Integration testing your legacy java microservice with docker-maven-plugin

The docker-maven-plugin enables a stack of Docker containers to be started and stopped by maven to support integration testing of a java application.

This presentation will describe a legacy java microservice application that had no automated tests. By mocking service dependencies in Docker containers, a collection of integration tests were implemented with JUnit.

I'll demonstrate how the same set of integration tests can be launched using docker-compose interactively and using the docker-maven-plugin as a scripted solution.

This presentation will make use of the following resources.
