Test is executed over and over

For what reason do you think that when ember-cli hits this test, it goes bananas loading it over and over in an infinite loop.

test('a user can submit the form', function(assert) {
  authenticateSession();

  visit('/blogs/new')
  .fillIn('#title')
  .fillIn('#url')
  .click('button[type=submit]');

  andThen(function() {
    assert.equal(currentURL(), '/');
  });

});
