Issue #19279 has been updated by kevin-j-m (Kevin Murphy). I just created the PR here: https://github.com/ruby/ruby/pull/7040 ---------------------------------------- Bug #19279: Allow `Coverage.supported?` to recognize oneshot lines mode https://bugs.ruby-lang.org/issues/19279#change-100854 * Author: kevin-j-m (Kevin Murphy) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.0 (2022-12-25 revision a528908271) [x86_64-darwin22] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Currently in Ruby 3.2.0, Coverage's new `supported?` method (introduced in https://bugs.ruby-lang.org/issues/19026) does not recognize support for oneshot lines. Given that it is an available mode of coverage, I'm proposing that `Coverage.supported?` report that oneshot lines is supported. Current behavior: ``` bash ~|⇒ ruby -v ruby 3.2.0 (2022-12-25 revision a528908271) [x86_64-darwin22] ~|⇒ irb irb(main):001:0> require "coverage" => true irb(main):002:0> Coverage.supported?(:lines) => true irb(main):003:0> Coverage.supported?(:oneshot_lines) => false ``` -- https://bugs.ruby-lang.org/
