Project Configuration

This plugin is configured via the project.config file present in the repo's refs/meta/config ref. This file uses git config format. By default, the coverage percentage columns in the file list are hidden to avoid visual distraction in unrelated projects, and in order to have them displayed, please add the following config:

[plugin "code-coverage"]
  enabled = true
