3. 8.9.x core/tests/Drupal/Tests/RandomGeneratorTrait.php \Drupal\Tests\RandomGeneratorTrait::randomString()

Generates a pseudo-random string of ASCII characters of codes 32 to 126.

Do not use this method when special characters are not possible (e.g., in machine or file names that have already been validated); instead, use \Drupal\simpletest\TestBase::randomMachineName(). If $length is greater than 3 the random string will include at least one ampersand ('&') and at least one greater than ('>') character to ensure coverage for special characters and avoid the introduction of random test failures.

Parameters

int $length: Length of random string to generate.

Return value

string Pseudo-randomly generated unique string including special characters.
