Describe the bug
Result after running drupal-check is multiple lines of
Class PHPUnit\Framework\TestCase not found.

I found a similar issue here: #143
But doing
composer require --dev --with-all-dependencies 'drupal/core-dev:^9.2.1'
Does not fix the issue.

I also encoutered this issue, but requiring drupal/core-dev fixed it in my case.
You might also need phpspec/prophecy-phpunit:^2.

This looks similar to mglaman/phpstan-drupal#215.

[mglaman]

Fixed with latest phpstan-drupal
