============================================================================
result :

0: Connection(name=test, isConnection=true)
1: Connection(name=turtle, isConnection=false)

itr : Connection(name=test, isConnection=true)
itr : Connection(name=turtle, isConnection=false)
before : 2
Connection(name=test, isConnection=true)
Connection(name=turtle, isConnection=false)
after : 0
