@maybebtc the error was not inside mocknet. the error is in assuming the peers / nets returned follow the same order. See: - https://github.com/jbenet/go-ipfs/blob/master/epictest/addcat_test.go#L100 - https://gist.github.com/jbenet/a39bb9d2f16532a03bb8 if you want the results to be sorted by peer.ID before they are returned, we can totally do that, but that's probably an unsafe assumption to make in general-- if you do your initialization async, the number of networks or peers may have changed between the two calls. LMK what you prefer. (thank you golang map chaosmonkey ;)
