Why am I getting call to undefined function after splitting module functions to two files?

Question

Now my module has two main files:

• menu_perm.module
• menu_perm.admin.inc

I added second file to .info:

files[] = menu_perm.admin.inc

I cleared the cache.

In my test class (PHPUnit) file I am bootrapping Drupal by:

drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

and I call form submit function manually inside test function, ends with below error:

Call to undefined function menu_perm_user_form_submit()

Function is in menu_perm.admin.inc.

Before this everything was ok.

What am I doing wrong here?

Answer 1

files[] only works for class/interface autoloading, it won't include arbitrary PHP files. The docs say

Drupal now supports a dynamic-loading code registry. To support it, all modules must now declare any code files containing class or interface declarations in the .info file

You can get around it by adding a line like this to the top of your .module file:

require_once DRUPAL_ROOT . '/sites/all/modules/my_module/my_module.admin.inc';

Answer 2

Use module_load_include inside your test function, e.g.
module_load_include('inc', 'my_module', 'my_module.admin');
