# File 'lib/simplecov/combine/lines_combiner.rb', line 12



def combine(coverage_a, coverage_b)
  acc = coverage_a.size > coverage_b.size ? coverage_a : coverage_b

  acc.size.times do |index|
    acc[index] = merge_line_coverage(coverage_a[index], coverage_b[index])
  end

  acc
end


  








  

    .merge_line_coverage(first_val, second_val)  ⇒ Integer || nil  (mod_func)
  



  

    

Return depends on coverage in a specific line



Logic:



> nil + 0 = nil



> nil + nil = nil



> int + int = int


  





  
Parameters:


    
  
  • 
    first_val
    (Integer || nil)
  
    • 
  
  • 
    second_val
    (Integer || nil)
