Suggested change

	In previous versions, use the ``@dataProvider`` PHPdoc annotation.
	In previous versions, use the ``@dataProvider`` PHPDoc annotation.

To make DOCtor-RST happy :)

Good catch! Fixed. Thanks.

Let's ask @symfony/docs folks if they agree on using PHPUnit 10+ in 7.2 branch ... or if they prefer to wait ... or even if they prefer to use it in earlier branches. Thanks.

I think our focus should be to be consistent with the PHPunit version across the documentation.

And the main thing is then deprecation handling (e.g. https://symfony.com/doc/current/setup/upgrade_major.html#deprecations-in-phpunit). This means we should at least switch to PHPunit 11.3 and update articles like that one to use PHPunit's error handling features. If we do this, I think it's OK to keep using PHPunit 9 (with a big warning admonition) for the PhpUnitBridge documentation until we support it (probably in 7.3 or 7.4).

For me, it's either that or keep using PHPunit 9 until we have support for PHPunit 11.3+ in the PhpUnitBridge. I don't see much value in only updating this attribute.

OK, let's close this without merging and let's update PHPUnit to 11 in Symfony 7.3 or 7.4/8.0. Thanks!
