IRC Server Docker Test Images
We host a series of Docker images available here (source here) with different IRC server software running. These images are setup with consistent configurations, oper credentials, and port numbers to speed-up testing.
Test Script Runner
We've written an IRC script runner available here which makes it simple to run a set of commands and actions across different IRC servers, then output a file for easy comparison between the tested servers.
Parser Tests
The set of test files available here let developers test IRC parsers and uncover areas where they do not parse (particularly complicated or edge-case) messages or incoming lines correctly.
