A GWT test case must extend the GWT class GWTTestCase b and implement a method
with the signature public String getModuleName() to return the name of the module
being tested C . We start the test method by instantiating the model class and initializ-
ing it with input data D , the three stock symbols "S1" , "S2" , and "S3" . Next, we call
the refreshWatchList method in listing 13.14, which performs the asynchronous
RPC E .
We need to allow the test method to complete while allowing assertions to run. To
do so, we use a GWT Timer F to schedule our assertions. Our Timer 's run method
