java - How do you test Wicket TextFields for read-only?

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

这应该可以通过以下方式解决：

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

或非常相似的东西。我现在无法测试这个，所以我不能更具体。有关更多详细信息，请查看TagTester的 JavaDocs

Answer 2

不幸的是，WicketTester这并不容易直接做到这一点，但是......

由于AttributeModifier是一种行为，您可以调用

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

并从列表中拉出AttributeModifier实例（使用instanceof 或isAssignableFrom检查）。然后经过一些反思以使事情可以访问，您可以检查是否有一个符合您预期的AttributeModifier.
