Exercise 5 console.log not returning anything. about learnyoumongo HOT 7 CLOSED

Yes, this exercise purposefully compares stdout of both your script and one executing the expected way. Closing as this is by design. (If you have a better way of doing this, I am all ears :])

Same issue:
OSX 10.11.1, Node v0.12.7, Mongo v3.2.4, Learnyoumongo v3.0.1

Exercise 6 works, which makes me think that this is a bug, but E5 does use console.log for checking answers, so this might be by design. I'll have a look in the code and report back.
Part 2:
This line might be what's doing it, I'll check on an offline copy.
EDIT: Not by itself. I don't understand Workshopper to do anything more than guess at what does what, so I don't think I can do any more here.
Part 3:
I'm trying out some alternatives to console log:

• console.warn() - no luck
• console.error() - nope
• console.dir() - nothing

Part 4:
It's not a platform-specific thing, it fails on Ubuntu 14.04.4 with Node v4.4.0, Mongo v2.4.9, and learnyoumongo v3.0.1

Part 5 (24/3/2016 NZDT):
I've tried commenting out all instances of "stdout" in insert/exercise.js. No luck. A quick check of the diff between this exercise and the one before shows nothing that would be blocking console.log.

Same issue here on OSX 10.11.1

I seem to have found something. The line:

exercise = comparestdout(exercise)

is missing from Exercise 5. It's just after the line:

exercise = execute(exercise)

in exercise 4. Once I add it, I get messages to the console....

Update: So the above does allow me to see my console.log outputs, but it breaks the verify processor. Seems this exercise implements it's own processor as follows, which breaks Stdout somehow. I still can't figure out where yet:

exercise.addProcessor(function(mode, cb) {
var orig
this.submissionStdout.pipe(sub)
var args = this.solutionArgs
sub.on('data', function(chunk) {
chunk = chunk.toString()
if (chunk)
try {
orig = JSON.parse(chunk)
delete orig._id
}
catch (err) {
exercise.emit('fail', 'Unable to parse JSON. ' +
'Did you stringify the output?')
cb(err)
}
})

if (mode === 'verify') {
sub.on('end', function() {
if (orig) {
findDoc(args, function(err, doc) {
if (err) return cb(err)
orig = sortObj(orig)
doc = sortObj(doc)
try {
compare(orig, doc)
cb(null, true)
}
catch (e) {
console.log(e)
exercise.emit('fail', e.message)
cb(null, false)
}
//sub.end()
})
} else {
cb(null, false)
}
})
}
this.submissionStdout = through2()
if (mode === 'verify')
this.solutionStdout = through2()

if (mode === 'run') {
sub.pipe(process.stdout)
process.nextTick(function() {
cb(null, true)
})
}
})

Having the same issue here, can't also get to work this problem here in my end.
