Problem/Motivation

Errors occur when using the latest stable version of PHPUnit 10 (which requires PHP 8.1) on Drupal 10.0.x. They are detailed below in the code comments.

Steps to reproduce

Install by using composer require --dev : drupal/core-dev, phpunit/phpunit, phpspec/prophecy-phpunit, symfony/phpunit-bridge, behat/mink

Remaining tasks

I was able to bypass the encountered errors by modifying 2 files :

- web/core/tests/Drupal/Tests/PhpUnitCompatibilityTrait.php

      /*
       *  Warning: Class "Drupal\TestTools\PhpUnitCompatibility\PhpUnit10\TestCompatibilityTrait" not found in /var/www/html/web/core/tests/Drupal/Tests/PhpUnitCompatibilityTrait.php on line 10
       *  Fatal error: Trait "Drupal\Tests\PhpUnitCompatibilityTrait" not found in /var/www/html/web/core/tests/Drupal/Tests/UnitTestCase.php on line 27
       */
      //class_alias("Drupal\TestTools\PhpUnitCompatibility\PhpUnit" . RunnerVersion::getMajor() . "\TestCompatibilityTrait", 'Drupal\Tests\PhpUnitCompatibilityTrait');
      class_alias("Drupal\TestTools\PhpUnitCompatibility\PhpUnit9\TestCompatibilityTrait", 'Drupal\Tests\PhpUnitCompatibilityTrait');

- web/core/tests/Drupal/Tests/UnitTestCase.php

      /*
       * Fatal error: Trait "Prophecy\PhpUnit\ProphecyTrait" not found in /var/www/html/web/core/tests/Drupal/Tests/UnitTestCase.php on line 27
       */
      //use Prophecy\PhpUnit\ProphecyTrait;
       ...
      //use ProphecyTrait;

This just allows you to run unit tests without errors, but it requires work to make the versions compatible.

PHPUnit 10 has a large number of changes and is not yet supported - Symfony does not yet work with it either, so we need to wait for their PHPUnit bridge to catch up first as well.

We don't even support PHPUnit 9.6 yet - please see #3338907: Update to PHPUnit 9.6.7, closing this as a duplicate of that issue.

Thank you for your quick feedback @longwave, I downgraded PHPUnit to version 9.5.28 and it works fine.

There was just this error for some contrib modules :
...Test::setUp() must be compatible with Drupal\KernelTests\KernelTestBase::setUp(): void
To be fixed in the respective test files by adding the void return type declaration.

This comes up in google results ahead of the current issue at #3217904: [meta] Support PHPUnit 10 in Drupal 11 so cross-linking.
