There has been some good articles on clustering and distributed systems recently. However I haven't had much luck finding articles discussing simple ways to test that your components work in a cluster. esp. in the event of a failure or restart of one of the nodes. So I have written one of my own http://www.jtoolkit.org/articles/cluster-testing.html What I would like to know is there any good articles which have similar examples of unit testing a component when part of a node in a cluster fails or is restarted. Note: a working example would be nice.
