Description
If I as a developer want to test for certain Feedback Messages to be rendered, currently I can only test for a complete String.
This forces me to duplicate the Feedback-Message String.
If the Message changes, the Test will break.
This is not desirable.
The patch attached extends the Wicket-Tester and allows for Testing against Property-Keys and not only the complete rendered Message.
This gives me the possibililty to change the feedback message without changing the corresponding test.
Please consider applying the Patch.
Thanks.
