How to cover all the files in the directory recursively about learn-istanbul

[aamin3189]

Thanks @nelsonic . After a little digging I have found that we can write a gulp task to generate coverage report for all the files,

var gulp = require('gulp');
var istanbul = require('gulp-istanbul');

gulp.task('test', function () {
    return gulp.src(['./test/**/*.js'])
      // Right there
      .pipe(istanbul({includeUntested: true}))
      .on('finish', function () {
        gulp.src(['./test/**/*.js'])
          .pipe(istanbul.writeReports({
            dir: './coverage',
            reporters: [ 'lcov' ],
            reportOpts: { dir: './coverage'}
          }));
      });
  });

@aamin3189 that should do the trick if you are already using gulp for your build tasks. 👍

@aamin3189 great question! the easiest way to do this is to use an .istanbul.yml file, do you already have one?
