You could use the TagTester for that. Example:
// <span wicket:id="myLabel" class="one-class, another-class">hello world</span> TagTester tester = wicketTester.getTagByWicketId("myLabel"); assertTrue(tester.getAttributeContains("class", "one-class")); assertTrue(tester.getAttributeContains("class", "another-class")); assertFalse(tester.getAttributeContains("class", "not-this-class")); Best regards / Met vriendelijke groet, Kees van Dieren Squins IT Solutions BV Oranjestraat 30 2983 HS Ridderkerk The Netherlands Mobile: +31 (0)6 30413841 www.squins.com Chamber of commerce Rotterdam: 24435103 2013/11/21 Martin Makundi <martin.maku...@koodaripalvelut.com> > assertContains > > > 2013/11/21 Nick Pratt <nbpr...@gmail.com> > > > Is it possible to to make assertions on the rendered HTML of a Wicket > page? > > > > Im trying to make assertions on element attributes (class contents > > specifically).
