coveralls-lerna

A tool that can be used to parse test coverage results, merge reports together, and POST them to coveralls.io.

The Problem

Mono-repo tools like lerna run tests in lots of directories and leave lcov.info files all over the place. It would be useful to aggregate these and see them on code-coverage sites like Coveralls. This tool collates coverate reports, rewrites the paths in them and sends them to coveralls.

Based on the most excellent @sourceallies/coveralls-merge

Installation

npm coveralls-lerna --save-dev

Usage

CLI

coveralls-lerna

Repo Token

This tool reads the Coveralls repository token from the environment variable COVERALLS_REPO_TOKEN. If this is not set it tries to guess the CI environment and job ID, if if can't do that either it will throw an error.
