I like how easy it was for me (as an admin)to set up my server/environment using Jenkins Pipelines! The system works very well in combination of plugins that are available from different vendors so you can use all your favorite tools without any hassle or problems at runtime :) Nothing really bad about this product but maybe more documentation would be nice when setting things properly first time? If someone wants quick setup then they should look into other products which might have better support by community before going too deep down here :).
Automated testing process has been made easier since we started implementing Jenkis pipelines!
