I am new to Serverspec testing tool.
When running test, I got the following error.
[root@ost-svr004 serverspec]# rake spec

During the Serverspec installation, I followed the instructions from http://serverspec.org/. As the prerequisite, I also installed the "Developer Tools", Ruby and RubyGem.
In fact, when running the serverspec test for localhost Exec (local), it is okay and there is no problem occurred. But when running test for remote hosts, it is failed and this problem is occurred.
Finally , I got the solution from this link.
http://www.firedaemon.com/blog/passwordless-root-ssh-public-key-authentication-on-centos-6
I created SSH RSA key on the client machine (ie. the one you are SSH'ing from) and copy it to remote host.
