Background:

I have a simple Spring Boot application consisting of three services. The services communicate via HTTP REST calls. Below is a brief description of the services.

• Mission planner (localhost:9100)

  • Orchestrates the "planning" of a mission. Invokes the Route Generator and Route Assessor services to do the work. The "plan mission" action is triggered by a POST (/v1/missionServices/missionPlanning/planMission) from a "client". A simple response message is returned to the caller.

• Route Generator (localhost:9110)

  • Generates a "route" when invoked by the mission planner (/v1/missionServices/missionPlanning/generateRoute). Returns a response message to the mission planner.

• Route Assessor (localhost:9120)

  • Assesses the generated "route" when invoked by the mission planner (/v1/missionServices/missionPlanning/assessRoute). Returns a response message to the mission planner.

The mission planner "client" is a fourth service that triggers the "plan mission" process by sending a POST request to the mission planner. This is not part of the integration test. Instead, the Citrus test takes its place.

Objective:

I'm attempting to use the Citrus Framework to perform integration tests on the services, separately and as a whole (end-to-end). I have been successful with the simpler service cases (i.e. the route generator and route assessor), but testing the mission planner has proven to present many difficulties.

Below is the Citrus test I've written for the mission planner. Currently I am "mocking" the route generator and route assessor services, but for an end-to-end test, will need to figure out how to do this will all three services "live" - I won't worry about that for now. I have built this based on examples I have found and from what I have learned during my experience.
