RestFuse vs Rest Assured vs MockMVC Rest Service Unit Test Framework

I've been trying to find a simple all purpose unit test framework for Spring MVC based Rest Services I've written.

I've been searching online and narrowed it down to:

I like RestFuse because it's mostly annotation based, but rest assured seems to have a easier way of passing parameters and checking responses. And finally being a Spring MVC Rest Service project, I'm wondering if I should just stick with the already established way of testing Rest Services in Spring with MockMVC.

Interested to get any feedback, as well as performance, past experiences and if there's anything else I should take into consideration.

Rest-Assured is gaining acceptance over the other frameworks to test REST services in Java. Having BDD style fluent interface, its easy to read the test scripts also, with minimal learning curve.

I am using this framework for verifying REST services as an end user, and it has been easier to implement test scripts for them. Hence I cannot comment much on Spring MVC part of REST-assured.

However, this blog post gives you more details on RestAssured v2.2 which includes spring-mock-mvc module built on top of MockMVC giving BDD style fluent interface flavor through REST assured. The blog post also cautions:

When not to use it:

RestAssuredMockMvc is not to be considered a complete replacement to vanilla MockMvc since it contains more specific features coupled to Spring MVC. For example right now there’s no first class support for things like flash attributes and principals. You can how ever add those by using an interceptor. Standard REST Assured also supports a lot of different authentication schemes and filters which are not available in the RestAssuredMockMvc API. Another reason for why you may want to use the standard REST Assured API is if it’s important to your organization to test the REST API in a real container (for example if you’ve configured authentication or authorization in a container specific manner) or if you’re using JAX-RS (or any other framework regardless of language).

Finally, have a look at REST-Assured spring-mvc-webapp examples in REST-assured codebase, and decide, whether you like to give a try for it and make the best use of both REST-assured and MockMVC frameworks.
