Attribute #[WithoutErrorHandler] to disable PHPUnit's error handler for a test method #5428
Description
| Q | A |
|---|---|
| PHPUnit version | 10* |
| PHP version | 8.2 (though irrelevant) |
| Installation Method | Composer / PHAR (either) |
Summary
Code which relies on retrieving the last error message and acting on it can no longer be tested as error_get_last() will always return null.
This can also lead to additional PHP notices being reported by PHPUnit for errors which would never occur in a real-life situation.
Current behavior
Tests which are testing code which relies on error_get_last() are failing on PHPUnit 10 with notices along these lines:
There were 2 failures:
1) Jrf\PHPUnit10\Scenario\Tests\FooTest::testMethodA
Failed asserting that exception message '' contains 'Failed to open stream'.
2) Jrf\PHPUnit10\Scenario\Tests\FooTest::testMethodB
Failed asserting that null is identical to 'Triggering'.

How to reproduce
Reproduction scenario available at: jrfnl/bug-report-reproduction-scenarios@b3d9366
GH actions build for the reproduction branch demonstrating the issue: https://github.com/jrfnl/bug-report-reproduction-scenarios/actions/runs/5378708821
Expected behavior
The error_get_last() will return the correct last error message so the code under test runs without problems and can be tested like before.
