Description
Symfony version(s) affected: 3.4, 4.4, 5.1, 5.2
Description
See sebastianbergmann/phpunit#4297.
The Symfony testsuite makes heavy use of the at() matcher to model multiple expected calls to a test double. The PHPUnit project plans to remove that functionality with PHPUnit 10.
How to reproduce
Run the testsuite with PHPUnit 9.3.
Possible Solution
- @greg0ire has worked on a PR for Doctrine Annotations: Remove calls to TestCase::at() doctrine/annotations#345. Maybe we can apply similar changes.
- Work with the PHPUnit project on a proper replacement for that feature.
- Switch to a different mocking framework. 🙈
Additional context
When running the 3.4 testsuite with PHPUnit 9.3, about 170 deprecation warnings are logged regarding the planned removal of that functionality: https://travis-ci.org/github/symfony/symfony/jobs/716119378
