Networking Problems
No connection No connection between parts Latency Timeout Bandwidth Slow
Close Time to packages go and return Stop responding Bandwidth size in Mb/s Slow close connection
What are we testing?
How your app responds to network errors
User perception to network problem Business rule to the problem
Technical action to the problem

How to simulate?
Hard modify a staging env Hard to automate Low level
