[chef] Re: How to test a bash code snippet

[Daniel Condomitti < >]

This isn't directly related to your testing but you can just run `bundle check` and it will tell you if any gems need to be installed or upgraded. If you're only testing for xpath 0.1.4's existence then if another gem gets upgraded you won't be able to boot your application.

Hi,

I'm using chefspec with chef 11 and have this working piece of code but

don't know how to test it.

I hope this is the correct place to ask for any suggestions on this?

I also have a crude file exists check so that bundle doesn't run every chef_run.

bash "install with bundler" do

  user "vagrant"

  cwd "/vagrant"

  flags "--login"

  code <<-EOH

  rvm use ruby-1.9.2-p290

  bundle --verbose

  EOH

  # xpath is the last in the list of 125 required gems for this application (gem list --local)

  # If this gem is here we assume bundle has already run successfully.

  not_if { ::File.exists?('/home/vagrant/.rvm/gems/ruby-1.9.2-p290/gems/xpath-0.1.4') }

end

Prior to this code I was testing the execute command with this:

describe 'main::install_bundle' do

  let (:chef_run) { ChefSpec::ChefRunner.new.converge 'main::install_bundle' }

  it "installs with bundler" do

    expect(chef_run).to execute_command("cd /vagrant && rvm use ruby-1.9.2-p290 && bundle --verbose")

  end

end

But I need the "--login" flag so that rvm can select ruby 1.9.2 so I changed to the bash resource.

FYI ..chef is running with ruby 1.9.3 but the Rails app uses 1.9.2 on the /vagrant box (it's some old coder I need to maintain).

Thanks!
