From: jurvis Date: Sun, 28 Aug 2022 06:07:50 +0000 (-0700) Subject: Make payment tests more realistic X-Git-Tag: v0.0.111~21^2 X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=80daf942b2be483d6470223be31df49e0056a6f9;p=rust-lightning Make payment tests more realistic Made sure that every hop has a unique receipient. When we simulate calling `channel_penalty_msat` in `TestRouter`’s find route, use actual previous node ids instead of just using the payer’s. --- diff --git a/lightning-invoice/src/payment.rs b/lightning-invoice/src/payment.rs index 8854fcbc9..e7cc43508 100644 --- a/lightning-invoice/src/payment.rs +++ b/lightning-invoice/src/payment.rs @@ -1560,7 +1560,8 @@ mod tests { assert_eq!(inflight_map.get(&(2, false)).unwrap().clone(), 64);
