Lab 9
RestAPI client testing of backend services
Lab Goal
To test all backend integration services with RestAPI call through web client and determine if
travel bookings are receiving hotel, car, flight and discounts.
ARCHITECTURE
RestAPI client testing of backend services
TESTING INTEGRATION
You finished the setup of OpenShift Container Platform, then built and deployed the
backend consisting of Hotel, Flights, Cars, Discount Rules and Integration services. The final
check is to make sure the integration endpoint is available and processing the services
correctly.
This requires the use of a REST client, for example in the lab images here, it will be done from
the Firefox browser using a plugin called RESTClient. You may use your own or install the
same one.
INTEGRATION ENDPOINT
- The integration endpoint is used to query the Destinasia backend systems only produces
results if it receives a REST query that it expects, but is available here:
- To test the services you can push the payload (request) to this endpoint, which is provided on the next slide.
INTEGRATION PAYLOAD
- The payload to be put into your REST client (red text only):
- Method:
POST
- Header:
Content-Type application/json
- URL:
http://fusetravelagency-appdev-in-cloud.192.168.99.100.nip.io/rest/book
- Body:
{"flightReq":{"flightFrom":"SIN","flightTo":"PEK","flightDate":"03/08/2017","flightPassengers":2,"flightNo":"SIN22"},"hotelReq":{"hotelArrivalDate":"03/08/2017","hotelNights":33,"hotelCity":"PEK","hotelId":"Marriott"},"carReq":{"carCity":"PEK","carRentalCo":"Hertz","carType":"Econ","carStartDate":"03/08/2017","carDays":33}}
FIXME: REST CLIENT URL
Install or use your own REST Client, starting by selecting the
Method and
URL:
- Method:
POST
- URL:
http://fusetravelagency-appdev-in-cloud.192.168.99.100.nip.io/rest/book

REST CLIENT BODY
Insert this
Body, ensure there are no line feed (returns):
- Body:
{"flightReq":{"flightFrom":"SIN","flightTo":"PEK","flightDate":"03/08/2017","flightPassengers":2,"flightNo":"SIN22"},"hotelReq":{"hotelArrivalDate":"03/08/2017","hotelNights":33,"hotelCity":"PEK","hotelId":"Marriott"},"carReq":{"carCity":"PEK","carRentalCo":"Hertz","carType":"Econ","carStartDate":"03/08/2017","carDays":33}}
REST CLIENT RESULTS
Submit the request via the
Save button and examine the
Response Body:
Flight, hotel and car backend services are working. Next up, testing discount rules by changing
the car information.
REST CLIENT DISCOUNTS
In the
Body, modify the
carRentalCo to anything other than
Hertz:
Send the request and see next slide to verify if the discount changes in the
Response Body
REST CLIENT TESTED
Did the car company discount response change from 15 for HERTZ to 0 for any others?
DESTINASIA SERVICES HERO
You are now the hero of the development team for delivering the Cloud hosted containerized
application services for end-to-end testing. Everyone is very happy with the automation and
repeatability for installing OpenShift Container Platform (OCP), JBoss Enterprise Application
Platform (EAP), JBoss Business Rules Management System (BRMS), several containerized web services
and test the end-to-end solution using a REST client.
Time to take a well deserved break...
