I've figured out that it was me didn't include JavaMemoryAdaptor Framework. I only notice this until I copy the stacktrace from Junit perspective and found out following line:

Caused by: java.lang.IllegalStateException: Unable to get the name of the class to instantiate for the adaptor framework JavaMemoryAdaptor. The possible causes for this error are: the adaptor framework is not installed on your system, the adaptor framework is not linked into your application, or the info dictionary for this adaptor is corrupted.

I should have look at it more carefully. My Bad. :)

Harvey

Hi Paul,

I've following code in setup which should do the tricks but it was never called:

public void setUp() throws Exception {
if(EOModelGroup.defaultGroup().modelNamed("MyModelForTest")==null) {
EOModelGroup.defaultGroup().addModelWithPath(PATH_TO_MYTESTMODEL);
System.out.println("MyModelForTest has been manually loaded.");
}
}


and this is the log shown in console:

[2009-12-14 17:39:50 EST] <main> Initialized : er.prototypes.ERPrototypes


and this is the exception:

Anybody has any update on this issues? I am the next lucky winner for this one. I've updated to the latest Wonder library (2009-08-20) and using the latest Juint (4.8.1) but still have this problem. Tried ERXTestCase but that doesn't work for me. My test would not run at all which is good I guess. Also, I am using ERXMemoryAdaptor in the model so I don't know if this is not supported. Any help would be much appreciated.

I'm using JUnit4 and loading models manually when I need them.  There may be a better way.  In any case, in a superclass of all my test classes is this method:

public static void setUp(String modelName) {
try {
if (EOModelGroup.defaultGroup().modelNamed(modelName) == null) {
EOModel model =
new EOModel(new File("Resources/" + modelName
+ ".eomodeld").toURI().toURL());
EOModelGroup.defaultGroup().addModel(model);
}
} catch (MalformedURLException e) {
throw new RuntimeException("Could not load EO Model.");
}
}

That's called by the following method in the subclasses:

@BeforeClass
public static void setUp() {
setUp(MODEL_NAME);
}

Where MODEL_NAME is defined in the subclass to load the appropriate model.  Loading the models manually like this seems to be sufficient to initialise Wonder.  This appears on the console when I run any of these tests:

[2009-12-14 16:12:51 CST] <main> Initialized : er.extensions.ERXExtensions
[2009-12-14 16:12:51 CST] <main> Initialized : er.prototypes.ERPrototypes
[2009-12-14 16:12:51 CST] <main> Initialized : er.ajax.Ajax
[2009-12-14 16:12:51 CST] <main> Initialized : er.directtoweb.ERDirectToWeb

[2009-12-14 16:12:51 CST] <main> Initialized : er.selenium.ERSelenium


Again, there may be a better way.  But ensuring a model was never loaded twice seemed to get rid of the InvocationTargetExceptions I was getting.
