Question

In Spring MVC 3.0, how do I test that a particular method gets invoked?

For example, I have this controller method:

public class myController {
    @RequestMapping(value = "/create", method = RequestMethod.GET)
    public ModelAndView create(ModelMap map) {
            map.put("category", new Category());
            return new ModelAndView("views/someView", map);
        }
}

How do I test that this create() method gets called when somebody requests http://example.com/create url.

In Unit Tests, you should only test your controller’s Java code, without using any Servlet technology.

In integration tests you can do one of several things:

Use the org.springframework.mock.web package in the spring-test artifact, which contains Mock Objects for request, response, servletContext to fire fake requests at your controllers and read the data from the fake responses.

Or use a web testing framework like Selenium that works against a deployed webapp.
