test: linter errors in tmp file

[prog1dev]

After make test -j4 I get:

...
Running JS linter...

Seems like failed cleaning after test/parallel/test-require-unicode.js

If we cannot guarantee the clean test folder before linting, maybe it is worth to add a glob for temp folders to .eslintignore?

[prog1dev]

Adding

process.on('exit', function () {
  fs.unlinkSync(dirname);
  fs.unlinkSync(path.join(dirname, 'file.js'));
  fs.unlinkSync(path.join(dirname, 'package.json'));
});

or

tmpdir.refresh();

at the end of test/parallel/test-require-unicode.js does not help

Current code base uses .tmp (with the leading .) as the prefix for the tmp directory and not tmp. That directory is leftover from a run with an older code base.

rm -rf test/tmp* and try again. That should fix it. Files in .tmp* directories are ignored by the linter.

Not needed. ESLint ignore directories that start with . by default although I'm not sure it's documented. See eslint/eslint#8429.

@Trott Thanks!
rm -rf test/tmp* fixed that for me
