PHP 7.4 with PHPUnit 9 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
    • Runner detects the appropriate file name to be loaded with psr-4 convention.
    • If the file does not declare a class, it's written to _solution.php or _preloaded.php which is 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 9.1 so there are some breaking changes
