From: Yusuke Endoh Date: 2011-06-26T14:58:04+09:00 Subject: [ruby-core:37386] [Ruby 1.9 - Feature #4796][Open] Coverage should be restartable Issue #4796 has been updated by Yusuke Endoh. Status changed from Closed to Open Assignee deleted (Yusuke Endoh) Priority changed from Normal to Low Target version changed from 1.9.3 to 1.9.x Unfortunately this patch seems to cause SEGV on os x. [#4927] I cannot fix it because I have no os x. So I can't help but revert it. Anyone who wants this feature, please fix it by yourself or please give me a Mac :-) -- Yusuke Endoh ---------------------------------------- Feature #4796: Coverage should be restartable http://redmine.ruby-lang.org/issues/4796 Author: Xavier Shay Status: Open Priority: Low Assignee: Category: lib Target version: 1.9.x I would like a way to be able to make the following test past: require "test/unit" require "coverage" require 'tmpdir' class TestCoverage < Test::Unit::TestCase def test_restarting_coverage Dir.mktmpdir {|tmp| Dir.chdir(tmp) { File.open("test.rb", "w") do |f| f.puts <<-EOS def coverage_test_method puts :ok end EOS end Coverage.start require tmp + '/test.rb' Coverage.result Coverage.start coverage_test_method assert_equal 1, Coverage.result.size } } end end The problem is that `Coverage.start` doesn't track any files loaded before it is called. This is probably desired behaviour so that stdlib files are not tracked, but it limits the usefulness of Coverage. Specifically, I am trying to collate coverage reports from workers in multiple processes. Also I want to associate coverages with specific tests (this test executed this code, etc...). This is very difficult without being able to restart. What would be involved in doing this? If you point me in the right direction I can perhaps have a go. -- http://redmine.ruby-lang.org
