Conner Fromknecht 396a978cec lntest+wait: replace sleeps in assertAmountSent ... This commit constructs a helper closure assertAmountSent that can be reused by other functions. The closure returns an error so that it can be used with wait.NoError or the new wait.InvariantNoError. The latter is added since the predicate could otherwise pass immediately for the sphinx_replay_persistence tests, but change shortly after. It also rounds out the wait package so that we offer all combinations of predicate and no-error style waits.		2019-12-18 23:57:12 -08:00
