Those questions still need answers, if you want someone else to be able
to tell you how to configure nginx to do your non-standard thing. (If
such a thing is even possible without extra coding.)

The "standard" thing is: requests that map directly to the filesystem
that match a directory that omit a trailing slash get a http 301 response
to include the trailing slash. That is usually what is wanted.

If you want something else, you'll have to be very clear about what it
is that you want.

The machine will do exactly what you configure it to do, not what you
hope it will do.

I'm not sure why you expected a 404 if a non-slash request names an
existing directory by default. That's not the common thing to want.

You can get that by using (for example)

  try_files $uri =404;

but that probably will not do what you want if the request *does* end
in a slash.

One request is handled in one location.

Depending on what actual configuration you used, the "/test/" url might
count as a new subrequest and start a new location search, or it
might not. See the documentation for whatever directive you are using
(explicitly or implicitly.)

For example using,

  try_files $uri $uri/index.html =404;

in both /test and /test/ locations, a request for /test would send you
the contents of the file

  /usr/share/nginx/test/test/index.html

if it exists (unless other configuration says not to), while a request
for /test/ would send you the contents of the file

  /usr/share/nginx/test-slash/test/index.html

if it exists.

(Your "try_files $uri default.txt;" is unlikely to give you a useful result.)

Good luck with it,
