Javascript Judge in Dodona -> internal error

[RobbeW]

Hi all,

When using Dodona to build a set of exercises on Javascript, I can' seem to get the judge to respond correctly. I have tried adding a reference to an testsuite.json as described in the TESTed documentation, but that seems to trigger the same internal error.

The internal error in question:

Judge exited with status code 1.
Standard Error:
node:internal/fs/utils:344
    throw err;
    ^

Error: ENOENT: no such file or directory, open '/mnt/z9UXMFN1LDKj7fmsN7rN7w/resources/tests.js'

}

Suggestion on what I appear to be doing incorrectly?

Thanks in advance!

I think there is some confusion about the TESTed judge vs. the JavaScript judge. The JavaScript judge is a judge created for just JavaScript, and expects a tests.js file in the evaluation directory. The TESTed judge is a new judge supporting multiple programming languages. This is the one expecting the testsuite.json file in the evaluation directory.

Thanks for the reply.
If the preliminary goal here is just 'getting syntax feedback' or 'no internal error' to the students (no full check on their input code); what would Dodona require?

(I only have some experience using the Python / Pythia judge to give simple syntax feedback by not adding a specified path or testplan; but Javascript does not seem to trigger the same behaviour)

This is unfortunately not possible in the JavaScript judge. It might be possible with TESTed, unfortunately I can't check that as easily (and I'm supervising an exam right now). Maybe @niknetniko knows by heart whether this is possible with TESTed?

I've looked into it; TESTed supports this (at least for JavaScript). An example is https://github.com/niknetniko/example-exercises/tree/master/syntax-check.

You need to have an empty object in testsuite.json:

{}

It is also important to set the following option in the config.json file:

{
  "options": {
    "allow_fallback": false
  }
}

@niknetniko this seems to do the trick.
I owe you a fancy coffee! Thanks for the swift reply / help!
