eunit has lighter weight and is mostly designed to facilitate internal
testing of the programs at hand. That is, a single unit (usually a
module). Common Test on the other hand is designed for large-scale
testing of software systems, not necessarily Erlang. It supports
distribution and parallel testing. The downside however, is that
common test is tougher to get going initailly. As a consequence,
common test is usually employed for external testing.
In the etorrent project (a bittorrent client), we use eunit for a lot
of the internal stuff to make sure it works like it is supposed to.
But we also employ common_test to spawn alternative bittorrent clients
- written by other people - and make sure we can communicate back and
forth with them.
