This plugin provides a simple interface for testing your custom rewrite rules.
The purpose of this plugin is to be able to test your own rewrite rules, so 
you’re probably most interested in knowing how to do that, right? The plugin 
provides a filter, <code>rewrite_testing_tests</code> to add your own tests. That filter 
passes an associative array of name => tests. The tests array is an associative 
array of URI => expected match. In the outer array, the “name” is arbitrary and 
for your own reference. In the inner array, the “URI” is the path you want to 
test, and the “expected match” is what WordPress should find as a rewrite 
match.
Enough chit-chat, here’s an example:
<pre><code>function my_rewrite_tests( $tests ) {
 return array(
 'Events' => array(
 '/event/super-bowl/' => 'index.php?event=$matches[1]',
 '/event/super-bowl/page/2/' => 'index.php?event=$matches[1]&paged=$matches[2]'
 )
 );
}
add_filter( 'rewrite_testing_tests', 'my_rewrite_tests' );
</code></pre>
You can see the <code>test_cases()</code> method for a full suite of tests for the “Day 
and Name” permalink structure. It’s not necessary to leave these in (in fact, 
the above demo would wipe them out), unless you want to make sure that your 
custom rewrites aren’t affecting core rewrites. If you aren’t using “Day and 
Name” permalinks, you’ll need to adjust the tests to fit your permalink 
structure.
<h3>Todo</h3>
<ul>
<li>Add a debug bar extension which reads a transient; the transient would be 
updated whenever rewrite rules are flushed. The debug bar extension would 
show pass/fail status and link directly to the settings page.</li>
<li>Add tests for other permalink structures?</li>
<li>Add a way to run this as part of phpunit</li>
</ul>

Rewrite Rule Testing

Regex and WordPress rewrite rules are probably my two Least Favourite Things, so this plugin is essential for making sure I haven't messed anything up :)



Nice

Unit test your rewrite rules from the WordPress Admin.

In addition to controlling your custom post type permalinks this plugin adds support for using custom taxonomies in your permalink structures as well.
Not only that but you can control the full permalink so the post type slug is not required at the start of the link.
Multiple post types can use the same permalink structure.
<h4>Usage</h4>
There are 2 ways to use this plugin:
Permalink Settings
The plugin adds fields to the permalinks settings page for any public facing custom post types.
In Code
When registering a post type you can add a value to the rewrite property with the key ‘permastruct’ to define your default permalink structure.
eg:
<pre><code><?php

register_post_type( 'my_type', array(
 ...
 'rewrite' => array(
 'permastruct' => '/%custom_taxonomy_name%/%author%/%postname%/'
 ),
 ...
) );

?>
</code></pre>

WP Permastructure

Adds the ability to configure permalinks for custom post types using rewrite tags like %post_id% and %author%.
