This the Test Category page
This page List the posts in the posts from the "Test" category, and show the text down to the <---more---> tag (read more). The advantage to using a custom page, is to be able to use static "page" content before the dynamic content. Though the posts will change as you add more, the static content will remain the same until you manually edit it. These pages can display a list of post titles that are linked to the posts, part or all of the post contents, newest posts, or other content that is static or dynamic.
