Using InSpec in 'kitchen verify' fails due to net-ssh gem constraint conflicts.

[jzohrab]

With the Chef Development Kit Version 0.10.0 and inspec set as the .kitchen.yml verifier, kitchen verify fails with the below:

>>>>>> ------Exception-------
>>>>>> Class: Kitchen::ActionFailed
>>>>>> Message: Failed to complete #verify action: [Unable to activate specinfra-2.43.9, because net-ssh-3.0.2 conflicts with net-ssh (~> 2.7)]
>>>>>> ----------------------
>>>>>> Please see .kitchen/logs/kitchen.log for more details
>>>>>> Also try running `kitchen diagnose --all` for configuration

Ruby version: ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin13]

Some gems I have installed:

$ gem list | grep spec ... and edited a bit
chefspec (4.4.0)
inspec (0.9.10, 0.9.9)
kitchen-inspec (0.10.1)
rspec (3.4.0, 3.3.0, 2.11.0)
serverspec (2.24.1)
specinfra (2.43.9)

$ gem list | grep net-ssh
net-ssh (3.0.2, 2.9.4, 2.9.2, 2.9.1)

The .kitchen/logs/ubuntu log had the following:

Working through this and will post notes as I go, rather than at the end in a nice neat report. Will clean up the comments in here when I get everything worked out, maybe.

Upgrading specinfra to latest version (gem install specinfra -v 2.50.4), which uses updated net-ssh gem, gives a different error:

Message: Failed to complete #verify action: [undefined local variable or method `failure_slash_error_line' for #<RSpec::Core::Formatters::ExceptionPresenter:0x007fab04936550>]

Ref https://twitter.com/kantrn/status/664913752832126976 for a tweet on the above.

https://rubygems.org/gems/specinfra/versions/2.44.8 is the lowest number that changes the net-ssh ~> 2.7 dependency. It has dependency net-ssh < 3.1, >= 2.7, but unfortunately installing that gem also leads to the undefined local variable or method 'failure_slash_error_line' issue.

Submitted PR https://github.com/mizzy/serverspec/pull/553 to serverspec to deal with the error above.

This is verified working on ChefDK 0.15.15
