TDD with Test Kitchen

App test vs Cookbook Test

• Test configuration can be defined in two different places.
• One is inside app directory myapp/test/recipes/default_test.rb
• Another one is inside the cookbooks directory myapp/cookbooks/mycookbook/test/recipes/default_test.rb

Inspec vs Serverspec

• Inspec resources
• Serverspec resources

Creating test file

User Resource

• Add inspec user resource to check for tomcat user

unless os.windows?
  describe user('tomcat') do
    it { should exist }
  end
end

Port Resource

• Add inspec port resource to verify listening of port 8080
• Include protocols for tcp6

describe port(8080) do
  it { should be_listening }
  its('protocols') { should include 'tcp6' }
end

Service Resource

• Add inspec service resource to verify tomcat service
• Include installed, enabled and running conditions

describe service('tomcat') do
  it { should be_installed }
  it { should be_enabled }
  it { should be_running }
end

Complete file of /workspace/myapp/test/recipes/default_test.rb is as follows

unless os.windows?
  describe user('tomcat') do
    it { should exist }
  end
end

describe port(8080) do
  it { should be_listening }
  its('protocols') { should include 'tcp6' }
end

describe service('tomcat') do
  it { should be_installed }
  it { should be_enabled }
  it { should be_running }
end
