[e2e tests for mongo-sample]

[Mnigos]

Just a e2e tests using mongo
A clear and concise description of what feature you want to be shown tests for (e.g. Authentication):
I tried to create e2e tests by when i started it it's connected to db and adding this data from tests to my db. Should i use mockingoose?

An e2e test usually should be using a database, that way you are testing the entire flow, from the request coming in, to the data being saved, to the data being retrieved. Usually it's also preferable to use a different database for testing that your dev or production database to ensure you don't have any collisions or pollution of your database. I can try to add an e2e sample for mongo though

Hey guys :)

@jmcdo29 well done with the repo!
Actually, when I looked at the tests I was looking exactly for what you have described here.

Thought about adding this e2e test, from the controller to an in-memory DB, what do you think?

[jmcdo29]

@omermorad thanks for looking to continue! You can either use an in memory database, or you can add the mongo image to the docker-compose. Either way I look forward to the contribution

[omermorad]

Great, I will work on something and send you a PR

[omermorad]

Should I modify this test? Or work on a new one?

[jmcdo29]

Add a new cats.e2e-spec.ts. I'm pretty sure that's what the TypeORM sample does
