Issue #19360 has been updated by ioquatix (Samuel Williams). Status changed from Open to Closed Backport changed from 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN to 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: REQUIRED I've merged this fix. I would like this backported to 3.2 if possible, because it's blocking correct coverage computation and I don't want to wait a year to be able to use this fix. ---------------------------------------- Bug #19360: Enabling coverage with `-r` option isn't sufficient to intercept top level script. https://bugs.ruby-lang.org/issues/19360#change-101393 * Author: ioquatix (Samuel Williams) * Status: Closed * Priority: Normal * Assignee: ioquatix (Samuel Williams) * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: REQUIRED ---------------------------------------- For some reason, Ruby's coverage library doesn't work when the file is loaded from the command line. In the below example, test2.rb loads test.rb. If you run test2.rb with coverage enabled, it will report coverage for test.rb but not test2.rb. If you run test.rb directly, no coverage is reported. ``` samuel@aiko ~/P/i/autocoverage> ruby -r "./autocoverage.rb" test.rb Hello World {} samuel@aiko ~/P/i/autocoverage> ruby -r "./autocoverage.rb" test2.rb Hello World {"/home/samuel/Projects/ioquatix/autocoverage/test.rb"=>{:lines=>[1, 1, nil, nil, 1], :branches=>{}, :methods=>{[Object, :main, 1, 0, 3, 3]=>1}}} ``` The same problem affects simplecov. ``` ruby -r "./simplecov.rb" test.rb ... similar results in coverage directory ... ``` See https://github.com/ioquatix/autocoverage for a complete reproduction. -- https://bugs.ruby-lang.org/
