Description
both wicketTester.executeAjaxEvent(..) aswell as wicketTester.newFormTester(..).submit(..)
cannot handle cases where multiple click behaviors are attached to the submitting component, i.e. a button, and the first behavior processed within BaseWicketTester.executeAjaxEvent(final Component component, final String event) is the non-submitting (i.e. not AjaxFormSubmitBehavior) behavior.
This first behavoir creates a brand new request after being processed, and thus clears the uploadedFile added beforehand via tester.getRequest().addFile(..) needed when submission of the form is processed.
In my case there is such a behavior (a loading indicator) that I had, as a workaround to this bug, first to remove in my test code in order to make my unit test work:
final BeladungPage startedPage = this.tester.startPage(this.beladungPage);
final File xmlFile = new File("src/test/resources/camunda.cfg.xml");
final FormComponent<?> formComponent = (FormComponent<?>) tester.getComponentFromLastRenderedPage(
"upload:form:sections:sections:0:section:body:file:upload");
// workaround for wicket bug in tester.executeAjaxEvent() / tester.newFormTester().submit() if dealing with multiple AJAX click behaviors
final Button submitButton = (Button) this.tester.getComponentFromLastRenderedPage("upload:form:buttons:buttons:0:button");
submitButton.remove(submitButton.getBehaviors(ClickAjaxEventBehavior.class).get(0));
tester.getRequest().addFile(formComponent.getInputName(), xmlFile, "application/xml");
tester.executeAjaxEvent("upload:form:buttons:buttons:0:button", "click");
// tester.newFormTester("upload:form", false).submit("buttons:buttons:0:button");
final IFeedbackMessageFilter msgFilter = new ExactLevelFeedbackMessageFilter(FeedbackMessage.ERROR);
final List<FeedbackMessage> feedbackMessages = this.tester.getFeedbackMessages(msgFilter);
Assert.assertEquals(
"[[FeedbackMessage message = \"Ein Fehler ist aufgetreten! Die markierten Felder wurden unzureichend ausgefüllt.<br>Bitte überprüfen Sie Ihre Angaben.\", reporter = form, level = ERROR], [FeedbackMessage message = \"content-type 'application/xml' wird nicht unterstützt\", reporter = file, level = ERROR]]",
feedbackMessages.toString());
