## What it is
Blanket.js is a seamless JavaScript code coverage library that instruments source files and reports which lines are covered by tests, working in both the browser and Node.js. It integrates with test runners like QUnit and Mocha and is explicitly no longer maintained, with Istanbul recommended as an alternative.

## Use cases
- measure javascript code coverage in browser tests
- get coverage reports for mocha tests in node
- add coverage statistics to qunit test suites
- instrument source files to track covered lines
- report coverage from travis-ci builds
- use grunt to run coverage like a traditional tool

## When to choose
- you are maintaining a legacy project already using blanket
- you need a simple browser-based coverage setup with qunit

## When to avoid
- starting a new project needing active javascript coverage support
- you want modern tooling - use istanbul/nyc instead
- you need maintained support for modern javascript syntax

## Facets
- artifact type: library
- maturity: abandoned
- function: testing
- domain: testing, developer-tools
- platform: browser, cross-platform
- tags: code-coverage, javascript, qunit, mocha, instrumentation, unmaintained, nodejs
