Feature: mongodb as replica set (single node)

What are you trying to do?

Unit testing of Mongodb transactions.

Why should it be done this way?

mongomock can often be used in unit testing of mongodb-related functionality. It's faster and easier than using docker containers for such tests. But perhaps one of the most important scenarios in which mongomock is not applicable is testing the functionality using MongoDB transactions. At the moment, transaction mocking is not implemented in mongomock. But even if support for this was implemented there, such sensitive functionality (using transactions) would like to be checked "naturally". But as you know, transactions are possible only for replica sets, which the default MongoDB container is not. It is possible to configure mongodb as a replicaset (although with one node, but I think this is not critical for testing).

If you find this functionality useful here in the public, I can provide a PR (either as a separate Mongodb container, or extend the current MongoDbContainer with configuration options). What do you think about it?

Commencez par le MongoDbContainer actuel et la configuration par défaut du conteneur MongoDB. Vérifiez comment un replica set à nœud unique peut être configuré pour des tests basés sur des conteneurs, puis vérifiez que les transactions MongoDB peuvent s’exécuter via le conteneur ainsi obtenu. Le travail est terminé lorsque les utilisateurs peuvent utiliser le conteneur pour tester les fonctionnalités de transaction sans configurer de replica set externe.
