+============================================================================
+Important: #80606 - Testing Framework Removal / Use composer package instead
+============================================================================
+
+See :issue:`80606`
+
+Description
+===========
+
+The TYPO3 core base testing classes were moved to a separate composer package and removed
+from the TYPO3 core. If you want to continue using the testing framework classes please use
+composer and require the package typo3/testing-framework.
+
+To make sure you don't run into path issues, you can set the following environment variables:
+TYPO3_PATH_WEB = The path to your web root
+TYPO3_PATH_PACKAGES = The path to your vendor folder
+
+Find the new package on github at:
+https://github.com/TYPO3/testing-framework
+
+And on packagist:
+https://packagist.org/packages/typo3/testing-framework
