Review Comment:
If we wanted to be a bit more precise about the number of calls to open_doc
just for our db and only with doc_infos:
```erlang
called_times(ReqFun, DbUrl) ->
meck:reset(couch_db),
ReqFun(),
open_doc_calls(DbUrl).
open_doc_calls(DbUrl) ->
#{path := "/" ++ DbName0} = uri_string:parse(DbUrl),
DbName = list_to_binary(DbName0),
FoldFun = fun([Db, IdOrDocInfo, _Opts], Acc) ->
case {mem3:dbname(couch_db:name(Db)), IdOrDocInfo} of
{DbName, #doc_info{}} -> Acc + 1;
{_, _}-> Acc
end
end,
lists:foldl(FoldFun, 0, meck_history(couch_db, open_doc, 3)).
meck_history(Mod, Fun, Arity) ->
[A || {_, {_, F, A}, _} <- meck:history(Mod), F =:= Fun, length(A) =:=
Arity].
```
