Hello everyone! I am from the Byzer open source project.
https://github.com/byzer-org/byzer-lang
We are very happy to discover the open source project testcontainers and use it in our integration tests. And as Byzer’s global integration test base! It combines with docker to improve our Pull requests test Reaching a new level, distributed testing in the previous yarn environment and ray environment has become possible from impossible!
We documented this work of integration in the BIP:
https://github.com/byzer-org/byzer-lang/wiki/BIP-1:-Support-Integration-testing-using-docker
I would like to apply to be added to the list of who-is-using-testcontainers.
