API tests

A Postman collection with API tests for https://petstore.swagger.io/

Prerequisites

Docker or Neman or Postman Desktop

Run the tests using Docker

Run Postman collection using newman in a docker container. In project directory run:

docker build -t postman-runner:latest .
docker run --rm postman-runner:latest run "./collections/PetStore_API_Tests.postman_collection.json" -e "./environments/PetStore_prod.postman_environment.json"

Run the tests using newman

In project directory run:

newman run "./collections/PetStore_API_Tests.postman_collection.json" -e "./environments/PetStore_prod.postman_environment.json"

Run the tests in Postman Desktop app

Open Postman. Import collection and environment (File -> Import -> path to the file). Click Runner. Select the collection and environment. Click Run.

Testing Notes

The expected output should contain assertion errors (I created tests in such a way that some of them fail) and be something like this:
