ENOENT, no such file or directory 'coverage/'

[Kikobeats]

I really don't know why this happens.

I use a shellscript to run the tests:

"$PWD"/node_modules/.bin/mocha \
  -b \
  --compilers coffee:coffee-script/register \
  --require coffee-coverage/register-istanbul \
  --require should \
  --reporter spec \
  --timeout 120000 \
  --slow 300 \
  "$@"

You can see all the code here

The problem is that --require coffee-coverage/register-istanbul line throw an Error related with the coverage folder:

✓ release a new version and hook pre releases plugins in order (163ms)


  16 passing (300ms)

the strange thing is that the folder doesn't exist before I run the script (good) and after the exceptions exists.

Any idea of what happens?

No. I'm doing (almost) exactly this, and I'm not seeing this issue. The error is in mkdirs, too, which is supposed to be creating folders. Is $PWD in fact, the current working directory here? Or is this part of a script that's setting $PWD and then changing the directory?

You can add some debug logging in ./node_modules/coffee-coverage/lib/helpers.js, inside exports.mkdirs(), and see if you can figure out the full path of the folder it's trying to create. Feels like some kind of relative path problem...

[Kikobeats]

You're right. Some debug logs before call mkdirs method:

if (options.writeOnExit) {
      return process.on('exit', function() {
        var dirName, ref1;
        try {
          dirName = path.dirname(options.writeOnExit);
          console.log('DEBUG ::');
          console.log(dirName);
          console.log(process.cwd());
          console.log(__dirname);
          mkdirs(dirName);
          return fs.writeFileSync(options.writeOnExit, JSON.stringify(global[options.coverageVar]));

output:

I suppose that is important that I'm running the command using a script. I have the script in test/test.sh, so when I call the script from the root of my project using npm test could be a conflict with process.cwd and/or __dirname...
