The company I am working for has a mobile app that is facing issues for a certain client that says the app crashes. We incorporated Crashlytics to the app and found that the crashing is caused by low-latency network. Yet, during our testing we have never had such crashes.
Now, we are thinking about adopting the performance testing of our applications and this involves low-latency tests. Would love to know the methods that are being used out there to simulate low-latency environment. Also, do we require test cases to be written for performance testing? If yes, then what is the content of such test cases.
