In 2010 I set up this blog on Tumblr mostly due to the ease of publishing and not having to worry about the hosting. I also went through…
The other day a colleague asked whether or not it’s possible to have SimpleCov return a group that only contains uncommitted changes.
The answer is yes! After some digging around, we found the following way:
# in spec_helper.rb SimpleCov.start 'rails' do add_group 'Changed' do |source_file| `git ls-files --exclude-standard --others \ && git diff --name-only \ && git diff --name-only --cached`.split("\n").detect do |filename| source_file.filename.ends_with?(filename) end end end
git ls-files --exclude-standard --others for untracked files,
git diff --name-only for unstaged files and
git diff --name-only --cached for staged files.
