TL;DR: PHPUnit 10.5.32 is broken, 10.5.31 works.

After a composer update one one of my projects today, I started getting this error when running my test suite: Fatal error: Uncaught Illuminate\Contracts\Container\BindingResolutionException: Target [Illuminate\Contracts\Debug\ExceptionHandler] is not instantiable.

All the tests passed just fine…no errors or warnings. At the end of the test execution output, it displayed this stacktrace:

> php artisan test --parallel --stop-on-failure --stop-on-error

After some trial-and-error, I narrowed it down to PHPUnit 10.5.32. Something in the changeset from 10.5.31 to 10.5.32 caused this error.

This also happens only when running tests in parallel (php artisan test --parallel), suggesting to me that perhaps the PHPUnit output changed in some way that ParaTest was not expecting.

My fix, at least for now, is to stick with PHPUnit 10.5.31, and hopefully an imminent upgrade to Laravel 11 and PHPUnit 11 will resolve it.
