istanbul not working?

[nikmash]

I tried passing in the istanbul: true flag and it seems it's not running istanbul.

[knpwrs]

Can I see some output?

var gulp = require('gulp-param')(require('gulp'), process.argv);
var plugins = require('gulp-load-plugins')({DEBUG: true});
plugins.mocha = require('gulp-spawn-mocha');

require('./tasks/testing/test-unit')(gulp, options);

module.exports = function(gulp, options) {
    gulp.task('test-unit', function (jenkins, app) {
        app = app;
        options.plugins.env(options.testEnv);
        var reporter = {reporter: 'nyan', istanbul: true};
        if(jenkins){
            reporter = {reporter: 'mocha-tap-reporter', istanbul: true}
        }
        return gulp.src(options.paths.unitTests[app], {read: false})
            .pipe(options.plugins.print())
            .pipe(options.plugins.mocha(reporter))
            .once('end', function(){
                process.exit();
            });
    });
};

Here's how the gulpfile works. I have the gulp task in a different file from the gulpfile itself. Right now the test runner has no issue running but there is no coverage folder generated when the istanbul: true is passed in.

Output:

@knpwrs figured it out. Turns out gulp-load-plugins isn't playing nicely with gulp-spawn-mocha.

[knpwrs]

Interesting. If you can figure out a fix I'd accept a PR to get it working, otherwise I'm going to close this for now.

Just a note: seems to be at least running istanbul with gulp-load-plugins for me. It's not covering the right files but that might be a configuration issue.
