phpunit.covers

Code example

<?php declare(strict_types = 1);

/**
 * @covers \App\NonExistentClass
 */
class MyTest extends \PHPUnit\Framework\TestCase
{
	public function testSomething(): void
	{
		// ...
	}
}

Why is it reported?

The @covers or @coversDefaultClass annotation references an invalid class, function, or method. This can happen when:

• The referenced class or function does not exist
• The annotation value is empty
• The class name is not fully qualified (missing leading backslash)
• A @coversDefaultClass is used on a method instead of a class

This rule is provided by the phpstan-phpunit extension.

How to fix it

Ensure the @covers annotation references an existing, fully qualified class or function:

 <?php declare(strict_types = 1);

 /**
- * @covers \App\NonExistentClass
+ * @covers \App\ExistingClass
  */
 class MyTest extends \PHPUnit\Framework\TestCase
 {
 	public function testSomething(): void
 	{
 		// ...
 	}
 }

If the class name is not fully qualified, add the leading backslash:

 <?php declare(strict_types = 1);

 /**
- * @covers MyClass
+ * @covers \App\MyClass
  */
 class MyTest extends \PHPUnit\Framework\TestCase
 {
 }
