I'm trying to implement a link with dynamic text in Wicket, with the username as its text. My first thought was to do something like this in the markup:

<a wicket:id="somelink"><wicket:message key="some.key">bla bla</wicket:message></a>

With the properties file looking like this:

some.key=Username is: {0}

And the code:

String username = ...
add(new Link("somelink", new StringResourceModel("some.key", this, null, username)) {
    ...
});

The problem is that I have no idea how to test that the link's text is being set to the username (in the unit test that is).
I've tried:

  • Using WicketTester's assertLabel method, but it can't cast the Link to a Label
  • Using the Link's getModelObject() method returns the original message (i.e. before formatting the username into it)
  • Adding an id to the message and accessing it directly through a path, doesn't work since I get the message that this path doesn't exist (can you even give an ID to a wicket:message element ?)

Any thoughts ?

How about

WicketTester.getTagById(java.lang.String) or WicketTester.getTagByWicketId(java.lang.String)? These return a TagTester Object and TagTester.getValue() returns the value for this tag. This includes all data between the open tag and the close tag as a String. Then you can use assertEquals on the resulting String and your expectation...

TagTester link = WicketTester.getTagByWicketId("someLink");
assertNotNull(link);
String linkText = link.getValue();
asserEquals("Username is: " + username, linkText);
