function simpletest_test_get_all in SimpleTest 7.2

Same name and namespace in other branches

1. 8.3 simpletest.module \simpletest_test_get_all()
2. 6.2 simpletest.module \simpletest_test_get_all()
3. 7 simpletest.module \simpletest_test_get_all()

Get a list of all of the tests provided by the system.

The list of test classes is loaded from the registry where it looks for files ending in ".test". Once loaded the test list is cached and stored in a static variable. In order to list tests provided by disabled modules hook_registry_files_alter() is used to forcefully add them to the registry.

Return value

An array of tests keyed with the groups specified in each of the tests getInfo() method and then keyed by the test class. An example of the array structure is provided below.

    $groups['Blog'] => array(
      'BlogTestCase' => array(
        'name' => 'Blog functionality',
        'description' => 'Create, view, edit, delete, ...',
        'group' => 'Blog',
      ),
    );
