Class FakeMessagesMaker

java.lang.Object
  com.google.gwt.junit.FakeMessagesMaker

All Implemented Interfaces:

java.lang.reflect.InvocationHandler

public class FakeMessagesMaker
extends java.lang.Object
implements java.lang.reflect.InvocationHandler

Helper to make a fake implementation of any Messages interface via reflection, for use in JUnit tests. (This will not work in GWTTestCase.) All calls to the returned object return the method name followed by the passed parameters as a list surrounded by [].

Note that the default message text is very consciously not made available through the fake, to help tests ensure that specific translations of localized text are not relied upon.

Sample use:

interface MyMessages extends Messages {
   @DefaultMessage("Isn''t this the fakiest?")
   @Description("A sample message to be tested.")
   String myMessage();
 }

 public void testSimple() {
  MyMessages messages = FakeMessagesMaker.create(MyMessages.class);
  assertEquals("myMessage", messages.myMessage());
 }
