Or, another way would be to write a simple helper method to extract the information from a working web application. You could build some code and drop it into an abstract test case. 


Consider the following to extract component's and renderers:




private void captureMetadata() {


FacesContext context = FacesContext.getCurrentInstance();


RenderKitFactory factory = (RenderKitFactory) FactoryFinder.getFactory(FactoryFinder.RENDER_KIT_FACTORY);
RenderKit defaultRenderKit = factory.getRenderKit(context, context.getViewRoot().getRenderKitId());


Iterator cti = context.getApplication().getComponentTypes();
List componentInfo = new ArrayList();
List rendererInfo = new ArrayList();
while (cti.hasNext()) {
try {
String componentType = (String) cti.next();
UIComponent component = (UIComponent) context.getApplication().createComponent(componentType);


String family = component.getFamily();


String rendererType = component.getRendererType();
Renderer renderer = defaultRenderKit.getRenderer(family, rendererType);


String[] componentRegInfo = new String[2];
componentRegInfo[0] = componentType;
componentRegInfo[1] = component.getClass().getName();
componentInfo.add(componentRegInfo);


String[] rendererRegInfo = new String[3];
rendererRegInfo[0] = family;
rendererRegInfo[1] = rendererType;
rendererRegInfo[2] = renderer.getClass().getName();
rendererInfo.add(rendererRegInfo);


} catch (Exception e) {
e.printStackTrace();
}


}


StringBuffer buff = new StringBuffer();
buff.append("protected static final Object[] COMPONENTS = {\n");
for (int i = 0; i < componentInfo.size(); i++) {
String[] componentRegInfo = (String[]) componentInfo.get(i);


buff.append(" new String[] {\"").append(componentRegInfo[0])
.append("\", \"").append(componentRegInfo[1])
.append("},\n");


}
buff.append("};\n\n\n;");


buff.append("protected static final Object[] RENDERERS = {\n");
for (int i = 0; i < rendererInfo.size(); i++) {
String[] rendererRegInfo = (String[]) rendererInfo.get(i);


buff.append(" new String[] {\"").append(rendererRegInfo[0])
.append("\", \"").append(rendererRegInfo[1])
.append("\", \"").append(rendererRegInfo[2]).append("},\n");


}
buff.append("};\n");


System.out.print(buff.toString());


}






And the following to register with the shale test case framework:








The validators, converters and listeners can be introspected in the same fashion.


for (int i = 0; i < RENDERERS.length; i++) {
Renderer renderer = null;
renderer: for (int j = 2; j < 4; j++) {
try {
Class clazz = Class.forName(RENDERERS[i][j]);
if (clazz != null) {
renderer = (Renderer) clazz.newInstance();
if (renderer != null) {
//System.out.println(RENDERERS[i][j]);
break renderer;
}
}
} catch (ClassNotFoundException e) {
} catch (InstantiationException e) {
} catch (IllegalAccessException e) {
}
}
if (renderer != null) {
  facesContext.getRenderKit().addRenderer(RENDERERS[i][0], RENDERERS[i][1],renderer);
  }
} 




for (int i = 0; i < COMPONENTS.length; i++) {
application.addComponent(((String[])COMPONENTS[i])[0], ((String[])COMPONENTS[i])[1]);
}
