[REQ] [Java] Support RestAssuredMockMvc

Is your feature request related to a problem? Please describe.

It is not related to a problem, but to a need. I would like the use of the rest-assured library with the java generator to also generate a class that implements the Oper class and that has a method similar to execute that could use RestAssuredMockMvc, this would end up helping a lot in creating better abstractions in tests.

Describe the solution you'd like

As said above, it would be another class very similar to the current generated classes that implement the Oper class, but with a difference. These classes would be test-specific, and their execute methods would use RestAssuredMockMvc instead of RestAssured.

Describe alternatives you've considered

Any implementation similar to the one that exists today but using RestAssuredMockMvc would serve me well.

Additional context

Unfortunately I am unable to create a prototype for review, but I believe this request would be a great addition to the project.

Start by locating the Java generator's current generated classes that implement Oper and their execute methods, then compare how they use RestAssured. Define the test-specific class behavior around RestAssuredMockMvc and confirm that the generated output supports the requested testing abstraction.
