Mock Web APIs with Testcontainers in Go

#golang #coding #testing #integration #api #tutorial
In this video I show you can spin up custom docker images using Testcontainers automatically in your integration tests, and I show how you can easily spin up a custom web API inside the container to integration your code.
This is a great way to make your integration tests do almost anything, you have the power of Docker at your fingertips and can mock most anything to test properly integrating with it.
Testcontainers is an open source framework for providing throwaway, lightweight instances of databases, message brokers, web browsers, or just about anything that can run in a Docker container.

The repo for the code in this tutorial is here: github.com/sigrdrifa/testcontainers-go-api
And the editor I use is Neovide (neovim), the config is here: github.com/sigrdrifa/nvim
thanks for watching!

A really clear and easy to follow explanation! Thanks :)

[@NeuroDrizz]

Pretty cool, elegant implementation.

Thank you for this approach, i wanted a way to automate container tests that i was doing manually or through shell scripts remotely. With test containers, i could fire them up against live containers (pods) via kubernetes.

Your neovim config is amazing! Looks very similar to the Lite-XL text editor. Is there a place where I can find your neovim config(dotfiles)?

Sure thing, see the pinned comment

Hi, i like the content,
I'm a bit confused about the file path for the testcontainers.ContainerRequest...
the file path is "./test/integration/test-server/Dockerfile", but the dot means the current directory but the file is inside integration folder...😕

Hey, yea its a bit confusing but it's actually because that path is relative to the build context of the ContainerRequest, which we've set to the root of the project, and so the dot resolves to the project root and therefore we need the full path to the Dockerfile (from the root). Hope that makes sense

Can you post what Nvim plugin you're using for the Terminal?
