function JqueryUiLibraryAssetsTest::testAssetLoadingUnchanged

Confirms jQuery UI assets load as expected.

Compares the jQuery assets that currently load against a list of the assets that loaded prior to the deprecation of all remaining core jQuery UI libraries.

While this is similar to testLibraryAssetLoadingOrder(), it is a separate test so it can be run in a test-only context, thus confirming that asset loading is truly unchanged before and after the deprecations.

@dataProvider providerTestAssetLoading

Parameters

string $library: A pipe delimited list of libraries to check.

string[] $expected_css: The jQuery UI CSS files expected to load.

string[] $expected_js: The jQuery UI JavaScript files expected to load.

    }
    // assertEmpty() is used instead of assertSame() because we can only test
    // for the presence of assets, not their loading order. The test is designed
    // to pass before and after the jQuery UI asset changes in
    // http://drupal.org/node/3113400, which, by necessity, results in loading
    // order changes.
