Igniters, I've found that the project's test framework uses 'TcpDiscoveryMulticastIpFinder' as default IP finder for tests and there are a lot of tests written by Ignite's experts that override it to 'TcpDiscoveryVmIpFinder'.
Most of our tests starting Ignite nodes in the same JVM, that allows us using shared 'TcpDiscoveryVmIpFinder'. I think that using of 'TcpDiscoveryMulticastIpFinder' may be useful only in platforms tests, BTW multi-JVM tests use the tuned 'TcpDiscoveryVmIpFinder'. I see the following main advantages of using 'TcpDiscoveryVmIpFinder': * reducing possible conflicts in the development environment, when nodes from different clusters may find each other; * speedup of nodes initial discovery, especially on Windows; * avoiding of overwriting 'getConfiguration' and copypasta only to set up static IP finder in tests; So, I'd suggest changing the default IP finder in tests to 'TcpDiscoveryVmIpFinder' as the first step and remove related boilerplate as the second step. What do you think? -- Best Regards, Vyacheslav D.
