Testing Harness Strange Behavior

Hey Guys,

I'm seeing some really strange JUnit behavior in
combination with the testing harness and Eclipse EMF. 


Someone from the JUnit list suspected that it might be
due to a static in the harness setup.

Here's the scenario:

I'm testing a method, testLoadPomResource()

When I have the method by itself it tests fine.

When I put another test in front of it like this:
public void testCreateResourceSet() {
//Stub
assertTrue(true);
}

I get an exception like this:
java.lang.ExceptionInInitializerError
at
org.eclipse.emf.ecore.xml.type.impl.AnyTypeImpl.eStaticClass(AnyTypeImpl.java:83)
at
org.eclipse.emf.ecore.impl.EObjectImpl.eClass(EObjectImpl.java:210)

....

I get the same exception when
running JUnit with Maven or Eclipse,
so I know it is localized to
JUnit/TestHarness/EMF/Java(build 1.5.0_09-b01).

I'll paste the full test case below, in case anyone
wants to look at it further.

Cheers,
- Ole

Hey Steve,

It was all in the setUp()...but I think Eclipse EMF is
a little fuzzy.

See thread:

http://www.eclipse.org/newsportal/article.php?id=21340&group=eclipse.tools.emf#21340

Still trying to figure out why JUnit has the this
effect when running EMF.

Cheers,
- Ole

you should do all junit setup in setUp() , not the ctor. JUnit creates 
all instances in advance and stores them somewhere. This is a fact you 
can abuse, but which can also hurt you.

OK - Got it.

Apparently Eclipse EMF likes
each resourceSet = createResourceSet()

method inside each test case.
