  • ¶

    A utility class, which takes a blanket coverage object and returns a representation of its lcov coverage data, which can then be outputted in various ways.

    This was heavily inspired by Steven Looman’s work on the mocha-lcov-reporter

    var fs = require('fs');
  • ¶

    Expose The LCov generator.

    exports = module.exports = LCov;
  • ¶

    Initializes a new LCov instance, given a jscoverage blanket coverage object - generally extracted from global._$jscoverage.

    function LCov(jscoverage) {
  var fnames = Object.keys(jscoverage);

  this.output = '';

  for(var i = 0, len = fnames.length; i < len; i++) {
    var fname = fnames[i],
        data = jscoverage[fname];

    this.output += exports.reportFile(fname, data);
  }
}
  • ¶

    Writes the lcov output to a file.

    LCov.prototype.toFile = function(path) {
  fs.writeFileSync(path, this.output);
};
  • ¶

    Returns the lcov output as a String.

    LCov.prototype.toString = function() {
  return this.output;
};
  • ¶

    Generates the lcov report for a file.

    exports.reportFile = function reportFile(fname, data) {
  var ret = 'SF:' + fname + '\n';

  for(var num = 1, len = data.source.length; num <= len; num++) {
    if(data[num] !== undefined) {
      ret += 'DA:' + num + ',' + data[num] + '\n';
    }
  }

  ret += 'end_of_record\n';

  return ret;
};
