Ruby

In the following code, only the first conditional call will appear in the result hash of the branch coverage. The second one will not because it is a setter. This appears to be a forgotten case for branch coverage.

require 'tempfile' f = Tempfile.new(['ruby', '.rb']) f.write(<<-RUBY) a = nil a&.just_a_call a&.now_a_setter = something RUBY f.close require 'coverage' Coverage.start(branches: true) load f.path puts Coverage.result # => {"/tmp/ruby20181227-1959-1rb8s2n.rb" # => {:branches=>{[:"&.", 0, 2, 2, 2, 16]=>{[:then, 1, 2, 2, 2, 16]=>0, [:else, 2, 2, 2, 2, 16]=>1}}}} 

This was there in 2.5 and is still there in 2.6
