verified Jun 17, 2026

A Babel 6.x plugin that instruments JavaScript code with Istanbul-compatible `__coverage__` variables for test coverage collection. v1.0.0 is the latest stable release. This fork of babel-plugin-__coverage__ adds istanbul-style ignore hints and alters statement counting for conditionals. It works with Karma and mocha/nyc without additional tooling. No ongoing development; exists as a legacy solution for projects stuck on Babel 6.
