What is better for testing the REST APIs in the built-in Spring 3.1, soapUI or rest-assured ? oAuth 2.0 is used for authentication.
It depends on who is going to create and maintain the tests. If it is a QA, then soapUI is the right tool. If these are developers, then the rest is sure.
You can also use other tools for the REST API Testing , for example RestCase, Runscope or vRest . There are also many leisure clients such as postman, etc.
