Clone this repo, and run
make test
To locally run end-to-end tests in a Docker container, and more closely match the GitHub Action environment, you can riun
make test-docker
To run locally, without Docker:
$ make build && \
node --no-deprecation ./build/hugo-linkcheck-action.js scan https://www.mysite.com
Many GitHub actions are simply an entrypoint.sh, intead of code that can be compiled. This is recommended because it's more transparant and often easy to wrap everything in a bash script. For this project, I wanted to use the great work work in the broken-link-checker module, but that project is designed to run independently today. The output is not controllable frmo the UI. The original version of this Action used it, and had some rather difficult to grok sed and grep statements to collect the output. In the end, it's much more maintainable as a few lines of javascript, instead of hard-to-read bash.
