net.createServer still uses real file system

[TheDirigible]

When using net.createServer to create a unix domain socket (socket file), it is created in the real file system, even though mock-fs was used. Is there any fix for this?

mock-fs is not an implementation of file system, it only works in nodejs context by monkey patching some methods. Socket file is probably out of reach.

For your use case, you can try to use a real file system like tmpfs to create a transient file system in ram.

Yes, besides normal file and directory, mock-fs only has symlink.
