Inspec json resource . example not working

[alexpop]

Description

The json inspec resource not working with '.' as separators.

InSpec and Platform Version

$ bin/inspec version
0.18.0

OS X 10.11.3

Replication Case

With the following json file:

{
  "cookbook_locks": {
    "omnibus": {
      "version": "2.2.0",
      "identifier": "22b35f3f9273cb8d8b6ac3684cb92f960597ff2f"
    }
  }
}

The json inspec resource documentation and example show this:

describe json('policyfile.lock.json') do
  its('cookbook_locks.omnibus.version') { should eq('2.2.0') }
end

On execution, it gives this error message:

$ bin/inspec exec /tmp/json_test.rb
F
Failures:
  1) Json /tmp/Policyfile.lock.json cookbook_locks.omnibus.version
     Failure/Error: with.run_specs(tests)

     NoMethodError:

Finished in 0.00093 seconds (files took 1.06 seconds to load)
1 example, 1 failure

Failed examples:
rspec  # Json /tmp/Policyfile.lock.json cookbook_locks.omnibus.version

The workaround I found was to run it like this:

describe json('/tmp/Policyfile.lock.json') do
  its(['cookbook_locks','omnibus','version']) { should eq('2.2.0') }
end

producing the correct output:

$ bin/inspec exec /tmp/json_test.rb
.

[chris-rock]

Unfortunately, this is an issue with its. We need to update the documentation for the resource to use:

describe json('/tmp/Policyfile.lock.json') do
  its(['cookbook_locks','omnibus','version']) { should eq('2.2.0') }
end

for now
