With nss_wrapper you can have your own hosts file, but I don't think it 
lets you force a name to fail to resolve.

However, you can completely disable external network with 
socket_wrapper:

$ LD_PRELOAD=libsocket_wrapper.so SOCKET_WRAPPER_DIR=$PWD wget http://www.example.com/
--2016-09-07 23:36:51--  http://www.example.com/
Resolving www.example.com (www.example.com)... failed: Temporary failure in name resolution.
wget: unable to resolve host address ‘www.example.com’
