A variation on Guy's answer above, involving additional builders. Say you have an Ant builder configured:

    
        org.eclipse.jdt.core.javabuilder
        
        
    
    
        org.eclipse.ui.externaltools.ExternalToolBuilder
        
            
                LaunchConfigHandle
                <project>/.externalToolBuilders/myprojectantlaunch.launch
            
        
    

If the Ant build and Eclipse build have differing output locations, Eclipse may not be able to locate the test class on the classpath. In the case of an Ant builder, also check the configured targets for clean, auto, manual and after-clean builds, to ensure that the target which builds the unit tests is called.
