During this talk, you will explore the docker-compose-testkit. This is an open-source asynchronous testing framework (implemented in Scala) that allows docker containers to be instrumented (instrumentation sensors are modelled by Observables), deployed (e.g. by docker-compose) and then fault injected (fault injection points are modelled by Observers). Abstraction layers allow the same testing code to target both local environments and cloud environments (e.g. AWS, DC/OS, etc.).
A Scala DSL is introduced to define composable and modular state machines that allow one to both monitor these sensors at runtime and to match against expected outcomes. Using for-comprehensions, complex testing scenarios may be defined that allow for warm-up and fault injection.
You will discover full code demonstrating a wide range of example scenarios, along with live coding demonstrations.
The Call for Papers is now open for Scala eXchange 2017! Submit your talk for the chance to join a stellar line-up of experts on stage. Find out more.
