Thank you for contribution.
Can you please add test here?

Hi @3y3, thanks for considering my PR.
Sorry for the delay, I've finally got time to add a test.
It is not ideal but I could not find a better way to check whether an error occurred here or not :

node-inspector/lib/ScriptFileStorage.js

Line 246 in 8dd50ab

if (error) console.warn('Access to ' + node + ' from ResourceTree denied. (' + error + ')');

Let me know if you have any suggesting to improve it.

Thanks!

This is not important to check errors here.
You need only check that you have expected result with correct input.

The expected result is tested.
Checking the errors that way is the only way I found to ensure that the algorithm won't follow the symbolic links until it faces an "ELOOP" error.
I can modify the implementation to have it being tested properly though
On my environment, I simply cannot use the current version of node-inspector because of this behavior, since it takes several minutes to start (or crash).
