Tips for conducting unit tests on navigator.notification.alert

I am currently facing a challenge in writing a unit test for a JavaScript function where I need to fake the navigator.notification.alert method. Can anyone provide suggestions or solutions? Below is the code snippet that I have attempted:

navigator = {  
      notification = {  
          alert: function( textStatus, null, title, button ) {  
               alert("Success!);  
      }  
   }  
};

Unfortunately, this approach does not seem to work as expected. Any insights would be greatly appreciated.

Answer №1

If you want to simulate the getter (create a custom one), you can give it a shot. This method should be effective across most browsers:

navigator.__defineGetter__('notification', function () {
    return {
        alert: function () {
            document.write("Great job!");
        }
    }
});

Check out the jsFiddle link and experiment with it yourself.
