🔍 Trace Method Calls with Ruby TracePoint

TracePoint lets you hook into Ruby's interpreter events (call, return, line) to log or inspect method execution without modifying application code. Ideal for dynamically tracing complex Gems or Rails internals.

trace = TracePoint.new(:call, :return) do |tp|
  if tp.defined_class.to_s.match?(/^ActiveRecord::/)
    Rails.logger.debug "#{tp.event} #{tp.defined_class}##{tp.method_id} at #{tp.path}:#{tp.lineno}"
  end
end

# …exercise your Rails code paths
