I've created a conf file for a connection to an address and port for stunnel whose location is in /usr/local/etc/stunnel/ and started the stunnel service.
I've binded the address to my local ip address 127.0.0.1:60005
To test the connection, I've tried to connect the address via telnet with:
telnet 127.0.0.1 60005
Turns:
Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. Connection closed by foreign host.
I know that connection is not closed by foreign host as I tried telnet with the original ip address, there is no problem.
So, how can I test my stunnel connection except using telnet? Thanks.

One way to test it is to use tcpdump.
Try: tcpdump port 60005 -n -vvvv
Then send some data to that interface: echo "blah" > nc localhost 60005
You should see packets from tcpdump; if you do not see any packets try having tcpdump listen on a different interface with the -i switch.
