Hi carlo L Medina.

Thanks a lot for your response. Yes, for sure it is possible to provide an article about testing in Nest.

Generally, you can use Nest’s test utilities in combination with the TestingModule and the providers to mock your dependencies. This approach is the same as in Angular.

https://docs.nestjs.com/fundamentals/custom-providers

Besides that, you can use Jests testing utilities.

It would be great if you can tell me which things you miss in the docs and which things are unclear.
