Known Vulnerabilities

This module converts the output of the excellent coverify module into something similar to the lcov.info files that some tools require.

Note: it may not work for most purposes as it uses only the line coverage.

The assumption behind this module is that the only relevant metric is the line coverage. If the line coverage is 100% then the function coverage is also 100%. If the line coverage is not 100% then it doesn't matter whether the function coverage is 100% or not.

Because test coverage is like the speed of light: 99% is better than 98%, but even 99.999% is nothing compared to 100%.

Installation

Install to use in your Node project, updating the development dependencies in package.json:

npm install browserify coverify coverify-lcov --save-dev

Usage

Run coverify with browserify and filter with coverify-lcov:

./node_modules/browserify/bin/cmd.js -t coverify test.js \
| node | ./node_modules/coverify-lcov/bin/cmd.js
