NGINX strict redirect without query parameters

Question 1

I have a URL:

https://www.example.com/test.html

This URL can have query parameters like:

https://www.example.com/test.html?cat=11&rating=5

I want to redirect ONLY:

https://www.example.com/test.html

To:

https://www.example.com/test2

When I do so via:

location = /test.html {
    return 301 https://example.com/test2;
}

The URL with parameters also redirects: https://www.example.com/test.html?cat=11&rating=5

redirects to: https://example.com/test2

Is it possible to redirect URL strictly without the affecting parameters?

UPDATE: I still want https://www.example.com/test.html?cat=11&rating=5 to work as normal, but the https://www.example.com/test.html should do the redirect to /test2

UPDATE: my local docker machine server section of NGINX

server {
    listen      80;
    listen      [::]:80;
    server_name magento.test;

    set $MAGE_ROOT /var/www/php;

    set $maintenance off;

    if (-f $MAGE_ROOT/maintenance.enable){
        set $maintenance on;
    }

    include /var/www/php/nginx.conf;
}

Question 2

Query arguments are not subject to test in location or rewrite directives, they works only with the normalized URI of HTTP request. The only way to do what you want is to check $args (or $is_args) variable:

location = /test.html {
    if ($is_args = '') {
        return 301 /test2;
    }
    ... # default request processing
}

If you show your full server block, maybe I could suggest more optimized solution. For example, if you have only one location block, something like this should work:

location / {
    if ($is_args = '') {
        rewrite ^/test\.html$ /test2 permanent;
    }
    ... # default request processing
}

However there can be a caveat with this configuration. I don't know if the various browsers takes into account query string while caching redirects, and it could lead to unconditional redirect with any request to /test.html no matter of query string presence. To avoid it I suggest to use 302 temporary redirect:

return 302 /test2;

or

rewrite ^/test\.html$ /test2 redirect;

Update

You can either add this check to server context in the main configuration file:

server {
    listen      80;
    listen      [::]:80;
    server_name magento.test;

    set $MAGE_ROOT /var/www/php;

    set $maintenance off;

    if (-f $MAGE_ROOT/maintenance.enable){
        set $maintenance on;
    }

    if ($is_args = '') {
        rewrite ^/test\.html$ /test2 permanent;
    }

    include /var/www/php/nginx.conf;
}

or to location / { ... } block of magento configuration file:

location / {
    if ($is_args = '') {
        rewrite ^/test\.html$ /test2 permanent;
    }
    try_files $uri $uri/ /index.php$is_args$args;
}
