[DRE-maint] Bug#661690: ruby-nokogiri: tests rely on node ordering causing random build failures

[Neil Wilson]

Package: ruby-nokogiri
Version: 1.5.0-1
Severity: normal


The nokogiri tests 'test_document_parse_method' and 'test_subclass_parse'
in test/xml/test_document.rb try to compare the string output of the
parse with the parent string output. Unfortunately this relies on node
ordering being identical for it to work.

Hash type structures have no guaranteed ordering and this causes random
build failures e.g:
https://launchpadlibrarian.net/94763657/buildlog_ubuntu-oneiric-i386.ruby-nokogiri_1.5.0-1~oneiric1~ppa1_FAILEDTOBUILD.txt.gz
