Re: [Wicket-user] Unit testing - updating a DropDownChoice with Ajax

[glr]

I tried with formTester.submit() and the test went OK with that.

Anyway, thanks for informing about the fix (WICKET-254), I will take it into
use.

Regards,
Richard.

Re: [Wicket-user] Unit testing - updating a DropDownChoice with Ajax

[glr]

Hi

Here is the code for the test-case. I tried to use FormTester.select(...):

public void testSelectResources() {
// Set expectations to the mock content store
final String title1 = "MyArticle-1";
List editorials = new ArrayList();
editorials.add(title1);
// Expectations for the editor display
   
expect(this.mockArticleStore.listEditorials()).andReturn(editorials);

// Expectations for listing the resources (uploaded files).
List fileNames = new ArrayList();
fileNames.add("rsc-1.bin");
fileNames.add("rsc-2.bin");
   
expect(this.mockResourceStore.getFilenames((String)anyObject())).andReturn(fileNames);

// Replay recorded expectations
replay(this.mockArticleStore);
replay(this.mockResourceStore);

this.tester.startPage(ArticleEditor.class);

// Check if the editor page is shown.
this.tester.assertRenderedPage(ArticleEditor.class);

// Test resource selection
DropDownChoice rscValuesChoice = 
(DropDownChoice)this.tester.getLastRenderedPage().get(
"articleEditorForm:rscValuesList");
List rscValues = rscValuesChoice.getChoices();
assertTrue(rscValues.size() == 0);

FormTester formTester = 
this.tester.newFormTester("articleEditorForm", false); 
formTester.select("rscTypesList", 0);   

this.tester.executeAjaxEvent("articleEditorForm:rscTypesList",
"onchange");

rscValuesChoice = 
(DropDownChoice)this.tester.getLastRenderedPage().get(
"articleEditorForm:rscValuesList");
rscValues = rscValuesChoice.getChoices();
assertTrue(rscValues.size() == 2);

verify(this.mockResourceStore);
verify(this.mockArticleStore);
}

mockResourceStore and mockArticleStore are two mock objects used to interact
with at unit-testing time.
The AJAX event fires correctly, but the component that it would update does
not have its model in the expected state. (The production code does work
correctly as integration testing can verify it.)

[Wicket-user] Unit testing - updating a DropDownChoice with Ajax

[glr]

Hi

I have 2 DropDownChoice's on a form. When making a choice in the first, the
choices in the second are updated using AjaxFormComponentUpdatingBehavior.
(Just like in the Drop Down Choice Example of the "live action" Wicket
Examples
(http://www.wicket-library.com/wicket-examples/ajax?wicket:bookmarkablePage=:wicket.examples.ajax.builtin.ChoicePage)).

Could anyone tell me what the recommended way is to unit-test the above
case? 

I tried using WicketTester with FormTester but I cannot have the model of
the first DropDownChoice updated as a response to making a selection in it.
As a result, when the OnEvent handler of the
AjaxFormComponentUpdatingBehavior fires, it looks as if there was no
selection in the first DropDownChoice.

Thanks for your answer in advance,
Richard.
