Project: 
Drupal core
Introduced in branch: 
8.8.x
Introduced in version: 
8.8.0-beta1
Issue links: 
https://www.drupal.org/node/3084493
Description: 

The SimpleTest module has been deprecated in Drupal 8, and will be removed in Drupal 9.

Production sites should never have SimpleTest module installed since it is a tool for development only.

A contributed module is now available for those who wish to continue using SimpleTest during the transition from Drupal 8 to 9.

However, developers are encouraged to write tests with PHPUnit, and to use the phpunit command line test runner: https://www.drupal.org/docs/8/phpunit/running-phpunit-tests

Note that the final decision to deprecate SimpleTest still has some dependencies on the in-progress Drupal 9 issue so exact details of the deprecation may be revised (#3075490: Move simpletest module to contrib).
