There's the Cluster Test Suite (CTS) provided with Pacemaker source code. It
can exercice any Pacemaker cluster you are able to build, with predefined
scenarios.

Sadly, there's no way (yet) to extend it with new scenario without patching it
and there's still some rough edges to deal with.

If you want to experience it, look at the tests of PAF project:
https://github.com/ClusterLabs/PAF/tree/master/test

It relies on Vagrant to build a full 3 nodes pgsql/Pacemaker cluster + 1 syslog
node collecting logs from all other nodes. All in one command (make) and 3
minutes. Then, there's some documentation about how to use CTS to exercice it.
Look at the README for more instructions.
