Extending and overriding GwtRunner, results in GwtTestConfigurationException: Cannot find 'web.xml' file ' for GWT module

[dominic....@gmail.com]

I'm attempting to implement the following solution as described in the answer to the following stack overflow question (I'm the one who asked the original question):

http://stackoverflow.com/questions/16100925/gwt-test-utils-unit-fail-when-run-with-jacoco

When I then try and run the tests using the extended GwtRunner I get the following exception in the first test that fails:

Anyone have any suggestions on how to resolve this?

Thanks

This error is normally thrown when some of your UI classes has instance variable is of RPC service.

You need to mock the RPC service class used by your testing UI class.

e.g   in your test case  use Mockito's

 @Mock  MyRpcServiceAsync service
