Testing your full software stack on a single host with cwrap. Testing network applications correctly is hard. This talk will demonstrate how to create a fully isolated network environment for client and server testing on a single host, complete with synthetic account information, hostname resolution, and privilege separation.
The cwrap project aims to help client/server software development teams to gain full functional test coverage. It makes it possible to run several instances of the full software stack on the same machine and perform functional testing of complex network configurations. Daemons run with privilege separation and required user and group accounts, irrespective of the hosting system. The cwrap project does not require virtualization and can be used to build environments on different operating systems.
