maven2 with Junit 4 ignores @Test annotations

[Sankar-5]

I am trying to use maven with Junit4 test cases. Eclipse runs these
tests just fine but maven doesn't recognize any of these tests.

Here is the code
import org.junit.Test;
import static org.junit.Assert.*;

public class AdditionTest {
          private int x = 1;
          private int y = 1;
         
          @Test
          public void addition() {
            int z = x + y;
            assertEquals(2, z);
          }
}

POM file
        <dependencies>
  <dependency>
  <groupId>org.junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.4</version>
  </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>2.4.3</version>
                                <configuration>
                                        <includes>
       
<include>**/*Test.java</include>
                                        </includes>
                                </configuration>
                        </plugin>
                </plugins>
        </build>


Am I doing anything wrong here? Or anything else needs to be done?

Thanks
Sankar

Are your tests in the src/test/java folder?

I seem to be having the same problem. I will try to find a solution online, but I was hoping someone might be able to shed some light on the situation.

I would try the following things:
1. make sure that your project respects the maven structure (sources in src/main/java, tests in src/test/java)
2. remove the settings for maven-surefire-plugin. I personally never needed to specify them. It worked out of the box
3. run maven with -e switch, perhaps you will get some hints on what exactly is happening.

Oh, and btw: what exactly is the outcome? Is maven throwing some error? Is it not running the tests at all, ignoring them?

I've head this problem before and if I'm not totally mistaken it's one of the followin

A) Your dependencies or transitive dependencies is picking up junit 3.8.X somehere. Run mvn dependency:tree and study the output, and possibly add some exclusions for transitive dependencies.

B) Your project language level is .1.3/1.4

I don't remember exactly which one it was, but I'm fairly certain it was one of them

I am happy to inform that I was able to make the test classes work. It was really strange because the tests from other modules were running but these weren't (and they all shared the same dependencies).

The root of the problem was that the test classes were named something other than the standard, so instead of having MyClassTest.java, they were named MyClassTester.java (I didn't create them). Once I changed them to the former, they all ran like they were supposed to.

However, I do think this might be a bug in the maven-surefire-plugin code. When using annotations, it shouldn't matter what the class is named, surefire should be able to "introspect" all methods that are annotated with @Test.

I guess I could also try to modify the pom to find '**/*Tester.java' classes for testing, but I try to avoid explicitly setting things as much as I can.

Regards,
