Question

This question is specific to using PHPUnit.

PHPUnit automatically converts php errors to exceptions. Is there a way to test the return value of a method that

Answer 1

This answer is a bit late to the party, but anyhow:

You can use Netsilik/BaseTestCase (MIT License) to test directly for triggered Notices/Warnings, without ignoring them or converting them to Exceptions. Because the notices/warnings they are not converted to an Exception, the execution is not halted.

composer require netsilik/base-test-case

Testing for an E_USER_NOTICE:

bar();

        self::assertErrorTriggered(E_USER_NOTICE, 'The notice message');
    }
}

Hope this helps someone in the future.
