ChefDK and rake

Chef Infra (archive)

I’m testing a cookbook I set up with mis using the ChefDK environment.

I have done chef shell-init and
which rspec returns

/opt/chefdk/embedded/bin/rspec

This command runs the chefspec tests.

chef exec rspec test/unit/spec

However this rake task fails with error suggesting it’s using the wrong
rspec

require 'rspec/core/rake_task’
desc 'Run ChefSpec unit tests’
RSpec::Core::RakeTask.new(:spec) do |t, _args|
t.rspec_opts = 'test/unit/spec’
end

Is there something obvious I’m missing to make this work?

Just checking, you did eval "$(chef shell-init bash)” ?

chef exec rspec test/unit/spec
You don’t need chef exec if you configure your shell via shell-init.

What’s the error?

require 'rspec/core/rake_task'
desc 'Run ChefSpec unit tests'
RSpec::Core::RakeTask.new(:spec) do |t, _args|
t.rspec_opts = 'test/unit/spec'

Yes, rspec test/unit/spec on the command line works as well. So the
shell-init part is correct.

I did the obvious after a little googling and added this to the rake file

require 'rspec/core/rake_task'
desc 'Run ChefSpec unit tests'
RSpec::Core::RakeTask.new(:spec) do |t, _args|
t.rspec_opts = 'test/unit/spec'
t.rspec_path = '/opt/chefdk/embedded/bin/rspec'
end

And now I get this error, which seems pretty odd. This is the error I was
originally getting, I thought it meant I was
running a different rspec, but apparently not.

Hi Booker,

ChefDK is new enough that I’m not sure what the ‘ChefDK’ way is. But I’d use bundler and a Gemfile in your project, so that all your gems (rspec, etc) are using the same Gem versions.

I did find this bug:
https://github.com/opscode/chef-dk/issues/18

That suggests you may be able to do ‘chef run rake’ or something like that and get the same rake+rspec you get from running rspec yourself. Or get the chef paths and hooks in front of your rake command by running – eval “$(chef shell-init bash)” – I haven’t tested that, though. It sounds like down the road they plan on wrapping all that with a ‘chef test’ command, too.

Hope this helps,
