@atakama/cover-diff v1.2.3

cover-diff

Report & enforce diff coverage on diffs only.

Install:

npm install @atakama/cover-diff

Use:

Pipe in diffs, get an lcov file out.

git diff origin/master | cover-diff > diff-cover.lcov
genhtml diff-cover.lcov -o diff-cover

Note:

If you don't have genhtml, do this:

curl -O https://raw.githubusercontent.com/linux-test-project/lcov/master/bin/genhtml
chmod +x genhtml
./genhtml diff-cover.lcov -o diff-cover

That works in most bashifed environments (including Windows under git bash).

Options:

Options are located in the package.json for your project. The default lcov path is the same as the istanbul default output path.

    "diffFile" : \<stdin\>,
    "stripRoot" : [<project-home-dir>],
}
