Every incident is logged including the SDC's response for the particular situation. Let the humans take over and avoid the accident. Then you try to recreate it in your test environment and see what would have happened if not for human intervention. If it would have resulted in an accident, fix the code to make sure it doesn't need human intervention, it to your test case and make sure all of the existing tests pass.
