Istanbul - a JavaScript code coverage tool written in JavaScript

Features

  • All-JavaScript instrumentation library that tracks statement, branch, and function coverage.
  • Module loader hooks to instrument code on the fly
  • Command line tools to run node unit tests "with coverage turned on" and no cooperation whatsoever from the test runner
  • Multiple report formats: HTML, LCOV, Cobertura, and more.
  • Ability to use as middleware when serving JavaScript files that need to be tested on the browser.
  • Can be used on the command line as well as a library
  • Based on the awesome esprima parser and the equally awesome escodegen code generator
  • Well-tested on Node.js (prev, current and next versions) and the browser (instrumentation library only)
