I’ve written a couple of tests for a small web app, but I get an error when I try to run the page specific tests that makes use of WicketTester.
Google sends me to a mailing list for Apache Wicket, where a user experienced the same exception. He/she said the problem was that AnnotApplicationContextMock was initialized before the Wicket Application. I’ve pasted my WicketApplication class as well.
Has any of you dealt with this error before? I’ve pasted the exception and the class below.

My page specific test class:

@SpringApplicationContext({"/com/upbeat/shoutbox/spring/applicationContext.xml", "applicationContext-test.xml"})

WicketApplication:

public Class getHomePage()

return HomePage.class;

@Override
protected void init() {
super.init();
// Enable wicket ajax debug
getDebugSettings().setAjaxDebugModeEnabled(true);
addComponentInstantiationListener(getSpringComponentInjector(this));
// Mount pages
mountBookmarkablePage("/home", HomePage.class);
mountBookmarkablePage("/exceptionPage", VeryNiceExceptionPage.class);
mount(new IndexedParamUrlCodingStrategy("/view_params", ParamPage.class));
}
protected IComponentInstantiationListener getSpringComponentInjector(WebApplication app) {
return new SpringComponentInjector(app);
}
}
I was able to fix it, seems the user from the Wicket mailing list was right, I was just unable to get it right until now.
By moving the initialization of AnnotApplicationContextMock inside of the WicketApplication getSpringComponentInjector-method I was able to get the tests running.
@Before public void setUp() { tester = new WicketTester(new WicketApplication() { @Override protected IComponentInstantiationListener getSpringComponentInjector(WebApplication app) { AnnotApplicationContextMock appctx = new AnnotApplicationContextMock(); appctx.putBean("shoutItemDao", dao); appctx.putBean("shoutService", svc); return new SpringComponentInjector(app, appctx, true); } });
