Issue #10721 has been reported by Anthony Crumley. ---------------------------------------- misc #10721: Failing test because of DNS server https://bugs.ruby-lang.org/issues/10721 * Author: Anthony Crumley * Status: Open * Priority: Normal * Assignee: * Category: test * Target version: ---------------------------------------- The following test is failing: [ 5/52] TestNetHTTP#test_failure_message_includes_failed_domain_and_port = 0.32 s 1) Failure: TestNetHTTP#test_failure_message_includes_failed_domain_and_port [/vagrant/test/net/http/test_http.rb:196]: Expected "should have raised" to include "doesnotexist.bogus:80". The problem is caused by my ISP, Charter Cable, returning a search results page instead of a failed DNS lookup for http://doesnotexist.bogus. If I change my DNS server setting on my computer to use Google DNS then the test passes. The attached patch uses a MiniTest stub to produce the DNS failure which results in the expected error message regardless of how the machine's DNS server responds to http://doesnotexist.bogus. Thanks for everything you all do, Anthony ---Files-------------------------------- dns_lookup.patch (1.06 KB) -- https://bugs.ruby-lang.org/
