node.js - Mocking file system contents not working with gulp.src -

-

i'm trying use mock-fs mock file system contents test gulp tasks. unfortunately, gulp.src doesn't seem play mock-fs. specifically, enoent errors:

message:     enoent, lstat '/vagrant/study-node-heroku/instances/development/app.json' details:     errno: -2     code: enoent     path: /vagrant/study-node-heroku/instances/development/app.json     domainemitter: [object object]     domain: [object object]     domainthrown: false stack: error: enoent, lstat '/vagrant/study-node-heroku/instances/development/app.json'     @ error (native)

other parts of code , test code access mock-fs-created files fine.

what doing wrong? suspect problem related gulp's usage of vinyl.

here function under test:

var herokutarball = function(options, done) {   var instance = options.instance || 'development';   var tarballname = options.tarballname || instance   var tarballpath = path.join(config.temp, tarballname + '.tar.gz');   var files = path.join(config.instances, instance, '**/*');   yassert.file(path.join(config.instances, instance, 'app.json'));    async.waterfall([     function(cb) {       del([tarballpath], cb);     },     function(err, cb) {       gulp.src(files)         .pipe(tar(tarballname + '.tar'))         .pipe(gzip())         .pipe(gulp.dest(config.temp))         .pipe(gcallback(cb));     }   ], function(err, result) {     if (err) return err;     return done(err, tarballpath);   }); }

and here test snippet:

describe('gulp heroku:tarball', function() {   after('something', function() {     mock.restore();       });    before('something', function() {     mock({       'instances/development': {         'app.json': 'test content'       }     });   });    it('creates tarball', function(done) {     var options = {}      heroku.herokutarball(options, function(err, result) {       expect(result).to.be.a('string');       yassert.file(result);       done();     });   }); });

notice yassert (yeoman-assert) calls pass fine -- file there. if take function gulp.src call out of async waterfall, error goes away (and test fails of course).

issue posted @ https://github.com/tschaub/mock-fs/issues/44

you not doing wrong, mock-fs readme states:

note mock-fs not compatible graceful-fs@3.x works graceful-fs@4.x.

looking @ dependencies of gulp get:

$ npm info gulp devdependencies.graceful-fs ^3.0.0

hence, gulp still dependent on graceful-fs@3.x, therefore mock-fs not work.

ymmv, maybe vinyl-fs-mock alternative?
