The preferred way of locally testing the role is to use Docker. You will have to install Docker on your system. See Get started for a Docker package suitable to for your system.
You can also use vagrant and Virtualbox or VMWare to run tests locally. You will have to install Virtualbox and Vagrant on your system. See Vagrant Downloads for a vagrant package suitable for your system. For all our tests we use
test-kitchen. If you are not familiar with
test-kitchen please have a look at their guide.
Next install test-kitchen:
# Install dependencies gem install bundler bundle install
Testing with Docker
# fast test on one machine bundle exec kitchen test default-ubuntu-1204 # test on all machines bundle exec kitchen test # for development bundle exec kitchen create default-ubuntu-1204 bundle exec kitchen converge default-ubuntu-1204
Testing with Virtualbox
# fast test on one machine KITCHEN_YAML=".kitchen.vagrant.yml" bundle exec kitchen test nginx-ansible-19-ubuntu-1404 # test on all machines KITCHEN_YAML=".kitchen.vagrant.yml" bundle exec kitchen test # for development KITCHEN_YAML=".kitchen.vagrant.yml" bundle exec kitchen create nginx-ansible-19-ubuntu-1404 KITCHEN_YAML=".kitchen.vagrant.yml" bundle exec kitchen converge nginx-ansible-19-ubuntu-1404
