TYPO3 Core

The unittest fail, because t3lib_div::getIndpEnv('TYPO3_DOCUMENT_ROOT') does not return right path.

Solution, use PATH_site instead.

Install TYPO3 inside a subdir
Run unittest "tests/t3lib/cache/backend/t3lib_cache_backend_filebackendTest.php"
See two errors

Apply path and see errors go away

This is the exact failure:
