Template tags are not methods of WP_Query object. They are functions.

On the other hand have_posts and the_post are methods of WP_Query.

So in your code you should use:

while ($test->have_posts()) : $test->the_post();

as you do, but then:

           echo  get_the_title();
           echo  get_the_content();

Also... if you want to echo these values, it would be much better to use the_title and the_content instead - there are some additional filters and actions fired up.
