From: Matt Corallo Date: Sun, 15 May 2022 19:38:01 +0000 (+0000) Subject: Make tests more robust against different connection styles X-Git-Tag: v0.0.107~14^2~1 X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=c639920dcae94d0a24941ace361630bf80c3d414;p=rust-lightning Make tests more robust against different connection styles In the next commit we'll randomize the `ConnectStyle` used in each test. However, some tests are slightly too prescriptive, which we address here in a few places. --- diff --git a/lightning/src/ln/functional_tests.rs b/lightning/src/ln/functional_tests.rs index 6f5304b81..2d52d56aa 100644 --- a/lightning/src/ln/functional_tests.rs +++ b/lightning/src/ln/functional_tests.rs @@ -1280,23 +1280,41 @@ fn test_duplicate_htlc_different_direction_onchain() { check_closed_event!(nodes[0], 1, ClosureReason::CommitmentTxConfirmed);
