From 8f5d9431a36740aa12abc0acea64df48fe32d2a6 Mon Sep 17 00:00:00 2001 From: Daniel Kraft Date: Wed, 27 Feb 2019 15:37:45 +0100 Subject: Add regtests for HTTP status codes. This adds explicit tests for the returned HTTP status codes to interface_rpc.py (for error cases) and the HTTP JSON-RPC client in general for success. PR 15381 brought up discussion about the HTTP status codes in general, and the general opinion was that the current choice may not be ideal but should not be changed to preserve compatibility with existing JSON-RPC clients. Thus it makes sense to actually test the current status to ensure this desired compatibility is not broken accidentally. --- test/functional/interface_rpc.py | 19 ++++++++++++++++++- test/functional/test_framework/authproxy.py | 26 ++++++++++++++++++-------- 2 files changed, 36 insertions(+), 9 deletions(-) (limited to 'test/functional') diff --git a/test/functional/interface_rpc.py b/test/functional/interface_rpc.py index b6955d4492..49ae0fb1a9 100755 --- a/test/functional/interface_rpc.py +++ b/test/functional/interface_rpc.py @@ -1,12 +1,22 @@ #!/usr/bin/env python3 -# Copyright (c) 2018 The Bitcoin Core developers +# Copyright (c) 2018-2019 The Bitcoin Core developers # Distributed under the MIT software license, see the accompanying # file COPYING or http://www.opensource.org/licenses/mit-license.php.
