Hello,
I've been doing some unit testing of EO classes with JUnit4. I've run into a
curious situation:
1. I have a test class "AddressTest" which has the following setup method:
@BeforeClass
public static void beforeAddressTest() {
cs = ContactSet.createContactSet(editingContext());
...
}
Where cs is of the appropriate type, and editingContext() returns a
lazily-initialized ERXEC from a parent class.
2. I can run AddressTest as a JUnit test as many times as I like, and all
tests pass.
3. I've added AddressTest to a test suite:
@RunWith(value=Suite.class)
@SuiteClasses(value={ActorTest.class, AddressTest.class})
public class AllContactSetModelTests {
}
4. The suite will run and all tests pass _the first time_. If I hit the JUnit
pane's "Rerun Test" button, though, it fails on subsequent runs in
AddressTest.beforeAddressTest() at the line above calling
ContactSet.createContactSet() with:
com.webobjects.foundation.NSForwardException
[java.lang.reflect.InvocationTargetException]
null:java.lang.reflect.InvocationTargetException
at
com.webobjects.foundation._NSUtilities._explainInstantiationException(_NSUtilities.java:600)

com.webobjects.foundation._NSUtilities.instantiateObjectWithConstructor(_NSUtilities.java:639)

com.webobjects.eoaccess.EOUtilities.createAndInsertInstance(EOUtilities.java:861)

net.logicsquad.pbf.model.contactset._ContactSet.createContactSet(_ContactSet.java:322)
at
net.logicsquad.pbf.tests.model.contactset.AddressTest.beforeAddressTest(AddressTest.java:23)
...
5. If I return to WO Explorer and re-run the test suite from scratch, it
passes again.
Is the problem here obvious to anyone? Is Eclipse keeping some part of JUnit
and/or the test classes/suite loaded, and that's affecting EOF? It's not a
show-stopper, because I can always re-run the tests from WO Explorer, but it
sure would be handy to be able to use the re-run button if there are some
failures that I can fix without leaving the JUnit perspective.
