function StandardTest::testBlacklistMode

Tests removing disallowed tags and XSS prevention.

\Drupal\Component\Utility\Xss::filter() has the ability to run in blacklist mode, in which it still applies the exact same filtering, with one exception: it no longer works with a list of allowed tags, but with a list of disallowed tags.

@dataProvider providerTestBlackListMode

Parameters

string $value: The value to filter.

string $expected: The string that is expected to be missing.

string $message: The assertion message to display upon failure.

array $disallowed_tags: (optional) The disallowed HTML tags to be passed to \Drupal\Component\Utility\Xss::filter().
