Changeset 53524 for trunk/tests/phpunit/tests/image/functions.php

Message:

Tests: Refactor Tests_Image_Functions::test_is_image_negative() to use a data provider.

Using a data provider has a number of advantages:

1. If the first test case fails, it won't prevent the other test cases from being tested.
2. While the assertion used in this test method does have a "failure message" (👍), the output from PHPUnit itself will already be more descriptive in case of failure when using a data provider.
3. Using named test cases in the data provider will also make the --testdox output much more descriptive and informative.

The actual cases being tested, or the test itself have not been changed.

Includes:

• Adding a @covers annotation.

Follow-up to [184/tests], [53495], [53497], [53521], [53523].

Props jrf.
See #55652.
