/**
 * FIXME: This is the way I would *like* the relay tests to be done, but it does not work at
 * present as there are still isolation issues between the peers. It seems this issue is
 * particularly apparent when a relay is being used, as it is not possible to start a new
 * relay peer after the first relay is shut down. This warrants further exploration, but
 * for now this test set will be marked as ignored and each test will be done in a separate
 * class, which will ensure they are run in separate VMs and therefore no contamination
 * between runs is possible.
