[erlang-questions] Common test for Large Scale Testing - how to restart slave node in right way?

Greetings, erlangers.

I'm working on integration tests for failover requirements in my distributed system.
I use Common Test for such purposes, and especially http://www.erlang.org/doc/apps/common_test/ct_master_chapter.html
The test case runs several slave nodes, and kill them time to time. As the result I check system state after such experiment. 
I'm looking for possibility to restart slave node after my test kill it. The best way for me is to configure master node as supervisor which can restart crashed nodes. Is it possible?

I have found a few variants:
1. Use ct_slave module, stop and start function from test case code. The question is where can I get test specification in this case?
2. Use event handler, or write custom code, but it still require to parse test spec manually.
Both are required to write custom test spec parser.

Please, advice.

Regards,
Boris
