Istanbul
Istanbul simplifies JavaScript test coverage by instrumenting ES5 and ES2015+ code with line counters to track unit-test effectiveness. The nyc CLI integrates seamlessly with popular frameworks like tap, mocha, and AVA, allowing developers to effortlessly add coverage metrics. It supports ES6 through babel-plugin-Istanbul and handles subprocess instrumentation effectively.
