How can I test the net-connectivity of app in performance?
I want to Test the net-connectivity range of the app in performance. For example, if the connection scale is 3G in some regions, the behavioral changes may happen in the connection depending on the speed of the internet.
So how can I test the behaviour of my application under such circumstances?
If you need to do some form of an ad-hoc testing it can be simulated using browser developer tools
If you want to assess your web application performance under the load you could consider using a load testing tool like Apache JMeter, it is possible to throttle JMeter to simulate slow networks like 3G by manipulating JMeter Properties in particular:
httpclient.socket.http.cps
httpclient.socket.https.cps
