About

This module now uses ESM modules from v2.0.0, if you need to use CommonJS refer to v1.x.x

This simple package aim to parse lcov.info files and provide the total coverage Number without fancy formatting or anything else, either in stdout or programmatically.

Here's why:

• You need to assest coverage in your CI and fail below certain threshold
• you don't want to do unredable awk chains
• every other options outputs fancy colored output which is tediuous to parse and error prone

Installation

You can install locally

npm install lcov-total

You can install glocally

npm install -g lcov-total

Or use NPX

npx lcov-total

Usage

You can use lcov-total from command line providing lcov.info file location eg:

npx lcov-total lcov.info
# 100.00

If you pass the --gte=value flag you will get an exitCode 0 or 1 based on resulting coverage >= value expression, eg:

npx lcov-total lcov.info --gte=90
echo $?
# 0

Or programmatically

import lcovTotal from "lcov-total";
lcovTotal("/path/to/lcov.info"); // this throws if any error
