Listing 15.72
Adding an empty function
function handleSubmit(event) {}
chat.messageFormController =
Object.create(chat.formController);
chat.messageFormController.handleSubmit = handleSubmit;
With the method in place we can start testing for its behavior. Listing 15.73
shows a test that expects it to publish a message event on the model.
Listing 15.73
Expecting the controller to publish a message event
TestCase("FormControllerHandleSubmitTest", {
"test should publish message": function () {
var controller = Object.create(messageController);
var model = { notify: stubFn() };
controller.setModel(model);
controller.handleSubmit();
assert(model.notify.called);
assertEquals("message", model.notify.args[0]);
assertObject(model.notify.args[1]);
}
});
Listing 15.74 adds the method call to pass the test.
Listing 15.74
Calling
publish
function handleSubmit(event) {
this.model.notify("message", {});
}
Tests are all passing. Next up, Listing 15.75 expects the published object to
include the
currentUser
as its
user
property.
Listing 15.75
Expecting
currentUser
as
user
TestCase("FormControllerHandleSubmitTest", {
setUp: function () {
this.controller = Object.create(messageController);
this.model = { notify: stubFn() };
this.controller.setModel(this.model);
},
