Neos back end testing with UAT

Hi everyone,

Currently I want to write an automation test, UAT, to operate the CRUD of Neos nodetype. I take a look to the sample code in TYPO3.Neos and try to run that existing test but it am not success to run it. Then I try to search some online document but I cannot find. It seem like walking in the dark night without the light. Could someone guide me the packages that I can use or the sample code that I can follow.
