SmartBear Software has released Ready! API TestServer, an automated API testing solution which hopes to allow developers to find bugs faster and speed the delivery of APIs. It is important to test APIs, as they represent the critical building blocks of business functions and revenue streams.
While there are numerous API testing solutions, the Ruby Airborne API tester Gem will be of interest to those with a strong inclination towards the Ruby platform. If you follow along all the steps you'll create an API test running against the Trello API, a real API with formal authentication tokens.
