Summary

API specifications give you a lot of power in your testing. You can use them to keep documentation, tests, and even underlying code all in sync with each other. In this chapter, you learned how to use them to reduce the work in generating mocks and collections in Postman. You have learned how to create an OAS to document an API. You can also read API specs that others may have made, and you have the ability to use those in Postman. You have learned how to leverage an API specification to help you automatically create tests and mocks in Postman. You have also learned how to validate that tests in Postman are set up to be consistent with the documentation and code produced from a specification. In addition to that, you have learned how to use specifications in Postman to verify that the data being sent and received from a request is in the proper format. Taken as a whole, you have gained a lot of useful skills for using an API specification to help with testing and designing...
