Why does this have to wait half a second?
Are we actually sending a request to FIS here?

This test is for getId(). As you know, getId() return fid immediately but registers fid asynchronously. Tests have to wait for half a second while we mock registration. We dont send an actual request to FIS in tests.

I would recommend to add this explanation to the comment in the code.
Also, 500ms sounds excessive, but can't hurt maybe... :)
