Writing good tests for your existing deployments or distributed software infrastructure should be painless, and easily accomplishable without involving any time-consuming and complex testing setup. This is where goodplay comes into play.

goodplay instruments Ansible — “a radically simple IT automation platform” as it is advertized — and allows you to write your tests in the same simple and probably already familiar language you would write an Ansible playbook.


  • define your test environments via Docker Compose and Ansible inventories
  • write your tests as Ansible 2.x playbook tasks
  • resolve and auto-install Ansible role dependencies prior to test run
  • run your tests within Docker container(s), an already existing test environment, or on localhost
  • built as a pytest plugin to have a solid test runner foundation, plus you can run your goodplay tests together with your other tests


goodplay will use Semantic Versioning when reaching v1.0.0. Until then, the minor version is used for backwards-incompatible changes.

goodplay vs. Other Software

In this section we compare goodplay to some of the other software options that are available to partly solve what goodplay can accomplish for you.


Ansible itself comes bundled with some testing facilities mentioned in the Ansible Testing Strategies documentation. It makes a low-level assert module available which helps to verify that some condition holds true, e.g. some output from a previous task which has been stored in a variable contains an expected value.

Although it can be sometimes necessary to use something low-level as Ansible’s assert, goodplay enables you to use high-level modules for describing your test cases.

Besides the actual testing, goodplay takes care of setting up and tearing down the test environment as well as collecting the test results – both being something Ansible was not made for.


pytest-ansible is as the name already implies a pytest plugin just like goodplay. But instead of being used for testing Ansible playbooks or roles, it provides pytest fixtures that allow you to execute Ansible modules from your Python-based tests.


serverspec seems to be more targeted to assert hosts are in a defined state. In comparison to goodplay it allows you to run tests against single hosts only and does not include test environment management.
