Thanks! I was having a hard time finding good implementations for this.

Thanks for your content! It gave me a new approach to integration tests. One of the tradeoffs of putting everything inside test containers is that you cannot mock some dependencies. Maybe you want to test with your database integration but without email integration with the SMTP server. So I prefer to only use the containers for the database or for any dockerizable external dependency that you want to integrate into your testings.

Thanks for the video! I am trying to setup a bun environment, do you know if there is a problem about it? It says that undefined symbol: node_module_register...

It was a really helpful video, thanks a lot!

This is very neat approach. Not sure if it's better than starting container and running test inside, but still noteworthy 👍

[ykhatat]

why didn't you use your docker-compos to setup the container?

[markokraljevic]

what is the advantage of using testcontainers package instead of just running tests inside app container with docker-compose run?

Hi florian, can you please make similar video using Jest also covering some unit tests as well
