Unfortunately what you know isn't quite right.

If you had used the command "ls -la" at this point, you would have
seen something like this:

total 12
drwxr-xr-x  2 sparre sparre 4096 Oct 21 17:32 .
drwxrwxrwt 12 root   root   8192 Oct 21 17:34 ..

The important part here is the "2" in the second line.  It's the "link
count" for the file ".".  As you can see, there are two links to ".".
The one is "Test" in the parent directory, and the other is ".".

Greetings,

Jacob
