Just figured out how to do UnitTesting with Spring 3 and Wicket.
Spring 3 introduced a check to see if a given context was a
WebApplicationContext. That means ApplicationContextMock is not suitable for
testing (giving the infamous " No WebApplicationContext found: no
ContextLoaderListener registered?" message).
I simply extended the class and added WebApplicationContext interface.
The following example shows how to get it going (I hope the code doesn't get
messed up):
public class TestHomePage extends TestCase {
private WicketTester tester;
@Override
public void setUp() {
final WebApplicationContextMock appctx = new WebApplicationContextMock();
final ServiceOfDoom mock = createMock(ServiceOfDoom.class);
expect(mock.getIt()).andReturn("whups").anyTimes();
replay(mock);
tester = new WicketTester(new WicketApplication()) {
@Override
public ServletContext newServletContext(String path) {
MockServletContext servletContext = (MockServletContext) super
.newServletContext(path);
appctx.setServletContext(servletContext);
appctx.putBean("scratchy", mock);
servletContext
.setAttribute(
WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE,
appctx);
return servletContext;
}
};
tester.getApplication().addComponentInstantiationListener(
new SpringComponentInjector(tester.getApplication(), appctx,
false));
}
public void testRenderMyPage() {
// start and render the test page
tester.startPage(HomePage.class);
// assert rendered page class
tester.assertRenderedPage(HomePage.class);
// assert rendered label component
tester
.assertLabel("message",
"whups");
}
private class WebApplicationContextMock extends ApplicationContextMock
implements WebApplicationContext {
private ServletContext servletContext;
public <T> T getBean(Class<T> requiredType) throws BeansException {
// TODO Auto-generated method stub
return null;
}
public <A extends Annotation> A findAnnotationOnBean(String beanName,
Class<A> annotationType) {
// TODO Auto-generated method stub
return null;
}
public Map<String, Object> getBeansWithAnnotation(
Class<? extends Annotation> annotationType)
throws BeansException {
// TODO Auto-generated method stub
return null;
}
public void setServletContext(ServletContext servletContext) {
this.servletContext = servletContext;
}
public ServletContext getServletContext() {
return null;
}
}
}
