List of PHP Kata to Update

PHP 8.0 with PHPUnit 9.5.2 was added. The kata on this page needs to be updated manually. Any help is appreciated!

Summary of Changes

• Files are no longer concatenated, but it should work very similarly as before because solution and preloaded files are autoloaded
• The name of the test class now required to end with Test
• Solution and Preloaded file should have <?php
  • Runner prepends this if missing for backwards compatibility, but any new code should include it
• Test file should have <?php use PHPUnit\Framework\TestCase;
  • Runner prepends this if <?php is missing for backwards compatibility, but any new code should include it
• PHPUnit is updated to 9.5.2 so there are some breaking changes
  • Testing for exceptions: PHPUnit 6 removed support for testing for exceptions with PHPDoc annotations:

   /**
   * @expectedException InvalidArgumentException
   */
   public function testForException()
   {
       functionThatShouldThrow();
   }

  new code should use expectException():

  public function testForException()
  {
      $this->expectException(InvalidArgumentException::class);
      functionThatShouldThrow();
  }
