GWT testing error - testing

Question

So I'm trying to write my first gwt test. I got this part figured out that I need to add gwt-dev.jar to maven pom file, but now when I run my test I get this error:
testSimple(com.karq.tvkava.client.TelekanalServiceImplTest) Time elapsed: 3.809 sec <<< ERROR!
com.google.gwt.core.ext.UnableToCompleteException: (see previous log entries)

And here's my test file
public class TelekanalServiceImplTest extends GWTTestCase {
#Override
public String getModuleName() {
return "com.karq.tvkava.tvkavaJUnit";
}
public void testSimple(){
boolean isSaved = true;
assertTrue(isSaved);
}
}

Answer 1

did you include
<inherits name="com.google.gwt.junit.JUnit" />
in your *.gwt.xml file?
If this doesn't fix your error you might want to take a look at Unit Testing GWT Applications with JUnit.
