GWT Test Execution Error

Problem:

When try to execute a test class that inherits from GWTTestCase the following message error is displayed:

com.google.gwt.junit.JUnitFatalLaunchException: The test class 'stories.SomeStoryTest' was not found in module'com.appspot.projectname.ProjectName; no compilation unit for that type was seen

Reason:

The test class SomeStoryTest should be in the same package of the GWT Module, or in a subpackage.

Solution:

Change de package of the test class. In this example, change from  story.SomeStoryTest to com.appspot.projectname.client.SomeStoryTest or to some subpackage as in com.appspot.projectname.client.stories.SomeStoryTest.
