hedenface/go-cover-view

Simple Go coverage report viewer

go-cover-view

This was forked from johejo/go-cover-view for a few reasons:

1. The original didn't have support for org repos
2. I think #2 is related to #1, but the event data didn't contain the PR number - or possibly this is because of just a different flow in general
3. Need support for multiple comments and the ability to view percentage (this is not implemented yet)
4. The ability to forward coverage information to a datadog metric

Install

go get github.com/hedenface/go-cover-view
go install github.com/hedenface/go-cover-view

Basic Documentation

You can read the original documentation in the original repository's README. Most of the functionality remains similar. The biggest difference is the way that the GitHub Actions Integration works. You need to pass the PR number to the comment step (currently I recommend using 8BitJonny/gh-get-current-pr@2.0.0. Also, this currently sends a custom metric to a datadog endpoint. Future plans for decoupling this exist currently.

Ultimately, the functionality that exists in the gh-get-current-pr step will be duplicated inside this project.
