How to require a specific version of Serverspec for test-kitchen

Kallen · December 16, 2015, 1:32am

Hello. I’m pretty new to cookbook testing.

tl;dr – how do I restrict the version of Serverspec within test-kitchen? (if that is in fact a right thing to do).

We had a test-kitchen test integration suite that was working for one of our cookbooks, but today it started breaking. The cookbook converges fine; then the next step is to install Serverspec in order to run the serverspec tests.

Our systems still run ruby 1.9.3. We can’t just upgrade ruby quickly. I’m thinking that today’s Serverspec release of 2.25.0 as some newer dependencies which is just now causing this. (I haven’t verified this by digging into the gemspec of Serverspec 2.25.0).

I’m hoping a reasonable approach to keep our tests working is to restrict Serverspec to 2.24.x. Within our tests (not sure to call it test-kitchen or not), how can I restrict the Serverspec version? I tried this, but it didn’t work:


$ cat my-cookbook/test/integration/helpers/serverspec/spec_helper.rb
gem 'serverspec', '= 2.24.3'
require 'serverspec'
set :backend, :exec
12/16 01:19[root@the-test-host ~]# find /root/.gem/specs/ | grep -i serverspec

/root/.gem/specs/rubygems.org%443/quick/Marshal.4.8/serverspec-2.25.0.gemspec

Thanks in advance!

Hi Kallen,

Sorry, it seems that Discouse spoils quoted messages. This is what I said:

You need to create a Gemfile. For example


$ cat test/integration/default/serverspec/Gemfile
source 'https://rubygems.org'
gem 'serverspec', '~> 2.24.0'

The default refers to the name of your test-kitchen suite.

amaltson · December 16, 2015, 3:43pm

To build on what @zuazo said, you can put that Gemfile in test/integration/helpers/serverspec, it’ll be available in all your test suites rather than just the default one.

zuazo · December 16, 2015, 4:30pm

Rereading your question, the problem seems to be with the net-ssh gem, so:

$ cat test/integration/helpers/serverspec/Gemfile
gem 'net-ssh', '~> 2.0'

Kallen · December 16, 2015, 4:48pm

I got it to work. Thank you so much!

When I tried by putting serverspec into the Gemfile, I got this failure:


source 'https://rubygems.org'
 # gem 'serverspec', '~> 2.24.0'   # both this, and
  gem 'serverspec', '= 2.24.3' # this failed similarly

Is anyone experiencing the exact same fault but for Windows?

Adding the same Gemfile works for Linux. But not for Windows. I get the output below.
This is using ChefDK 0.6.0 and Chef-client 11.18.6.

This error makes sense as net-ssh does not support Ruby 1.9. This problem is not reproducible with Chef-Client 12 because that
comes with Ruby 2.x. However, our Infrastructure is still using Chef-Client 11.18.6 in
Production. So, as a result our CI still needs to test against it until we migrate fully to Chef Client 12.x
