3.4.4. - Swagger UI Tests

Although this project is meant to be used with Locust and for benchmark testing and rate-limiting, it may be interesting to understand the data model first. Swagger UI helps with that.

Please run make docker-clean-build-start before anything. If you are running the services outside Docker, please make sure to have these environment variables assigned: POSTGRESQL_HOST=localhost;REDIS_HOST=localhost

Here are the endpoints for the services with the open port:

• buy-oyc-api-service
• buy-oyc-catering-service
• buy-oyc-concert-service
• buy-oyc-parking-service
• buy-oyc-ticket-service

Via Kong Gateway for swagger.yml

• http://localhost:8000/api/yucca-api/swagger/swagger.yml
• http://localhost:8000/api/yucca-ticket/swagger/swagger.yml
• http://localhost:8000/api/yucca-parking/swagger/swagger.yml
• http://localhost:8000/api/yucca-catering/swagger/swagger.yml
• http://localhost:8000/api/yucca-concert/swagger/swagger.yml

Via Kong Gateway for Swagger UI

• http://localhost:8000/api/yucca-api/swagger/views/swagger-ui/index.html
• http://localhost:8000/api/yucca-ticket/swagger/views/swagger-ui/index.html
• http://localhost:8000/api/yucca-parking/swagger/views/swagger-ui/index.html
• http://localhost:8000/api/yucca-catering/swagger/views/swagger-ui/index.html
• http://localhost:8000/api/yucca-concert/swagger/views/swagger-ui/index.html

Make sure to check the e2e tests in order to see how Swagger is implemented. The Explorer textbox needs to be manually configured at the moment.

3.4.5 Cypress tests

In order to run cypress tests, please run

make dcup-full

Then go to the e2e folder and run:

make cypress-open

The cypress test management window should open and you should be able to perform your tests manually.
