Hi
I would like to test how a Xtext generator behaves with different sources, using Integration Testing of different models.
I wrote the following code, which works fine as long as I only want to test one model file (datatypes.btc).
If want to test a second model, that needs definitions of the first one, it does not work. No surprise, I already expected that... I suspect I need to use a ResourceSet, so that both files are checked together, but how?
Has anyone done it successfully?
package foo.bttg.test;
import java.io.FileInputStream;
import java.util.List;
import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.ecore.EObject;
import org.eclipse.xtext.junit.AbstractXtextTests;
import org.eclipse.xtext.resource.XtextResource;
import org.eclipse.xtext.util.CancelIndicator;
import org.eclipse.xtext.validation.CheckMode;
import org.eclipse.xtext.validation.Issue;
import foo.bttg.meta_model.btc.BTCStandaloneSetup;
public class ExpensiveChecks extends AbstractXtextTests {
@Override
protected void setUp() throws Exception {
super.setUp();
with(new BTCStandaloneSetup());
}
private List<Issue> validate(EObject model) {
XtextResource res = ((XtextResource) model.eResource());
List<Issue> list = res.getResourceServiceProvider().getResourceValidator()
.validate(res, CheckMode.ALL, new CancelIndicator.NullImpl());
return list;
}
public void testAssignability() throws Exception {
FileInputStream datatypes = new FileInputStream(
"C:\\eclipse_workspaces\\helios\\foo.bttg.model\\src\\btc\\datatypes.btc");
FileInputStream book = new FileInputStream(
"C:\\eclipse_workspaces\\helios\\foo.bttg.model\\src\\btt\\book.btt");
XtextResource btc = getResource(datatypes, URI.createURI("datatypes.btc"));
// XtextResource btt = getResource(book, URI.createURI("book.btt"));
List<Issue> list = validate(getModel(btc));
assertEquals(list.toString(), 0, list.size());
// list = validate(getModel(btt));
// assertEquals(list.toString(), 0, list.size());
}
}
Thanks.

After getting the first resource, get its resource set and load the
second in it, approx
Resource btt = btc.getResourceSet().createResource(
URI.createURI("book.btt"));
btt.load(book, null);

You are using our test framework (AbstractXtextTests.getResource())
which loads resources in an by default XtextResourceSet. A simple cast
of the ResourceSet will do.
