From 09a36cd1bfc92e47c97222696d90953e7ec88d60 Mon Sep 17 00:00:00 2001 From: MarcoFalke Date: Fri, 3 Sep 2021 17:49:04 +0200 Subject: [PATCH] Merge bitcoin/bitcoin#22860: test: Always clear reject reason in IsStandard tx test fa1b08eb1413d547b5e322f20e6907b2f827a162 test: Always clear reject reason in IsStandard tx test (MarcoFalke) Pull request description: For some tests the reject reason wasn't cleared between runs and thus subsequent tests might (theoretically) fail to verify the correct reject reason.
