I was running some tests in a Drupal 11.0.10 instance (DDEV, PHP 8.3):
$ ./vendor/bin/phpunit -c web/core/phpunit.xml ./web/core/modules/system/tests/src/Functional/Routing/RouterTest.php
and I am hitting this error:

There was 1 error:
1) Drupal\Tests\system\Functional\Routing\RouterTest::testFinishResponseSubscriber
TypeError: strcasecmp(): Argument #1 ($string1) must be of type string, null given
/var/www/html/web/core/modules/system/tests/src/Functional/Routing/RouterTest.php:49
ERRORS!
Tests: 14, Assertions: 75, Errors: 1.
Screenshot:
1. Install latest Drupal 11 release, or make sure your current D11 has phpunit installed.
2. From the directory where the ./vendor directory is located, run:
./vendor/bin/phpunit -c web/core/phpunit.xml ./web/core/modules/system/tests/src/Functional/Routing/RouterTest.php
You'll see the error mentioned above
If you take a look at this snippet from RouterTest.php (lines 49-51):
if (strcasecmp($session->getResponseHeader('vary'), 'accept-encoding') !== 0) {
$this->assertSession()->responseHeaderDoesNotExist('Vary');
}
You can add a small validation to check if $session->getResponseHeader('vary') is empty or not before calling strcasecmp(), something like this:
if (strcasecmp($session->getResponseHeader('vary') ?? "", 'accept-encoding') !== 0) {
$this->assertSession()->responseHeaderDoesNotExist('Vary');
}
After that the tests passed:
But the main question is: Are the tests expecting the Vary header from FinishResponseSubscriber to have a value? I am not sure about that.

I created a MR for the workaround, needs review.
Open to any suggestions or feel free to close this if this was addressed before.
