WordPress Theme unit testing is a process to make sure our developed theme is maintaining the standard of quality in WordPress themes. In WordPress, a theme is a collection of style sheets and templates that are placed inside a folder and that folder is called a WordPress theme.

General Requirement for WordPress Theme Unit Testing:

A unique prefix must be used for all function names, classes, hooks, public/global variables, action/filter hooks.
The wp_ prefix is reserved for WordPress core functionality and must not be used by a theme.
These functions should be used in preference to basename, dirname, pathinfo, etc.
Deprecated template tags or functions are not allowed.

Following function must be available in a theme

wp_head() - just before </head>

wp_footer() - just before </body>

body_class() - inside <body> or <html> tags

post_class()

wp_head() - just before </head>

wp_footer() - just before </body>

body_class() - inside <body> or <html> tags

post_class()

The wp_enqueue_style() function must be used to enqueue all stylesheets. For more information, refer to wp_enqueue_style().
The wp_enqueue_script() function must be used to enqueue JavaScript code. For more information, refer to wp_enqueue_script().
Assets loaded from the theme directory must use get_template_directory_uri() or get_stylesheet_directory_uri() to build the URL.
