No tests found

[toshovski]

So I tried to run the Xpect tests with tycho. As basis I used the pom file from org.eclipse.xtext.example.domainmodel.xpect.tests, but there are no tests found. Here is my pom.xml file:

My Xpect Test Runner:

package  org.company.dsl.xpect.tests;
import org.junit.runner.RunWith;
import org.xpect.runner.XpectRunner;
import org.xpect.xtext.lib.tests.XtextTests;

@RunWith(XpectRunner.class)
public class MyXpectTests extends XtextTests {

}

And the simple test

/* XPECT_SETUP org.company.dsl.xpect.tests.MyXpectTests END_SETUP */
polymorph sss {
    // XPECT errors --> "Couldn't resolve reference to Structure 'Kunde'." at "Kunde"
    structures {Kunde}
    // XPECT errors --> "Couldn't resolve reference to Element 'abc'."
    fields {abc}
}

When I call xpect in maven with -X, i get the following error message:

The name of your Java test class is probably not matched by surefire's inclusion filter. see: http://maven.apache.org/surefire/maven-surefire-plugin/examples/inclusion-exclusion.html

It should work if you rename MyXpectTests to MyXpectTest (remove the trailing "s"). Or, alternatively, configure the element for your two surefire Maven plugins.

[toshovski]

You are right! That was the problem. The example on the Xpect webpage has the same name. Maybe you should change it.

Thanks for the quick answer.

[meysholdt]

true, I should change it.
