Hi
I have a test class which inherits from AbstractXtextTests
inside this class I have two test methods which call another method
which performs these operations to load a genmodel (the variable model
is an instance of the model corresponding to the DSL)
URI uri = URI.createURI(genmodel);
ResourceSet resourceSet = model.eResource().getResourceSet();
Map<String, Object> extensionToFactoryMap = resourceSet
..getResourceFactoryRegistry().getExtensionToFactoryMap();
if (!extensionToFactoryMap.containsKey("genmodel")) {
EcoreResourceFactoryImpl ecoreFactory = new EcoreResourceFactoryImpl();
extensionToFactoryMap.put("genmodel", ecoreFactory);
GenModelPackage.eINSTANCE.eClass();
}
Resource resource = resourceSet.getResource(uri, true);
this code snippet works if I run one of the two test methods, but if I
run the entire test class as a suite, the second method fails with an
error like the following
org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1Diagnos ticWrappedException:
org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri
'http://www.eclipse.org/emf/2002/GenModel' not found.
( file:///home/bettini/work/xtext/typesystem/org.eclipse.xtext .typesystem.generator.tests/models/FJ.genmodel,
9, 58)
I can only think this is due to the way tearDown() is implemented in
AbstractXtextTests?
Note that the above two test methods produce the same error also if I
exchange their order: the second method in order always fails...
any clue please?
thanks in advance
Lorenzo

Lorenzo,
You'd be better to run as a plugin JUnit test. Failing that, the idiom
GenModelPackage.eINSTANCE.eClass() ensures that the GenModelPackage is
initialized and registered in the global registry, so in the failing
case, it seems likely that nothing is ensuring that this happens...

Thanks for your answer Ed.
what worries me is that it works when the first method is invoked, but
not when the second one is invoked (and it does not depend on the
methods themselves but on the order they are executed in the test
suite); so I was curious about that: probably the tearDown method of
the abstract test class in xtext tears down too much ;)
cheers
