Same remark as above, this is how to implicitely call `clearTypingNotification`:

```js
describe("#_clearTypingNotification", function() {
  it("should remove the typing class", function(done) {
    var view = new app.views.ConversationView({
      call: call,
      peer: peer,
      user: user,
      textChat: textChat,
    });
    view.$el.addClass('typing');

    view.textChat.trigger("chat:type-stop")
    
    expect(view.$el.hasClass('typing')).to.be.equal(false);
  });
});
```
