Testing hooks callback

Sto sviluppando unplugin usando TDDe una cosa chenon riesco completamente atestare sono ...gli hook.

Voglio dire OK,possotestareil callback degli hook,ma comeposso verificare se un hook si attivaeffettivamente (sia hookpersonalizzati che hookpredefiniti di WordPress)? Presumo che alcunepresein giro aiuteranno,ma semplicementenon riesco a capire cosami manca.

Hoinstallato la suite ditest con WP-CLI. Secondo questa risposta ,l'hook init dovrebbe attivarsi,ma ...non è così;inoltre,il codicefunziona all'interno di WordPress.

Dallamia comprensione,ilbootstrap viene caricatoper ultimo,quindi ha sensonon attivareinit,quindi la domanda che rimane è: come diavolo dovreitestare segli hook sono attivati?

Grazie!

Ilfilebootstrap ha questo aspetto:

 $_tests_dir = getenv('WP_TESTS_DIR');
if ( !$_tests_dir ) $_tests_dir = '/tmp/wordpress-tests-lib';

require_once $_tests_dir . '/includes/functions.php';

function _manually_load_plugin() {
  require dirname( __FILE__ ) . '/../includes/RegisterCustomPostType.php';
}
tests_add_filter( 'muplugins_loaded', '_manually_load_plugin' );

require $_tests_dir . '/includes/bootstrap.php';
 

ilfiletestato ha questo aspetto:

 class RegisterCustomPostType {
  function __construct()
  {
    add_action( 'init', array( $this, 'register_post_type' ) );
  }

  public function register_post_type()
  {
    register_post_type( 'foo' );
  }
}
 

Eiltest stesso:

 class CustomPostTypes extends WP_UnitTestCase {
  function test_custom_post_type_creation()
  {
    $this->assertTrue( post_type_exists( 'foo' ) );
  }
}
 

Grazie!

I'm developing a plugin using TDD and one thing that i completely fail to test are... hooks.

I mean OK, i can test hook callback, but how could I test if a hook actually trigger (both custom hooks and WordPress default hooks)? I assume that some mocking will help, but I simply can't figure out what I'm missing.

I installed the test suite with WP-CLI. According to this answer, init hook should trigger, yet... it doesn't; also, the code works inside WordPress.

From my understanding, the bootstrap is loaded last, so it kind of make sense to not trigger init, so the question that remain is: how the heck i should test if hooks are triggered?

Thanks!

The bootstrap file looks like this:

$_tests_dir = getenv('WP_TESTS_DIR');
if ( !$_tests_dir ) $_tests_dir = '/tmp/wordpress-tests-lib';

require_once $_tests_dir . '/includes/functions.php';

function _manually_load_plugin() {
  require dirname( __FILE__ ) . '/../includes/RegisterCustomPostType.php';
}
tests_add_filter( 'muplugins_loaded', '_manually_load_plugin' );

require $_tests_dir . '/includes/bootstrap.php';

tested file looks like this:

class RegisterCustomPostType {
  function __construct()
  {
    add_action( 'init', array( $this, 'register_post_type' ) );
  }

  public function register_post_type()
  {
    register_post_type( 'foo' );
  }
}

And the test itself:

class CustomPostTypes extends WP_UnitTestCase {
  function test_custom_post_type_creation()
  {
    $this->assertTrue( post_type_exists( 'foo' ) );
  }
}

Thanks!
