Update phpunit/phpunit requirement from ^8.5 to ^9.5

[dependabot]

Updates the requirements on phpunit/phpunit to permit the latest version.

Changelog

Sourced from phpunit/phpunit's changelog.

[9.5.10] - 2021-09-25

Changed

• PHPUnit no longer converts PHP deprecations to exceptions by default (configure convertDeprecationsToExceptions="true" to enable this)
• The PHPUnit XML configuration file generator now configures convertDeprecationsToExceptions="true"

Fixed

• #4772: TestDox HTML report not displayed correctly when browser has custom colour settings

[9.5.9] - 2021-08-31

Fixed

• #4750: Automatic return value generation leads to invalid (and superfluous) test double code generation when a stubbed method returns *|false
• #4751: Configuration validation fails when using brackets in glob pattern

[9.5.8] - 2021-07-31

Fixed

• #4740: phpunit.phar does not work with PHP 8.1

[9.5.7] - 2021-07-19

Fixed

• #4720: PHPUnit does not verify its own PHP extension requirements
• #4735: Automated return value generation does not work for stubbed methods that return *|false

[9.5.6] - 2021-06-23

Changed

• PHPUnit now errors out on startup when PHP_VERSION contains a value that is not compatible with version_compare(), for instance X.Y.Z-(to be removed in future macOS)

[9.5.5] - 2021-06-05

Changed

• The test result cache (the storage for which is implemented in PHPUnit\Runner\DefaultTestResultCache) no longer uses PHP's serialize() and unserialize() functions for persistence. It now uses a versioned JSON format instead that is independent of PHP implementation details (see #3581 and #4662 for examples why this is a problem). When PHPUnit tries to load the test result cache from a file that does not exist, or from a file that does not contain data in JSON format, or from a file that contains data in a JSON format version other than the one used by the currently running PHPUnit version, then this is considered to be a "cache miss". An empty DefaultTestResultCache object is created in this case. This should also prevent PHPUnit from crashing when trying to load a test result cache file created by a different version of PHPUnit (see #4580 for example).

Fixed

• #4632: TestDox result printer does not handle repeated test execution correctly
• #4678: Stubbed methods with iterable return types should return empty array by default
• #4692: Annotations in single-line doc-comments are not handled correctly
• #4694: TestCase::getMockFromWsdl() does not work with PHP 8.1-dev
