* @return instance of this as Junit test case
  */
  public static junit.framework.Test suite() { return new JUnit4TestAdapter(MyTestClass.class); }

* run maven with a jdk >= 5

Try to check this: JUnit + Maven + Eclipse: Why @BeforeClass does not work?
