您如何测试Wicket TextFields为只读？

Question

I want to test that my Wicket TextField is set to readonly . I have set up my WicketTester but that just supports assertDisabled() which is useless and fails in my case.

I already tried tester.getComponentFromLastRenderedPage(compName).getString("readonly") and tester.getComponentFromLastRenderedPage(compName).getMarkupAttributes().get("readonly") which both sounded somewhat promising to me but failed to deliver.

Answer 1

Unfortunately, WicketTester doesn't make it easy to do this very directly, but ...

Since AttributeModifier is a behavior, you can call

Component component = tester.getComponentFromLastRenderedPage("path");
List<IBehavior> behaviors = component.getBehaviors();

and pull the AttributeModifier instances from the list (using instanceof or isAssignableFrom checks). Then after some reflection to make things accessible, you can check whether there's one that matches your expected AttributeModifier .

Answer 2

This should be solvable by:

TagTester ttest = tester.getTagByWicketId(compName);
assertNotNull(ttest.getAttribute(READONLY));

or something very similar. I can't test this right now, so I can't be more specific. For more details check the JavaDocs of TagTester
