Kitchen verify on `bash` Inspec results in a undefined method

Hi,
I was using bash Inspec resource to verify a command usage,but when I try kitchen verify, it complains of the bash resource as undefined.I observed that bash Inspec resource was available from chef-Inspec docs - https://docs.chef.io/inspec_reference.html#bash, but githubdocs doesn’t show that https://github.com/chef/inspec/blob/master/docs/resources.rst. Am I doing it in a wrong way with the bash Inspec resource in my testcase OR I need latest version of kitchen-inspec to be installed? thanks.

kitchen-inspec (0.12.3, 0.12.1)
Chef Development Kit Version: 0.12.0
kitchen version: 1.6.0

bash Inspec:

describe bash('chmod +x *.sh') do
  it { should exist }
  its('stdout') { should match '/opt/tomcat/apache-tomcat-7.0.8/bin/' }
  its('exit_status') { should eq 0 }
end

Exception:

Class: Kitchen::ActionFailed
Message: Failed to complete #verify action: [undefined method `bash’ for #<#Class:0x007f89e2387958:0x007f89e2387368>]

@darknight This should work as expected. Please ensure that you have a recent version of inspec installed. It was first released with inspec v0.19.2
