public static function DrupalTestCase::randomName

7.x drupal_web_test_case.php public static DrupalTestCase::randomName($length = 8)

Generates a random string containing letters and numbers.

The string will always start with a letter. The letters may be upper or lower case. This method is better for restricted inputs that do not accept certain characters. For example, when testing input fields that require machine readable values (i.e. without spaces and non-standard characters) this method is best.

Do not use this method when testing unvalidated user input. Instead, use DrupalWebTestCase::randomString().

Parameters

$length: Length of random string to generate.

Return value

Randomly generated string.
