QUESTION
Most examples I've seen of how to test a Prisma-injected NestJS Service (e.g. prisma-sample in testing-nestjs) are for "end to end" testing. They actually access the database, performing actual queries and then rolling back the results if necessary.
For my current needs, I want to implement lower-level "integration" testing.
As part of this, I want to remove Prisma from the equation. I want the focus to be on my service's functionality instead of the state of data within the database and Prisma's ability to return it.
One big win of this approach is that it obviates the need to craft "setup" queries and "teardown"/reset operations for specific tests. Instead, I'd like to simply manually specify what we would expect Prisma to return.
In an environment consisting of NestJS, Prisma, and Jest, how should I accomplish this?
UPDATE: The author of the testing-nestjs project pointed out in the comments that the project does have an example of database mocking. It looks nice! Others may still be interested in checking out the Gist that I've linked to as it includes some other useful functionality.

Looking at TypeORM's BaseEntity source code, a lot of the static and instance methods reference a connectionobject, just likesave(). If you instead write your createContact` like this:

Answered 2020-Apr-24 at 21:56My team faced the same error last month!
After searching for best practices, I found an easy way to do so...
I recommend you using *.repository.ts files, so you could simply move all Mongoose stuff into that file, and leave your *.service.spec.ts much simpler and decoupled. So this error will never happen again.
Have a look at this example:
product.repository.ts
The idea is to place all Mongoose operations into the repository file, like update(), delete(), find(), populate(), aggregate(), save()...
