Quarkus Mars Rover Http CLI

This CLI is designed to communicate with the mars rover http service and print out the names to the command line:

Mars Rovers:

0 - Spirit
1 - Opportunity
2 - Curiosity
3 - Perseverance
4 - Sojourner

These two applications combined show how http services can be mocked using WireMock and the Quarkus WireMock dev service. The MarRoverCliCommandTest is annotated with @ConnectWireMock which allows it to spin up a WireMock server in the background and load the stub mapping file in /src/test/resources/mappings. The mapping file defines the request the WireMock server will match and the response it will send back:

{
  "request": {
    "method": "GET",
    "url": "/rovers"
  },
  "response": {
    "status": 200,
    "headers": {
      "Content-Type": "application/json"
    },
    "jsonBody": [
      {
        "id": 0,
        "name": "Spirit - Test"
      },
      {
        "id": 1,
        "name": "Opportunity - Test"
      },
      {
        "id": 2,
        "name": "Curiosity - Test"
      },
      {
        "id": 3,
        "name": "Perseverance - Test"
      },
      {
        "id": 4,
        "name": "Sojourner - Test"
      }
    ]
  }
}

If you are new to mocking with WireMock, a good place to start is the Stubbing section of the documentation and then move onto the Request Matching and Response Templating sections.

WireMock Cloud

WireMock Cloud is a managed, hosted version of WireMock, developed by the same team who wrote the open-source project. It's built on the same technology that powers open source WireMock and is 100% compatible with the WireMock API, with additional features that make it quick and easy to mock any API you depend on. WireMock Cloud also introduces advanced capabilities such as chaos engineering, mock creation from openAPI spec, contract testing, import data from CSV files and the newer stateful mock functionality, as well as better collaboration and user management. WireMock Cloud has a free forever plan so take a look and see how WireMock Cloud can fit into your SDLC.

Quarkus

This project uses Quarkus, the Supersonic Subatomic Java Framework.

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./gradlew quarkusDev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.
