The BeforeMethods attribute references 'prepareView' which is the same method being annotated. This creates a recursive call that will cause an infinite loop. The attribute should either be removed or reference a different setup method.

[Copilot]

The property 'preparedView' is declared as non-readonly but is initialized with a readonly property 'view' in the constructor. This assignment doesn't provide any value since both properties reference the same instance at construction time. Consider removing line 19 or initializing 'preparedView' differently if it's meant to be modified later.

Suggested change

	$this->preparedView = $this->view;

The heredoc content has inconsistent leading whitespace. Lines 28-33 have excessive leading spaces that will be included in the file content, which may not be intended.

Suggested change

	<?php
	declare(strict_types=1);
	/** @var \Yiisoft\View\View $this */
	echo 'PHP view';
