Running “pure” JUnit 4 tests using ant

Question

We have migrated to both JUnit 4 and ant 1.7

The tests runs fine in eclipse, but the annotations are ignored when running the tests using ant.

According to t

Answer 1

This happened to me and it was because I was both using annotations and extending TestCase.

public class TestXXX extends TestCase {

    @Test
    public void testSimpleValidCase() {
        // this was running
    }

    @Test
    public void simpleValidCase() {
        // this wasn't running
    }
}

When you extend TestCase you are assuming JUnit3 style so JUnit4 annotations are ignored.

The solution is to stop extending TestCase.

Answer 2

What I ended up doing was adding an Ant to one of my definitions that is used by the task>. Et voila.

Answer 3

I also tried to do tests with JUnit 4.0 without JUnit4TestAdapter, i.e. without method
public static junit.framework.Test suite() { return new JUnit4TestAdapter(SomeTestClass.class); }

I use ant 1.9.4. Running ant test verbose (ant -v ) shows

[junit] Running multiple tests in the same VM
[junit] Implicitly adding /usr/share/java/junit.jar:/usr/sharejava/ant-launcher.jar:/usr/share/java/ant.jar:/usr/share/java/ant/ant-junit.jar to CLASSPATH

Aha, but still there is some ant-junit-task. Downloading this shows in addition /usr/share/java/ant/ant-junit4.jar which is not added implicitly. I just added it explicitly:

<junit printsummary="yes" 
    fork="yes" 
    forkmode="once"
    maxmemory="1023m" 
    showoutput="no">
    ...
   <classpath>
     <pathelement path="...:${junitJar}:${hamcrestJar}:/usr/share/java/ant/ant-junit4.jar" />
   </classpath>
...
</junit>

and it worked. Without: no. I am aware that this solution is not beautiful at all...
