After a short while, the information for the files registered should
appear in the DB Snapshot of the disk.
Test Steps:
- Start server.
- Copy over a small test FITS file in 3 copies.
- Send a REGISTER Command to register the files copied over
(specifying root directory of the files).
- Check that the DB Snapshot is updated within a given period of time.

Synopsis:
File existing, remove via path, +/-execute.
Description:
The purpose of the test is to verify the normal functioning of the
DISCARD Command when DISCARD'ing files referred to by their path.
It is tried both to execute the command with execute=0 and execute=1.
The file is not registered in the NGAS DB.
This simulates the situation where spurious files are removed from the
NGAS system only referred to by their path.
Expected Result:
When the DISCARD Command is issued, execute=0, the NG/AMS Server should
find the file and return a response indicating that the file is only
available in 1 copy. When submitting the DISCARD Command with
execute=1, the file should disappear from the disk.
Test Steps:
- Start NG/AMS Server.
- Copy a test file onto a disk of the NGAS System.
- Issue a DISCARD Command specifying the copied file (execute=0).
- Check that the response indicates that the DISCARD Request is
granted.
- Reissue the DISCARD Command specifying the copied file (execute=1).
- Check that the response indicates that the file has been removed.
- Check that the file has disappeared from the disk.
