I have a curl wrapper class for which I'm writing unit tests. The wrapper class is able to detect a lost or changed connection and restart a download accordingly. It does this by tracking how much data has been downloaded at fixed intervals.
Is there any way to manipulate the internet connection within a PHPUnit test?
Write a mock object to wrap the network communication for unit testing.
In that mock class you can freely implement any kind of behaviour, like e.g. aborting the connection on a certain condition which would seem like a dropped connection to your application.
Not directly for a PHPUnit test, but maybe still related:
You can go hardcore mode: Pull your ethernet cable or turn off the wifi.
Seriously,
On Linux and Mac OS X you can try playing with ipfw
sudo ipfw pipe 1 config bw 56Kbit/s delay 200 plr 0.2sudo ipfw add 1 pipe 1 ip from any to anyAnd turn it off with sudo ipfw delete 1
There is also comcast which is a really great and handy tool for such things!
Sadly I don't know what can be used on windows.
