def merge_results(*results)
  merged = SimpleCov::RawCoverage.merge_results(*results.map(&:original_result))
  result = SimpleCov::Result.new(merged)
  # Specify the command name
  result.command_name = results.map(&:command_name).sort.join(", ")
  result
end

.merged_result ⇒ Object

Gets all SimpleCov::Results from cache, merges them and produces a new SimpleCov::Result with merged coverage data and the command_name for the result consisting of a join on all source result’s names
