locate_wordpress_develop_tests() – Locate the wordpress-develop-tests code

Description

Locate the wordpress-develop-tests code

We're trying to find the path to the wordpress-develop-tests plugin or the "tests\phpunit" directory within an extract from SVN or git. Use these methods to locate the code:

1. wordpress-develop-tests installed as a plugin.
2. `WP_DEVELOP_DIR` environment variable – used by Jetpack
3. `WP_TESTS_DIR` environment variable – used by CMB2
4. Plugin installed inside of WordPress.org developer checkout
5. Tests checked out to /tmp

If you have a normal WordPress install then the easiest way is to use the plugin approach.

C:\svn 
\wordpress-develop 
\src 
\wp-content 
\plugins 
\oik-batch - oik-wp.php 
\tests - bootstrap.php 
\$plugin 
\tests - test-*.php 

\wordpress-develop-tests 
same directory structure as \tests below 
\tests 
\phpunit 
\build 
\data 
\includes - functions.php and other required files 
\tests 

BTW: Apologies for using Windows backslashes

Usage

$string|null = locate_wordpress_develop_tests();

Parameters

Returns

string|null the directory root for the tests files
