AT

• Workflow
  • I can populate some data in elastic search
  • Aggregation is executed
  • I can assert the results
• Can be run with a maven command

Hints

• I find this article explaining pretty good different options which one has for integration testing https://gquintana.github.io/2016/11/30/Testing-a-Java-and-Elasticsearch-50-application.html
• additionally there is a separate maven plugin, which also looks pretty nice https://github.com/alexcojocaru/elasticsearch-maven-plugin
