Hello, For production clusters: 1. do tests in testing environment 2. install in production 3. do tests in production(at night with sheduled downtime if needed). If You doesn't have test environment then I suggest You to do tests in production to check if everything is working as You expected. But, if there is no change in fence_xxx script You don't need to do fence testing.
