API Testing Using Postman Tool

Abstract: Postman is one of the greatest API automation and documentation tools available today. Postman began as a simple Chrome browser plugin and has now grown to be a full API testing solution used by 5 million developers and over 100,000 enterprises all over the world. With a $2 billion value, it's a unicorn in its own right, and it's become the go-to platform for creating enterprise APIs. As the API economy continues to growing, more challenges are created for developers. The old methods of manually creating and testing APIs no longtime scale as today’s software and services can interface with hundreds of APIs within a single application. Development, testing, and delivery teams must work together to make sure that applications work barrier with APIs to provide a business advantage, rather than cause a business obstacle. Collaboration and operational efficiency are the keys to sharing modern API- powered applications. And this is the space that Postman plays in. In one of our GlobalLogic projects related to a Banking as well as Financial Services Customer Communications Management platform that is CCMP, we need to use Postman and its CI/CD add-on Newman to create, customize and automate Web API tests. This white paper and technical report narrate our passage direct this automation and showcases some learnings and best practices realized along the way. This is our view from the trenches on the capacity and possibilities of the Postman platform for API testing
