How to show a content without creating node for it on Drupal site? I am creating a custom node page called node--mynode.tpl.php.
The code I'm putting in is &lt;p&gt; test&lt;/p&gt;

Unfortunately nothing shows up on my Drupal site.
I have also added a node.tpl.php on the same folder as my node--mynode.tpl.php.
However I'm not sure if I have to add any code to the node.tpl.php?

Is it anything I need to add on my template.php?

Many thanks
While not at all suggested or encouraged, if you really want to create a static page in drupal, you can fake it out by creating a page--PATH.tpl.php template, but just realize that while it will show up, behind the scenes drupal will be throwing 404 / not found errors.

See Drupal 7 Template Suggestions for more information.

What I would suggest instead, though, is to look into Drupal's Menu System and create a callback for the page in question.
