Imagine if you could create, for people in your company, a platform that would provide them with the same experience they have when working with AWS, Google Cloud, Azure, or any other public Cloud provider. Imagine if there would be a service for everything they do.
Do you need a database that works exactly as we expect it to work in this company with all the security, backup, compliance, and other policies we have?
Well...
There is a service for that.

| -- Ansible testing using Assert | |
| When we run Ansible to manage server configurations, we assume (if there is no red errors) that it worked. But if you are developing ansible modules for your systems, and want to take the DevOps approach and work on CICD pipelines, you need to have some tests in there to prove that what you asked ansible to do has actually worked. | |
| One of the best ways to do this within ansible, is to use the Assert module. It asserts that a given expression is true. When you combine this with the output of a command that’s registered to a variable, there is almost no limit to what you can test. | |
| I’m going to use the TDD (Test driven development) method where we create the tests before we start writing any ansible code to manage our systems. I expect the tests to fail. Then we’ll write ansible to pass the tests. That’s it. | |
| This demo will cover the following: | |
| • Create some tests using the command and assert modules. |
