composer(deps-dev): bump phpunit/phpunit from 8.5.15 to 8.5.16

[dependabot]

Bumps phpunit/phpunit from 8.5.15 to 8.5.16.

Changelog

Sourced from phpunit/phpunit's changelog.

[8.5.16] - 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

• #4663: TestCase::expectError() works on PHP 7.3, but not on PHP >= 7.4
• #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
