  location /test1 {
    root /var/www/test1;
    try_files $uri /index.html;

How nginx handles requests

Answer 2

In your configuration, if there are no other server blocks, everything will work anyway.
You just need to change this curvature:

location /test1 {
    root /var/www/test1;

location /test2 {
    root /var/www/test2;

to this:

location / {
    root /var/www;
