def explain
  Mocktail.cabinet.unsatisfying_calls.map { |unsatisfying_call|
    dry_call = unsatisfying_call.call
    other_stubbings = unsatisfying_call.other_stubbings

    UnsatisfyingCallExplanation.new(unsatisfying_call, <<~MSG)
      `nil' was returned by a mocked `#{@stringifies_method_name.stringify(dry_call)}' method
      because none of its configured stubbings were satisfied.

      The actual call:

        #{@stringifies_call.stringify(dry_call, always_parens: true)}

      The call site:

        #{unsatisfying_call.backtrace.first}

      #{@stringifies_call.stringify_multiple(other_stubbings.map(&:recording),
        nonzero_message: "Stubbings configured prior to this call but not satisfied by it",
        zero_message: "No stubbings were configured on this method")}
    MSG
  }
