I would like to test my web app under high load.
What I'd need to do is. Load the page => click the button => fill the form => click the button.
I'd need to do this to simulate 5-10k page requests, which is expected to happen after we launch one service (based on previous years data as there's going to be some big pre-sale discount for only a couple of items)
What service or approach would be the most suitable to do this?
You can use services such as SoapUI or Loader.IO. Both are supposed to be free if I am not mistaken.
