问题描述

在最新版本中，WP_UnitTestCase 已经包含了 $factory 属性。

例如：

$post = $this->factory->post->create();

在哪里可以找到有关此功能的文档？

最佳解决方案

据我所知，目前没有文件。 official source is here 。

我还写了一个单元测试 WordPress 插件，which gives some detail about this feature 的教程。

One of the advantages of using WP_UnitTestCase is its factories. These can be accessed through the factory member variable. The factory is an object with properties that are each an instance of one of the classes defined in includes/factory.php. What do they do, you ask? They make it very simple to create users, posts, terms, etc., wherever you need them in your test. So, instead of doing this:

$args = array( /* A bunch of user data you had to make up */ ); wp_insert_user( $args );

You can just do this:

$user_id = $this->factory->user->create();

But wait, it gets even better. What if you need many users (or posts, or whatever)? You can just create them in bulk like this:

$user_ids = $this->factory->user->create_many( 25 );

That will create 25 users that you can use in your test.

The factory has the following properties that you can use:

  • $post
  • $attachment
  • $comment
  • $user
  • $term
  • $category
  • $tag
  • $blog

They may all be used in the same manner as demonstrated in the above example with the $user factory. For example, you can create a post like this:

$this->factory->post->create();

You can also specify particular arguments to use for creating the object. In the above example we created a post, but it wasn’t assigned to a particular user (the post_author field will default to 0). Sometimes we may want the post assigned to a user instead. We’d do that like this:

$user_id = $this->factory->user->create();

$post_id = $this->factory->post->create( array( 'post_author' => $user_id ) );

Also, if you need more than just the ID of the object you are creating, you don’t need to do this:

$post_id = $this->factory->post->create();

$post = get_post( $post_id );

Instead, use the create_and_get() method:

// $post will be an instance of WP_Post

$post = $this->factory->post->create_and_get();

In this example, we used the post factory, but the same is true for all of the factories.

我想我会向 WordPress 文档小组提及。也许我们可以把这个东西放到插件和主题手册中。

更新 (2015 年 6 月 20 日)：您也可以 create your own custom factories！

更新 (2016 年 9 月 27 日)：在 WordPress 4.4 中，测试已更新，以提供静态 factory()方法来访问工厂，尽管 factory 属性仍通过魔术吸气剂提供。
