I also modified it with the same issue:
test('Should sign in test user', function() {
expect(2);
Ember.run(function() {
visit('/');
fillIn("input[name=email]", "test@test.com");
fillIn("input[type=password]", "password");
click("button");
andThen(function() {
ok(true, "stupid test passed");
});
});
});
