Asserts that a text transformed to lowercase with HTML entities decoded does contains a given string.
Otherwise fails the test with a given message, similar to all the SimpleTest assert* functions.
Note that this does not remove nulls, new lines and other characters that could be used to obscure a tag or an attribute name.
string $haystack: Text to look in.
string $needle: Lowercase, plain text to look for.
string $message: (optional) Message to display if failed. Defaults to an empty string.
string $group: (optional) The group this message belongs to. Defaults to 'Other'.
protected function assertNormalized($haystack, $needle, $message = '', $group = 'Other') {
$this
->assertTrue(strpos(strtolower(String::decodeEntities($haystack)), $needle) !== FALSE, $message, $group);
}
