TestBase doc header refers to two incorrect class names

API page: https://api.drupal.org/api/drupal/core%21modules%21simpletest%21lib%21Dr...

Enter a descriptive title (above) relating to abstract class TestBase, then describe the problem you have found:

The TestBase docs say:

Do not extend this class directly, use either \Drupal\simpletest\WebTestBaseBase or \Drupal\simpletest\UnitTestBaseBase.

Two problems:
a) (minor) This is a comma splice. The comma should be a semicolon ; or else it should be broken up into two sentences.
b) The class names are actually WebTestBase and UnitTestBase. They do not end in BaseBase.
