gulp-coverage not getting along with rewire.

[nakardo]

My tests are failing when I use gulp-coverage and rewire __set__ method. Running mocha from terminal or just gulp-mocha seems to be working fine. This is the current configuration I have:

gulp.task('test', function () {
  gulp.src('./test/*', { read: false })
    .pipe(cover.instrument({
        pattern: ['index.js', 'src/**/*.js']
    }))
    .pipe(mocha())
    .pipe(cover.gather())
    .pipe(cover.format({
      reporter: 'html',
      outFile: 'coverage.html'
    }))
    .pipe(gulp.dest('.'))
    .pipe(exit());
});

And the error I'm getting (It applies for any var):

1) Providers should return 500 updating state on database error:
     ReferenceError: Provider is not defined
      at Object.eval (eval at __set__ (/Users/nakes/Projects/api-admin/src/handlers/provider.js:206:63), <anonymous>:1:1)

Any ideas?. Thanks!

Can you use the debugDirectory option and post the instrumented file where the reference error is occurring?

[nakardo]

Sure, I've uploaded a gist for the file.

[dylanb]

ok, I think I know what the solution is. About to get on a plane, hopefully will have a solution for you when I land ;-)

[nakardo]

Thanks a lot, have a nice flight! ;)

[dylanb]

ok, looks like it was even easier than I thought, can you clone this repo and test? If it works for you, then I will publish the updated module.

[nakardo]

Sorry for the delay. It's working great now. I'll leave the issue open to close it when publishing the module if you want so. Thanks!
