how to mock DBs

• dockertest

  48 3,960 4.5 Go

  Write better integration tests! Dockertest helps you boot up ephermal docker images for your Go tests with minimal work.

  

This one looks cool!, I'll need to take a look to the documentation just to see if it satisfies our needs. I have been using an alternative library that seems to be more stable: https://github.com/ory/dockertest. I like it a lot and it has some good and complete documentation with examples included. Do you have any previous experience with this one or any other benchmark against testcontainers?

• gomock

  40 9,010 2.5 Go

  Discontinued GoMock is a mocking framework for the Go programming language. (by golang)

  

In all other layers, my repositories are mocked using https://github.com/golang/mock

• InfluxDB

• Testify

  64 21,981 8.6 Go

  A toolkit with common assertions and mocks that plays nicely with the standard library

  

I usually use the testify (https://github.com/stretchr/testify) It can help you to mock your external components. For unit tests I see one way and it is not to allow external interaction (DBs, APIs, etc) while tests are going. Keep your project structure like the clean architecture (https://betterprogramming.pub/the-clean-architecture-beginners-guide-e4b7058c1165) and then, as a result, you will have opportunity to replace components and configure their behavior.

• go

  2,066 119,397 10.0 Go

  The Go programming language

  

Another approach if you want to stay at the DB level is to implement the Io/fs interface (https://pkg.go.dev/io/fs). It is currently only read-only but you can extend it with a write mode in your project (see https://github.com/golang/go/issues/45757).

• postgres

  29 2,078 7.8 Shell

  Docker Official Image packaging for Postgres (by docker-library)

  

The docker file I used is basically this one except as I mention I hack out the VOLUME line, which makes it transient.

• testcontainers-node

  26 1,646 8.4 TypeScript

  Testcontainers is a NodeJS library that supports tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.

  

I have used only testcontainers. I used it for the first time while working with Java, and then with NodeJS. When I came to know that a Golang version is available, I ended up using it since I'm now familiar with the framework irrespective of the language.

• redismock

  1 249 3.5 Go

  Redis client Mock

  

I used also other lib to mock different components like redis cache.

• WorkOS

• moq

Just replaced mockery generated mocks with https://github.com/matryer/moq Alot cleaner imo at least for me
