How to test AjaxFormChoiceComponentUpdatingBehavior in WicketTester

Question

In my Wicket application I used one radio button with "yes" and "no" options. If I select "No", I should display one dropdown choice. I wrote code using AjaxFormChoiceComponentUpdatingBehavior. How do I unittest this using WicketTester?

Answer 1

Solution for Wicket 1.5.x:

 AbstractAjaxBehavior behavior = (AbstractAjaxBehavior)WicketTesterHelper.
          findBehavior(getTester().getComponentFromLastRenderedPage("path:to:component"),
                        AjaxFormChoiceComponentUpdatingBehavior.class);
 getTester().executeBehavior(behavior);

Answer 2

First select the radio button that you want.

form.select("path to radio button", 0/1)

Then execute ajax behaviour:

tester.executeBehavior((AbstractAjaxBehavior)tester.getComponentFromLastRenderedPage("path to radio buttons").getBehaviors().get(0));

Answer 3

Here is my piece of code which works perfectly for me with select box but should fiat as well for radio button if you change Behaviour class. Needed steps are:

• Insert new value into form (use FormTester)
• Find behaviour
• Execute behaviour on change

Here is an example of code:

//simulate insert new value
FormTester formTester = tester.newFormTester(PANEL_ID + FORM); 
formTester.setValue("selectBox", "newValue");
//Find onchange behaviour
AjaxFormComponentUpdatingBehavior behavior = 
       (AjaxFormComponentUpdatingBehavior) WicketTesterHelper.findBehavior(
       tester.getComponentFromLastRenderedPage(PANEL_ID + FORM + ":" + "selectBox"), 
       ajaxFormComponentUpdatingBehavior.class);
//execute onchange
tester.executeBehavior(behavior);

I missed the par how to update form value in previous answers.
