Integration testing with jsdom #50

avh4 · 2014-06-07T15:05:56Z

Following this discussion #45 (comment) which led to a solution with min-document, here is a minimal repro example with jsdom. The event does not get fired.

var jsdom = require('jsdom').jsdom;
var mercury = require('mercury');
var h = mercury.h;
var event = require('synthetic-dom-events');

var callCount = 0;

var click = mercury.input();
click(function() { callCount++; });
function render(onClick) {
  return h('button', {'ev-click': mercury.event(onClick)}, 'Click Me');
};

describe('integration tests', function() {
  var document, $;

  beforeEach(function(done) {
    var doc = jsdom('<html><body></body></html>');
    var window = doc.parentWindow;
    document = window.document;
    jsdom.jQueryify(doc.parentWindow, "../node_modules/jquery/dist/jquery.js", function() {
      $ = window.$;
      done();
    });
  });

  describe('clicking the button', function() {
    beforeEach(function(done) {
      var div = document.createElement('div');
      mercury.app(div, mercury.value(click), render, {document: document});
      document.body.appendChild(div);
      $('button').click();
      // Also tried $('button').trigger('click');
      setTimeout(done);
    });

    it('increments the counter', function() {
      expect(callCount).to.equal(1);
    });    
  });
});

The text was updated successfully, but these errors were encountered:

The handler fn in dom-delegator is never getting called, so it seems like either the jquery click()/trigger() are not causing the right events for the delegator to pick up, or the delegator is not initialized correctly.

If this is the entire code, it seems that a Dom-Delegator is never being instantiated.

hg.app() creates a delegator for you.

This is mostly an issue about testing with min-document vs jsdom. We've only verified min-document.
