API testing example

The purpose of this document is to be an easy guide for devs and testers to start testing REST APIs just in minutes.

For the examples we will be testing the Uber API using a YAML Swagger / Open API file and Reqres API using a normal Request Hash file.

To generate the Request Hashes from a Swagger / Open API file, run the file ./utils/import_swagger.rb or use the open_api_import command line executable.

If you want to automatically generate RSpec tests for every end point of your Swagger file, use the create_tests gem: https://github.com/MarioRuiz/create_tests
