[mihirvijdeshpande]

Version:

Test Kitchen version 2.10.0

Environment:

Ubuntu 20.04
Terraform 13.5
ruby 2.7.1

Using Kitchen-terraform to test aws infra

Scenario:

We are trying to run tests on resource aws_lambda but are unable to, the verify command fails with error.

Steps to Reproduce:

Write the following code in lambda_spec.rb:

control 'lambda' do
    describe aws_lambdas('tdd-terraform-lambda') do
        it { should exist}
        its ('handler') { should eq 'lambda'}
#        its ('version') { should eq '$LATEST' }
        its ('runtime') { should eq 'go1.x' }
    end
end

AWS Credentials exported in the ENV

run command kitchen converge to create aws resources >> this Passes

run command kitchen verify to run tests >> this Fails

Expected Result:

Run test and return result if Lambda function is present (or not)

Actual Result:
