isparta

Isparta is a code coverage tool for ES6 using babel.

Its intention is to be used with karma and karma-coverage, which provides code coverage reports using istanbul.

Installation

Isparta can be installed using

$ npm install --save-dev isparta

Usage

Not all the istanbul command/options are available with isparta
Consult isparta -h for more information

Here is an example to run a coverage over mocha tests

babel-node node_modules/isparta/bin/isparta cover --report text --report html node_modules/mocha/bin/_mocha -- --reporter dot

With Karma

To use isparta, set the instrumenter for the JavaScript file type to isparta.

coverageReporter: {
  // configure the reporter to use isparta for JavaScript coverage
  // Only on { "karma-coverage": "douglasduteil/karma-coverage#next" }
  instrumenters: { isparta : require('isparta') },
  instrumenter: {
    '**/*.js': 'isparta'
  }
}

But can customize the babel options thanks to my fork


// Note that you ".babelrc" will be the default options for babel.
var babelMoreOptions = { presets: 'es2015' };

// [...]

coverageReporter: {
  // configure the reporter to use isparta for JavaScript coverage
  // Only on { "karma-coverage": "douglasduteil/karma-coverage#next" }
  instrumenters: { isparta : require('isparta') },
  instrumenter: {
    '**/*.js': 'isparta'
  },
  instrumenterOptions: {
    isparta: { babel : babelMoreOptions }
  }
}
