javascript-testing-best-practices VS testcontainers-node

😎 You want to take your JS testing skills to the next level, here is a nice repo -> javascript-testing-best-practices

Surprised nobody referred this

Yoni Golberg's JavaScript Testing best practices guide is always a good resource to consult, for both beginners and experienced developers: https://github.com/goldbergyoni/javascript-testing-best-practices

I really like how testing is done in Rails. Why did you choose the snapshots approach? I never have seen it for this purpose, they say it's bad practice even for the frontend (check testing practices for node btw), so, why?

JavaScript Testing Best Practices, by Yoni Goldberg is a GitHub repository. It gives good practices about testing.

To be able to test for multiple databases, I recommend you using Testcontainers. That's my configuration to start the container:

I don't get it either. Why not use something like https://testcontainers.com/?

Testing with added infrastructure can be quite tricky. testcontainers aims to solve this by providing an open-source framework for providing local, lightweight containers for your application that can be immediately thrown away after use. It also has a Rust SDK!

This is a good start. But DynamoDB Local is a great fit for Testcontainers which "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."

Devservices supports the automatic provisioning of unconfigured third party services in development and test mode. They can be provided by extension leveraging (usually) TestContainer library.

I hadn’t heard of Test Containers[1], but it looks really useful - thanks for the rec.
