REST mocks implementation sample with SoapUI

Part of five-cents demo

This topic is part of the ‘contract’ system of the Five-cents demo :

Five cents demo general schema - backend - contract

GitHubThe source code is available on GitHub, under /backends/contract folder.

 

Build REST mocks with SOAPUi

Our only concern, for this part of the demo, is to build a quick and dirty contract system that responds to contract requests. A great full-featured mocking tool that can be used to mock full parts of systems is Microcks, and it will be the subject of a few blogs to come up. For now, we will just stick to simple SOAPUi mocks to fulfill our needs.

You will find the SOAPUi project with our mocks under https://github.com/lcailleteau/fivecents-microservices-demo/blob/master/backends/contract/soapui-mocks/contract-soapui-project.xml. Basically it just displays JSON responses to contracts request for a given client :

And that’s it !

We can launch the mock service outside SOAPUi program with the help of those commands :

export SOAPUI_HOME_FOLDER="/home/cailleteau/SmartBear/SoapUI-5.4.0"
export SOAPUI_PROJECT="/media/Donnees/Users/Laurent/blog/fivecents-microservices-demo/backends/contract/soapui-mocks/contract-soapui-project.xml"
fivecents-microservices-demo/backends/contract/launch-contracts-mocks.sh

It should display :

SOAPUI_HOME_FOLDER : /home/cailleteau/SmartBear/SoapUI-5.4.0
SOAPUI_PROJECT : /media/Donnees/Users/Laurent/blog/fivecents-microservices-demo/backends/contract/soapui-mocks/contract-soapui-project.xml

We can try a request on the mock, to fetch all contracts of client with id 0 :

curl http://localhost:8080/0/contracts

And ckeck the result :

{
  "car-contracts": [
    {
      "id": 4870,
      "start-day": 28,
      "start-month": 11,
      "start-year": 2011,
      "model": "renault twingo"
    }
  ],
  "home-contracts": [
    {
      "id": 4871,
      "start-day": 28,
      "start-month": 11,
      "start-year": 2011}
  ]
}
